* Memcached sessions: add session data on initialization; don't silently discard exceptions; add unit tests.  #9823 [kamk]

* error_messages_for also takes :message and :header_message options which defaults to the old "There were problems with the following fields:" and "<count> errors prohibited this <object_name> from being saved".  #8270 [rmm5t, zach-inglis-lt3]

* Make sure that custom inflections are picked up by map.resources.  #9815 [mislav]

* Changed SanitizeHelper#sanitize to only allow the custom attributes and tags when specified in the call [DHH]

* The tag helper may bypass escaping.  [Jeremy Kemper]

* Cache asset ids.  [Jeremy Kemper]

* Optimized named routes respect AbstractRequest.relative_url_root.  #9612 [danielmorrison, Jeremy Kemper]

* Introduce ActionController::Base.rescue_from to declare exception-handling methods. Cleaner style than the case-heavy rescue_action_in_public.  #9449 [norbert]

* Rename some RequestForgeryProtection methods.  The class method is now #protect_from_forgery, and the default parameter is now 'authenticity_token'.  [Rick]

* Merge csrf_killer plugin into rails.  Adds RequestForgeryProtection model that verifies session-specific _tokens for non-GET requests.  [Rick]

* Secure #sanitize, #strip_tags, and #strip_links helpers against xss attacks.  Closes #8877. [Rick, lifofifo, Jacques Distler]

* Added FormHelper#label.  #8641, #9850 [jcoglan, jarkko]

* Added AtomFeedHelper (slightly improved from the atom_feed_helper plugin) [DHH]

* Prevent errors when generating routes for uncountable resources, (i.e. sheep where plural == singluar).   map.resources :sheep now creates sheep_index_url for the collection and sheep_url for the specific item.  [Koz]

* Added support for HTTP Only cookies (works in IE6+ and FF 2.0.5+) as an improvement for XSS attacks #8895 [lifo/Spakman]

* Don't warn when a path segment precedes a required segment. Closes #9615. [Nicholas Seckar]

* Fixed CaptureHelper#content_for to work with the optional content parameter instead of just the block #9434 [sandofsky/wildchild].

* Added Mime::Type.register_alias for dealing with different formats using the same mime type [DHH]. Example:

    class PostsController < ApplicationController
      before_filter :adjust_format_for_iphone

      def index
        @posts = Post.find(:all)
        
        respond_to do |format|
          format.html   # => renders index.html.erb and uses "text/html" as the content type
          format.iphone # => renders index.iphone.erb and uses "text/html" as the content type
        end
      end


      private
        def adjust_format_for_iphone
          if request.env["HTTP_USER_AGENT"] && request.env["HTTP_USER_AGENT"][/iPhone/]
            request.format = :iphone
          end
        end
    end

* Added that render :json will automatically call .to_json unless it's being passed a string [DHH].

* Autolink behaves well with emails embedded in URLs.  #7313 [Jeremy McAnally, tarmo]

* Fixed that default layouts did not take the format into account #9564 [lifofifo]

* Fixed optimized route segment escaping.  #9562 [wildchild, Jeremy Kemper]

* Added block acceptance to JavaScriptHelper#javascript_tag.  #7527 [Bob Silva, Tarmo Tänav, rmm5t]

* root_path returns '/' not ''.  #9563 [lifofifo]

* Fixed that setting request.format should also affect respond_to blocks [DHH]

* Add option to force binary mode on tempfile used for fixture_file_upload.  #6380 [Jonathan Viney]

* Fixed that resource namespaces wouldn't stick to all nested resources #9399 [pixeltrix]

* Moved ActionController::Macros::AutoComplete into the auto_complete plugin on the official Rails svn #9512 [lifofifo]

* Moved ActionController::Macros::InPlaceEditing into the in_place_editor plugin on the official Rails svn #9513 [lifofifo]

* Removed deprecated form of calling xml_http_request/xhr without the first argument being the http verb [DHH]

* Removed deprecated methods [DHH]:

  - ActionController::Base#keep_flash (use flash.keep instead)
  - ActionController::Base#expire_matched_fragments (just call expire_fragment with a regular expression)
  - ActionController::Base.template_root/= methods (use ActionController#Base.view_paths/= instead)
  - ActionController::Base.cookie (use ActionController#Base.cookies[]= instead)

* Removed the deprecated behavior of appending ".png" to image_tag/image_path calls without an existing extension [DHH]

* Removed ActionController::Base.scaffold -- it went through the whole idea of scaffolding (card board walls you remove and tweak one by one). Use the scaffold generator instead (it does resources too now!) [DHH]

* Optimise named route generation when using positional arguments.  [Koz]

  This change delivers significant performance benefits for the most
  common usage scenarios for modern rails applications by avoiding the
  costly trip through url_for.  Initial benchmarks indicate this is
  between 6 and 20 times as fast.

* Explicitly require active_record/query_cache before using it.  [Jeremy Kemper]

* Fix layout overriding response status.  #9476 [lotswholetime]

* url_for now accepts a series of symbols representing the namespace of the record [Josh Knowles]

* Make :trailing_slash work with query parameters for url_for. Closes #4004 [nov]

* Make sure missing template exceptions actually say which template they were looking for.  Closes #8683 [dasil003]

* Fix errors with around_filters which do not yield, restore 1.1 behaviour with after filters. Closes #8891 [skaes]

  After filters will *no longer* be run if an around_filter fails to yield, users relying on
  this behaviour are advised to put the code in question after a yield statement in an around filter.
  

* Allow you to delete cookies with options. Closes #3685 [josh, Chris Wanstrath]

* Allow you to render views with periods in the name.  Closes #8076 [norbert]

  render :partial => 'show.html.erb'

* Improve capture helper documentation.  #8796 [kampers]

* Prefix nested resource named routes with their action name, e.g. new_group_user_path(@group) instead of group_new_user_path(@group). The old nested action named route is deprecated in Rails 1.2.4.  #8558 [David Chelimsky]

* Allow sweepers to be created solely for expiring after controller actions, not model changes [DHH]

* Added assigns method to ActionController::Caching::Sweeper to easily access instance variables on the controller [DHH]

* Give the legacy X-POST_DATA_FORMAT header greater precedence during params parsing for backward compatibility.  [Jeremy Kemper]

* Fixed that link_to with an href of # when using :method will not allow for click-through without JavaScript #7037 [stevenbristol/josh]

* Fixed that radio_button_tag should generate unique ids #3353 [BobSilva/rebecca/josh]

* Fixed that HTTP authentication should work if the header is called REDIRECT_X_HTTP_AUTHORIZATION as well #6754 [mislaw]

* Don't mistakenly interpret the request uri as the query string.  #8731 [lifofifo, Jeremy Kemper]

* Make ActionView#view_paths an attr_accessor for real this time.  Also, don't perform an unnecessary #compact on the @view_paths array in #initialize.  Closes #8582 [dasil003, julik, rick]

* Tolerate missing content type on multipart file uploads. Fix for Safari 3.  [Jeremy Kemper]

* Deprecation: remove pagination. Install the classic_pagination plugin for forward compatibility, or move to the superior will_paginate plugin.  #8157 [Josh Peek]

* Action caching is limited to GET requests returning 200 OK status.  #3335 [tom@craz8.com, halfbyte, Dan Kubb, Josh Peek]

* Improve Text Helper test coverage.  #7274 [Rob Sanheim, Josh Peek]

* Improve helper test coverage.  #7208, #7212, #7215, #7233, #7234, #7235, #7236, #7237, #7238, #7241, #7243, #7244 [Rich Collins, Josh Peek]

* Improve UrlRewriter tests.  #7207 [Rich Collins]

* Resources: url_for([parent, child]) generates /parents/1/children/2 for the nested resource. Likewise with the other simply helpful methods like form_for and link_to.  #6432 [mhw, Jonathan Vaught, lotswholetime]

* Assume html format when rendering partials in RJS. #8076 [Rick]

* Don't double-escape url_for in views.  #8144 [Rich Collins, Josh Peek]

* Allow JSON-style values for the :with option of observe_field.  Closes #8557 [kommen]

* Remove RAILS_ROOT from backtrace paths.  #8540 [Tim Pope]

* Routing: map.resource :logo routes to LogosController so the controller may be reused for multiple nestings or namespaces.  [Jeremy Kemper]

* render :partial recognizes Active Record associations as Arrays.  #8538 [kamal]

* Routing: drop semicolon and comma as route separators.  [Jeremy Kemper]

* request.remote_ip understands X-Forwarded-For addresses with nonstandard whitespace.  #7386 [moses]

* Don't prepare response when rendering a component.  #8493 [jsierles]

* Reduce file stat calls when checking for template changes.  #7736 [alex]

* Added custom path cache_page/expire_page parameters in addition to the options hashes [DHH]. Example:

    def index
      caches_page(response.body, "/index.html")
    end

* Action Caching speedup.  #8231 [skaes]

* Wordsmith resources documentation.  #8484 [marclove]

* Fix syntax error in code example for routing documentation. #8377. [norbert]

* Routing: respond with 405 Method Not Allowed status when the route path matches but the HTTP method does not.  #6953 [Josh Peek, defeated, Dan Kubb, Coda Hale]

* Make assert_select's failure messages clearer about what failed. #7779 [dchelimsky]

* Introduce a default respond_to block for custom types.  #8174 [Josh Peek]

* auto_complete_field takes a :method option so you can GET or POST.  #8120 [zapnap]

* Added option to suppress :size when using :maxlength for FormTagHelper#text_field #3112 [rails@tpope.info]

* catch possible WSOD when trying to render a missing partial. Closes #8454 [Catfish]

* Rewind request body after reading it, if possible.  #8438 [s450r1]

* Resource namespaces are inherited by their has_many subresources.  #8280 [marclove, ggarside]

* Fix filtered parameter logging with nil parameter values.  #8422 [choonkeat]

* Integration tests: alias xhr to xml_http_request and add a request_method argument instead of always using POST.  #7124 [Nik Wakelin, Francois Beausoleil, Wizard]

* Document caches_action.  #5419 [Jarkko Laine]

* Update to Prototype 1.5.1.  [Sam Stephenson]

* Allow routes to be decalred under namespaces [Tobias Luetke]: 
  
  map.namespace :admin do |admin|
    admin.root :controller => "products"       
    admin.feed 'feed.xml', :controller => 'products', :action => 'feed', :format => 'xml'
  end
  
* Update to script.aculo.us 1.7.1_beta3.  [Thomas Fuchs]

* observe_form always sends the serialized form.  #5271 [manfred, normelton@gmail.com]

* Parse url-encoded and multipart requests ourselves instead of delegating to CGI.  [Jeremy Kemper]

* select :include_blank option can be set to a string instead of true, which just uses an empty string.  #7664 [Wizard]

* Added url_for usage on render :location, which allows for record identification [DHH]. Example:

    render :xml => person, :status => :created, :location => person
  
  ...expands the location to person_url(person).

* Introduce the request.body stream. Lazy-read to parse parameters rather than always setting RAW_POST_DATA. Reduces the memory footprint of large binary PUT requests.  [Jeremy Kemper]

* Add some performance enhancements to ActionView.

  * Cache base_paths in @@cached_base_paths
  * Cache template extensions in @@cached_template_extension
  * Remove unnecessary rescues

* Assume that rendered partials go by the HTML format by default

  def my_partial
    render :update do |page|
      # in this order
      # _foo.html.erb
      # _foo.erb
      # _foo.rhtml
      page.replace :foo, :partial => 'foo'
    end
  end

* Added record identifications to FormHelper#form_for and PrototypeHelper#remote_form_for [DHH]. Examples:

    <% form_for(@post) do |f| %>
      ...
    <% end %>
  
  This will expand to be the same as:
  
    <% form_for :post, @post, :url => post_path(@post), :html => { :method => :put, :class => "edit_post", :id => "edit_post_45" } do |f| %>
      ...
    <% end %>
  
  And for new records:
  
    <% form_for(Post.new) do |f| %>
      ...
    <% end %>
  
  This will expand to be the same as:
  
    <% form_for :post, @post, :url => posts_path, :html => { :class => "new_post", :id => "new_post" } do |f| %>
      ...
    <% end %>

* Rationalize route path escaping according to RFC 2396 section 3.3.  #7544, #8307. [Jeremy Kemper, chrisroos, begemot, jugend]

* Added record identification with polymorphic routes for ActionController::Base#url_for and ActionView::Base#url_for [DHH]. Examples:

    redirect_to(post)         # => redirect_to(posts_url(post))         => Location: http://example.com/posts/1
    link_to(post.title, post) # => link_to(post.title, posts_url(post)) => <a href="/posts/1">Hello world</a>

  Any method that calls url_for on its parameters will automatically benefit from this. 

* Removed deprecated parameters_for_method_reference concept (legacy from before named routes) [DHH]

* Add ActionController::Routing::Helpers, a module to contain common URL helpers such as polymorphic_url. [Nicholas Seckar]

* Included the HttpAuthentication plugin as part of core (ActionController::HttpAuthentication::Basic) [DHH]

* Modernize documentation for form helpers. [jeremymcanally]

* Add brief introduction to REST to the resources documentation. [fearoffish]

* Fix various documentation typos throughout ActionPack. [Henrik N]

* Enhance documentation and add examples for url_for. [jeremymcanally]

* Fix documentation typo in routes. [norbert, pam]

* Sweep flash when filter chain is halted. [Caio Chassot <lists@v2studio.com>]

* Fixed that content_tag with a block will just return the result instead of concate it if not used in a ERb view #7857, #7432 [michael.niessner]

* Replace the current block/continuation filter chain handling by an implementation based on a simple loop.  #8226 [Stefan Kaes]

* Update UrlWriter to accept :anchor parameter. Closes #6771. [octopod]

* Added RecordTagHelper for using RecordIdentifier conventions on divs and other container elements [DHH]. Example:

    <% div_for(post) do %>     <div id="post_45" class="post">
      <%= post.body %>           What a wonderful world!
    <% end %>                  </div>

* Added page[record] accessor to JavaScriptGenerator that relies on RecordIdentifier to find the right dom id [DHH]. Example:

    format.js do
      # Calls: new Effect.fade('post_45');
      render(:update) { |page| page[post].visual_effect(:fade) }
    end

* Added RecordIdentifier to enforce view conventions on records for dom ids, classes, and partial paths [DHH]

* Added map.namespace to deal with the common situation of admin sections and the like [DHH]

    Before:
    
      map.resources :products, :path_prefix => "admin", :controller => "admin/products", :collection => { :inventory => :get }, :member => { :duplicate => :post }
      map.resources :tags, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_tags"
      map.resources :images, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_images"
      map.resources :variants, :name_prefix => 'admin_product_', :path_prefix => "admin/products/:product_id", :controller => "admin/product_variants"

    After:
    
      map.namespace(:admin) do |admin|
        admin.resources :products,
          :collection => { :inventory => :get },
          :member     => { :duplicate => :post },
          :has_many   => [ :tags, :images, :variants ]
      end

* Added :name_prefix as standard for nested resources [DHH]. WARNING: May be backwards incompatible with your app

    Before:

      map.resources :emails do |emails|
        emails.resources :comments,    :name_prefix => "email_"
        emails.resources :attachments, :name_prefix => "email_"
      end
      
    After:

      map.resources :emails do |emails|
        emails.resources :comments
        emails.resources :attachments
      end
    
    This does mean that if you intended to have comments_url go to /emails/5/comments, then you'll have to set :name_prefix to nil explicitly.

* Added :has_many and :has_one for declaring plural and singular resources beneath the current [DHH]

    Before:
      
      map.resources :notes do |notes|
        notes.resources :comments
        notes.resources :attachments
        notes.resource :author
      end
    
    After:
    
      map.resources :notes, :has_many => [ :comments, :attachments ], :has_one => :author

* Added that render :xml will try to call to_xml if it can [DHH]. Makes these work:

    render :xml => post
    render :xml => comments

* Added :location option to render so that the common pattern of rendering a response after creating a new resource is now a 1-liner [DHH]

    render :xml => post.to_xml, :status => :created, :location => post_url(post)

* Ensure that render_text only adds string content to the body of the response [DHH]

* Return the string representation from an Xml Builder when rendering a partial. Closes #5044 [tpope] 

* Fixed that parameters from XML should also be presented in a hash with indifferent access [DHH]

* Tweak template format rules so that the ACCEPT header is only used if it's text/javascript.  This is so ajax actions without a :format param get recognized as Mime::JS. [Rick]

* The default respond_to blocks don't set a specific extension anymore, so that both 'show.rjs' and 'show.js.rjs' will work. [Rick]

* Allow layouts with extension of .html.erb.  Closes #8032 [Josh Knowles]

* Change default respond_to templates for xml and rjs formats. [Rick]

  * Default xml template goes from #{action_name}.rxml => #{action_name}.xml.builder.
  * Default rjs template goes from #{action_name}.rjs => #{action_name}.js.rjs.
  
  You can still specify your old templates:
  
    respond_to do |format|
      format.xml do
        render :action => "#{action_name}.rxml"
      end
    end

* Fix WSOD due to modification of a formatted template extension so that requests to templates like 'foo.html.erb' fail on the second hit.  [Rick]

* Fix WSOD when template compilation fails [Rick]

* Change ActionView template defaults.  Look for templates using the request format first, such as "show.html.erb" or "show.xml.builder", before looking for the old defaults like "show.erb" or "show.builder" [Rick]

* Highlight helper highlights one or many terms in a single pass.  [Jeremy Kemper]

* Dropped the use of ; as a separator of non-crud actions on resources and went back to the vanilla slash. It was a neat idea, but lots of the non-crud actions turned out not to be RPC (as the ; was primarily intended to discourage), but legitimate sub-resources, like /parties/recent, which didn't deserve the uglification of /parties;recent. Further more, the semicolon caused issues with caching and HTTP authentication in Safari. Just Not Worth It [DHH]

* Added that FormTagHelper#submit_tag will return to its original state if the submit fails and you're using :disable_with [DHH]

* Cleaned up, corrected, and mildly expanded ActionPack documentation.  Closes #7190 [jeremymcanally]

* Small collection of ActionController documentation cleanups.  Closes #7319 [jeremymcanally]

* Make sure the route expiry hash is constructed by comparing the to_param-ized values of each hash. [Jamis Buck]

* Allow configuration of the default action cache path for #caches_action calls.  [Rick Olson]

  class ListsController < ApplicationController
    caches_action :index, :cache_path => Proc.new { |controller| 
      controller.params[:user_id] ? 
        controller.send(:user_lists_url, c.params[:user_id]) :
        controller.send(:lists_url) }
  end

* Performance: patch cgi/session/pstore to require digest/md5 once rather than per #initialize.  #7583 [Stefan Kaes]

* Cookie session store: ensure that new sessions doesn't reuse data from a deleted session in the same request.  [Jeremy Kemper]

* Deprecation: verification with :redirect_to => :named_route shouldn't be deprecated.  #7525 [Justin French]

* Cookie session store: raise ArgumentError when :session_key is blank.  [Jeremy Kemper]

* Deprecation: remove deprecated request, redirect, and dependency methods. Remove deprecated instance variables. Remove deprecated url_for(:symbol, *args) and redirect_to(:symbol, *args) in favor of named routes. Remove uses_component_template_root for toplevel components directory. Privatize deprecated render_partial and render_partial_collection view methods. Remove deprecated link_to_image, link_image_to, update_element_function, start_form_tag, and end_form_tag helper methods. Remove deprecated human_size helper alias.  [Jeremy Kemper]

* Consistent public/protected/private visibility for chained methods.  #7813 [Dan Manges]

* Prefer MIME constants to strings.  #7707 [Dan Kubb]

* Allow array and hash query parameters. Array route parameters are converted/to/a/path as before.  #6765, #7047, #7462 [bgipsy, Jeremy McAnally, Dan Kubb, brendan]

# Add a #dbman attr_reader for CGI::Session and make CGI::Session::CookieStore#generate_digest public so it's easy to generate digests
using the cookie store's secret. [Rick]

* Added Request#url that returns the complete URL used for the request [DHH]

* Extract dynamic scaffolding into a plugin.  #7700 [Josh Peek]

* Added user/password options for url_for to add http authentication in a URL [DHH]

* Fixed that FormTagHelper#text_area_tag should disregard :size option if it's not a string [Brendon Davidson]

* Set the original button value in an attribute of the button when using the :disable_with key with submit_tag, so that the original can be restored later. [Jamis Buck]

* session_enabled? works with session :off.  #6680 [Catfish]

* Added :port and :host handling to UrlRewriter (which unified url_for usage, regardless of whether it's called in view or controller) #7616 [alancfrancis]

* Allow send_file/send_data to use a registered mime type as the :type parameter #7620 [jonathan]

* Allow routing requirements on map.resource(s) #7633 [quixoten]. Example:

  map.resources :network_interfaces, :requirements => { :id => /^\d+\.\d+\.\d+\.\d+$/ }

* Cookie session store: empty and unchanged sessions don't write a cookie.  [Jeremy Kemper]

* Added helper(:all) as a way to include all helpers from app/helpers/**/*.rb in ApplicationController [DHH]

* Integration tests: introduce methods for other HTTP methods.  #6353 [caboose]

* Routing: better support for escaped values in route segments.  #7544 [Chris
Roos]

* Introduce a cookie-based session store as the Rails default. Sessions typically contain at most a user_id and flash message; both fit within the 4K cookie size limit. A secure message digest is included with the cookie to ensure data integrity (a user cannot alter his user_id without knowing the secret key included in the digest). If you have more than 4K of session data or don't want your data to be visible to the user, pick another session store.  Cookie-based sessions are dramatically faster than the alternatives.   [Jeremy Kemper]

  Example config/environment.rb:
    # Use an application-wide secret key and the default SHA1 message digest.
    config.action_controller.session = { :secret => "can't touch this" }

    # Store a secret key per user and employ a stronger message digest.
    config.action_controller.session = {
      :digest => 'SHA512',
      :secret => Proc.new { User.current.secret_key }
    }

* Added .erb and .builder as preferred aliases to the now deprecated .rhtml and .rxml extensions [Chad Fowler]. This is done to separate the renderer from the mime type. .erb templates are often used to render emails, atom, csv, whatever. So labeling them .rhtml doesn't make too much sense. The same goes for .rxml, which can be used to build everything from HTML to Atom to whatever. .rhtml and .rxml will continue to work until Rails 3.0, though. So this is a slow phasing out. All generators and examples will start using the new aliases, though.

* Added caching option to AssetTagHelper#stylesheet_link_tag and AssetTagHelper#javascript_include_tag [DHH]. Examples:

    stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is false =>
      <link href="/stylesheets/style1.css"  media="screen" rel="Stylesheet" type="text/css" />
      <link href="/stylesheets/styleB.css"  media="screen" rel="Stylesheet" type="text/css" />
      <link href="/stylesheets/styleX2.css" media="screen" rel="Stylesheet" type="text/css" />
 
    stylesheet_link_tag :all, :cache => true # when ActionController::Base.perform_caching is true =>
      <link href="/stylesheets/all.css"  media="screen" rel="Stylesheet" type="text/css" />

  ...when caching is on, all.css is the concatenation of style1.css, styleB.css, and styleX2.css.
  Same deal for JavaScripts.

* Work around the two connection per host browser limit: use asset%d.myapp.com to distribute asset requests among asset[0123].myapp.com. Use a DNS wildcard or CNAMEs to map these hosts to your asset server. See http://www.die.net/musings/page_load_time/ for background.  [Jeremy Kemper]

* Added default mime type for CSS (Mime::CSS) [DHH]

* Added that rendering will automatically insert the etag header on 200 OK responses. The etag is calculated using MD5 of the response body. If a request comes in that has a matching etag, the response will be changed to a 304 Not Modified and the response body will be set to an empty string. [DHH]

* Added X-Runtime to all responses with the request run time [DHH]

* Add Mime::Type convenience methods to check the current mime type. [Rick]

  request.format.html? # => true if Mime::HTML
  request.format.jpg?  # => true if Mime::JPG

  # ActionController sample usage:
  # the session will be disabled for non html/ajax requests
  session :off, :if => Proc.new { |req| !(req.format.html? || req.format.js?) }

* Performance: patch cgi/session to require digest/md5 once rather than per #create_new_id.  [Stefan Kaes]

* Add a :url_based_filename => true option to ActionController::Streaming::send_file, which allows URL-based filenames.  [Thomas Fuchs]

* Fix that FormTagHelper#submit_tag using :disable_with should trigger the onsubmit handler of its form if available [DHH]

* Fix #render_file so that TemplateError is called with the correct params and you don't get the WSOD.  [Rick]

* Fix issue with deprecation messing up #template_root= usage.  Add #prepend_view_path and #append_view_path to allow modification of a copy of the
superclass' view_paths.  [Rick]

* Allow Controllers to have multiple view_paths instead of a single template_root.  Closes #2754 [John Long]

* Add much-needed html-scanner tests.  Fixed CDATA parsing bug. [Rick]

* improve error message for Routing for named routes.  Closes #7346 [Rob Sanheim]

* Added enhanced docs to routing assertions.  Closes #7359 [Rob Sanheim]

* fix form_for example in ActionController::Resources documentation.  Closes #7362 [gnarg]

* Make sure that the string returned by TextHelper#truncate is actually a string, not a char proxy -- that should only be used internally while working on a multibyte-safe way of truncating [DHH]

* Added FormBuilder#submit as a delegate for FormTagHelper#submit_tag [DHH]

* Allow Routes to generate all urls for a set of options by specifying :generate_all => true. Allows caching to properly set or expire all paths for a resource. References #1739. [Nicholas Seckar]

* Change the query parser to map empty GET params to "" rather than nil. Closes #5694. [Nicholas Seckar]

* date_select and datetime_select take a :default option.  #7052 [nik.wakelin]
    date_select "post", "written_on", :default => 3.days.from_now
    date_select "credit_card", "bill_due", :default => { :day => 20 }

* select :multiple => true suffixes the attribute name with [] unless already suffixed.  #6977 [nik.kakelin, ben, julik]

* Improve routes documentation.  #7095 [zackchandler]

* mail_to :encode => 'hex' also encodes the mailto: part of the href attribute as well as the linked email when no name is given.  #2061 [Jarkko Laine, pfc.pille@gmx.net]

* Resource member routes require :id, eliminating the ambiguous overlap with collection routes.  #7229 [dkubb]

* Remove deprecated assertions.  [Jeremy Kemper]

* Change session restoration to allow namespaced models to be autoloaded. Closes #6348. [Nicholas Seckar]

* Fix doubly appearing parameters due to string and symbol mixups. Closes #2551. [aeden]

* Fix overly greedy rescues when loading helpers. Fixes #6268. [Nicholas Seckar]

* Fixed NumberHelper#number_with_delimiter to use "." always for splitting the original number, not the delimiter parameter #7389 [ceefour]

* Autolinking recognizes trailing and embedded . , : ;  #7354 [Jarkko Laine]

* Make TextHelper::auto_link recognize URLs with colons in path correctly, fixes #7268.  [imajes]

* Update to script.aculo.us 1.7.0.  [Thomas Fuchs]

* Modernize cookie testing code, and increase coverage (Heckle++) #7101 [Kevin Clark]

* Improve Test Coverage for ActionController::Routing::Route#matches_controller_and_action? (Heckle++) #7115 [Kevin Clark]

* Heckling ActionController::Resources::Resource revealed that set_prefixes didn't break when :name_prefix was munged. #7081 [Kevin Clark]

* Fix #distance_of_time_in_words to report accurately against the Duration class.  #7114 [eventualbuddha]

* Refactor #form_tag to allow easy extending.  [Rick]

* Update to Prototype 1.5.0. [Sam Stephenson]

* RecordInvalid, RecordNotSaved => 422 Unprocessable Entity, StaleObjectError => 409 Conflict.  #7097 [dkubb]

* Allow fields_for to be nested inside form_for, so that the name and id get properly constructed [Jamis Buck]

* Allow inGroupsOf and eachSlice to be called through rjs. #7046 [Cody Fauser]

* Allow exempt_from_layout :rhtml.  #6742, #7026 [Dan Manges, Squeegy]

* Fix parsing of array[] CGI parameters so extra empty values aren't included.  #6252 [Nicholas Seckar, aiwilliams, brentrowland]

* link_to_unless_current works with full URLs as well as paths.  #6891 [Jarkko Laine, manfred, idrifter]

* Lookup the mime type for #auto_discovery_link_tag in the Mime::Type class.  Closes #6941 [Josh Peek]

* Fix bug where nested resources ignore a parent singleton parent's path prefix.  Closes #6940 [Dan Kubb]

* Fix no method error with error_messages_on.  Closes #6935 [nik.wakelin Koz]

* Slight doc tweak to the ActionView::Helpers::PrototypeHelper#replace docs.  Closes #6922 [Steven Bristol]

* Slight doc tweak to #prepend_filter.  Closes #6493 [Jeremy Voorhis]

* Add more extensive documentation to the AssetTagHelper.  Closes #6452 [Bob Silva]

* Clean up multiple calls to #stringify_keys in TagHelper, add better documentation and testing for TagHelper.  Closes #6394 [Bob Silva]

* [DOCS] fix reference to ActionController::Macros::AutoComplete for #text_field_with_auto_complete. Closes #2578 [Jan Prill]

* Make sure html_document is reset between integration test requests. [ctm]

* Set session to an empty hash if :new_session => false and no session cookie or param is present. CGI::Session was raising an unrescued ArgumentError.  [Josh Susser]

* Routing uses URI escaping for path components and CGI escaping for query parameters.  [darix, Jeremy Kemper]

* Fix assert_redirected_to bug where redirecting from a nested to to a top-level controller incorrectly added the current controller's nesting.  Closes #6128.  [Rick Olson]

* Singleton resources: POST /singleton => create, GET /singleton/new => new.  [Jeremy Kemper]

* Use 400 Bad Request status for unrescued ActiveRecord::RecordInvalid exceptions.  [Jeremy Kemper]

* Silence log_error deprecation warnings from inspecting deprecated instance variables.  [Nate Wiger]

* Only cache GET requests with a 200 OK response.  #6514, #6743 [RSL, anamba]

* Ensure render :json => ... skips the layout.  Closes #6808 [Josh Peek]

* Fix HTML::Node to output double quotes instead of single quotes.  Closes #6845 [mitreandy]

* Correctly report which filter halted the chain.  #6699 [Martin Emde]

* Fix a bug in Routing where a parameter taken from the path of the current request could not be used as a query parameter for the next. Closes #6752. [Nicholas Seckar]

* Unrescued ActiveRecord::RecordNotFound responds with 404 instead of 500.  [Jeremy Kemper]

* Improved auto_link to match more valid urls correctly [Tobias Luetke]

* Add singleton resources. [Rick Olson]

  map.resource :account
  
  GET /account
  GET /account;edit
  UPDATE /account
  DELETE /account

* respond_to recognizes JSON. render :json => @person.to_json automatically sets the content type and takes a :callback option to specify a client-side function to call using the rendered JSON as an argument.  #4185 [Scott Raymond, eventualbuddha]
    # application/json response with body 'Element.show({:name: "David"})'
    respond_to do |format|
      format.json { render :json => { :name => "David" }.to_json, :callback => 'Element.show' }
    end

* Makes :discard_year work without breaking multi-attribute parsing in AR.  #1260, #3800 [sean@ardismg.com, jmartin@desertflood.com, stephen@touset.org, Bob Silva]

* Adds html id attribute to date helper elements.  #1050, #1382 [mortonda@dgrmm.net, David North, Bob Silva]

* Add :index and @auto_index capability to model driven date/time selects.  #847, #2655 [moriq, Doug Fales, Bob Silva]

* Add :order to datetime_select, select_datetime, and select_date.  #1427 [Timothee Peignier, patrick@lenz.sh, Bob Silva]

* Added time_select to work with time values in models. Update scaffolding.  #2489, #2833 [Justin Palmer, Andre Caum, Bob Silva]

* Added :include_seconds to select_datetime, datetime_select and time_select.  #2998 [csn, Bob Silva]

* All date/datetime selects can now accept an array of month names with :use_month_names. Allows for localization.  #363 [tomasj, Bob Silva]

* Adds :time_separator to select_time and :date_separator to select_datetime. Preserves BC.  #3811 [Bob Silva]

* Added map.root as an alias for map.connect '' [DHH]

* Added Request#format to return the format used for the request as a mime type. If no format is specified, the first Request#accepts type is used. This means you can stop using respond_to for anything else than responses [DHH]. Examples:

    GET /posts/5.xml   | request.format => Mime::XML
    GET /posts/5.xhtml | request.format => Mime::HTML
    GET /posts/5       | request.format => request.accepts.first (usually Mime::HTML for browsers)

* Added the option for extension aliases to mime type registration [DHH]. Example (already in the default routes):

    Mime::Type.register "text/html", :html, %w( application/xhtml+xml ), %w( xhtml )
  
  ...will respond on both .html and .xhtml.

* @response.redirect_url works with 201 Created responses: just return headers['Location'] rather than checking the response status.  [Jeremy Kemper]

* Added CSV to Mime::SET so that respond_to csv will work [Cody Fauser]

* Fixed that HEAD should return the proper Content-Length header (that is, actually use @body.size, not just 0) [DHH]

* Added GET-masquarading for HEAD, so request.method will return :get even for HEADs. This will help anyone relying on case request.method to automatically work with HEAD and map.resources will also allow HEADs to all GET actions. Rails automatically throws away the response content in a reply to HEAD, so you don't even need to worry about that. If you, for whatever reason, still need to distinguish between GET and HEAD in some edge case, you can use Request#head? and even Request.headers["REQUEST_METHOD"] for get the "real" answer. Closes #6694 [DHH]

* Update Routing to complain when :controller is not specified by a route. Closes #6669. [Nicholas Seckar]

* Ensure render_to_string cleans up after itself when an exception is raised.  #6658 [Rob Sanheim]

* Extract template_changed_since? from compile_template? so plugins may override its behavior for non-file-based templates.  #6651 [Jeff Barczewski]

* Update to Prototype and script.aculo.us [5579]. [Thomas Fuchs]

* simple_format helper doesn't choke on nil.  #6644 [jerry426]

* Update to Prototype 1.5.0_rc2 [5550] which makes it work in Opera again [Thomas Fuchs]

* Reuse named route helper module between Routing reloads. Use remove_method to delete named route methods after each load. Since the module is never collected, this fixes a significant memory leak. [Nicholas Seckar]

* ActionView::Base.erb_variable accessor names the buffer variable used to render templates. Defaults to _erbout; use _buf for erubis.  [Rick Olson]

* assert_select_rjs :remove.  [Dylan Egan]

* Always clear model associations from session.  #4795 [sd@notso.net, andylien@gmail.com]

* Update to Prototype 1.5.0_rc2. [Sam Stephenson]

* Remove JavaScriptLiteral in favor of ActiveSupport::JSON::Variable. [Sam Stephenson]

* Sync ActionController::StatusCodes::STATUS_CODES with http://www.iana.org/assignments/http-status-codes.  #6586 [dkubb]

* Multipart form values may have a content type without being treated as uploaded files if they do not provide a filename.  #6401 [Andreas Schwarz, Jeremy Kemper]

* assert_response supports symbolic status codes.  #6569 [Kevin Clark]
    assert_response :ok
    assert_response :not_found
    assert_response :forbidden

* Cache parsed query parameters.  #6559 [Stefan Kaes]

* Deprecate JavaScriptHelper#update_element_function, which is superseeded by RJS [Thomas Fuchs]

* pluralize helper interprets nil as zero.  #6474 [pope]

* Fix invalid test fixture exposed by stricter Ruby 1.8.5 multipart parsing.  #6524 [Bob Silva]

* Set ActionView::Base.default_form_builder once rather than passing the :builder option to every form or overriding the form helper methods.  [Jeremy Kemper]

* Deprecate expire_matched_fragments. Use expire_fragment instead.  #6535 [Bob Silva]

* Update to latest Prototype, which doesn't serialize disabled form elements, adds clone() to arrays, empty/non-string Element.update() and adds a fixes excessive error reporting in WebKit beta versions [Thomas Fuchs]

* Deprecate start_form_tag and end_form_tag.  Use form_tag / '</form>' from now on.  [Rick]

* Added block-usage to PrototypeHelper#form_remote_tag, document block-usage of FormTagHelper#form_tag [Rick]

* Add a 0 margin/padding div around the hidden _method input tag that form_tag outputs.  [Rick]

* Added block-usage to TagHelper#content_tag [DHH]. Example:

   <% content_tag :div, :class => "strong" %>
     Hello world!
   <% end %>
  
  Will output:
    <div class="strong">Hello world!</div>

* Deprecated UrlHelper#link_to_image and UrlHelper#link_to :post => true #6409 [BobSilva]

* Upgraded NumberHelper with number_to_phone support international formats to comply with ITU E.123 by supporting area codes with less than 3 digits, added precision argument to number_to_human_size (defaults to 1) #6421 [BobSilva]

* Fixed that setting RAILS_ASSET_ID to "" should not add a trailing slash after assets #6454 [BobSilva/chrismear]

* Force *_url named routes to show the host in ActionView [Rick]

  <%= url_for ... %> # no host
  <%= foo_path %>    # no host
  <%= foo_url %>     # host!

* Add support for converting blocks into function arguments to JavaScriptGenerator#call and JavaScriptProxy#call. [Sam Stephenson]

* Add JavaScriptGenerator#literal for wrapping a string in an object whose #to_json is the string itself. [Sam Stephenson]

* Add <%= escape_once html %> to escape html while leaving any currently escaped entities alone.  Fix button_to double-escaping issue. [Rick]

* Fix double-escaped entities, such as &amp;amp;, &amp;#123;, etc. [Rick]

* Fix deprecation warnings when rendering the template error template. [Nicholas Seckar]

* Fix routing to correctly determine when generation fails. Closes #6300. [psross].

* Fix broken assert_generates when extra keys are being checked. [Jamis Buck]

* Replace KCODE checks with String#chars for truncate.  Closes #6385 [Manfred Stienstra]

* Make page caching respect the format of the resource that is being requested even if the current route is the default route so that, e.g. posts.rss is not transformed by url_for to '/' and subsequently cached as '/index.html' when it should be cached as '/posts.rss'.  [Marcel Molina Jr.]

* Use String#chars in TextHelper::excerpt. Closes #6386 [Manfred Stienstra]

* Install named routes into ActionView::Base instead of proxying them to the view via helper_method. Closes #5932. [Nicholas Seckar]

* Update to latest Prototype and script.aculo.us trunk versions [Thomas Fuchs]

* Fix relative URL root matching problems. [Mark Imbriaco]

* Fix filter skipping in controller subclasses.  #5949, #6297, #6299 [Martin Emde]

* render_text may optionally append to the response body. render_javascript appends by default. This allows you to chain multiple render :update calls by setting @performed_render = false between them (awaiting a better public API).  [Jeremy Kemper]

* Rename test assertion to prevent shadowing. Closes #6306. [psross]

* Fixed that NumberHelper#number_to_delimiter should respect precision of higher than two digits #6231 [phallstrom]

* Fixed that FormHelper#radio_button didn't respect an :id being passed in #6266 [evansj]

* Added an html_options hash parameter to javascript_tag() and update_page_tag() helpers #6311 [tzaharia]. Example:

    update_page_tag :defer => 'true' { |page| ... }

  Gives:

    <script defer="true" type="text/javascript">...</script>
    
  Which is needed for dealing with the IE6 DOM when it's not yet fully loaded.

* Fixed that rescue template path shouldn't be hardcoded, then it's easier to hook in your own #6295 [mnaberez]

* Fixed escaping of backslashes in JavaScriptHelper#escape_javascript #6302 [sven@c3d2.de]

* Fixed that some 500 rescues would cause 500's themselves because the response had not yet been generated #6329 [cmselmer]

* respond_to :html doesn't assume .rhtml.  #6281 [Hampton Catlin]

* Fixed some deprecation warnings in ActionPack [Rick Olson]

* assert_select_rjs decodes escaped unicode chars since the Javascript generators encode them.  #6240 [japgolly]

* Deprecation: @cookies, @headers, @request, @response will be removed after 1.2. Use the corresponding method instead.  [Jeremy Kemper]

* Make the :status parameter expand to the default message for that status code if it is an integer. Also support symbol statuses. [Jamis Buck]. Examples:

    head :status => 404        # expands to "404 Not Found"
    head :status => :not_found # expands to "404 Not Found"
    head :status => :created   # expands to "201 Created"

* Add head(options = {}) for responses that have no body. [Jamis Buck]. Examples:

    head :status => 404 # return an empty response with a 404 status
    head :location => person_path(@person), :status => 201

* Fix bug that kept any before_filter except the first one from being able to halt the before_filter chain.  [Rick Olson]

* strip_links is case-insensitive.  #6285 [tagoh, Bob Silva]

* Clear the cache of possible controllers whenever Routes are reloaded. [Nicholas Seckar]

* Filters overhaul including meantime filter support using around filters + blocks.  #5949 [Martin Emde, Roman Le Negrate, Stefan Kaes, Jeremy Kemper]

* Update RJS render tests. [sam]

* Update CGI process to allow sessions to contain namespaced models. Closes #4638. [dfelstead@site5.com]

* Fix routing to respect user provided requirements and defaults when assigning default routing options (such as :action => 'index'). Closes #5950. [Nicholas Seckar]

* Rescue Errno::ECONNRESET to handle an unexpectedly closed socket connection. Improves SCGI reliability.  #3368, #6226 [sdsykes, fhanshaw@vesaria.com]

* Added that respond_to blocks will automatically set the content type to be the same as is requested [DHH]. Examples:

    respond_to do |format|
      format.html { render :text => "I'm being sent as text/html" }
      format.rss  { render :text => "I'm being sent as application/rss+xml" }
      format.atom { render :text => "I'm being sent as application/xml", :content_type => Mime::XML }
    end

* Added utf-8 as the default charset for all renders. You can change this default using ActionController::Base.default_charset=(encoding) [DHH]

* Added proper getters and setters for content type and charset [DHH]. Example of what we used to do:

    response.headers["Content-Type"] = "application/atom+xml; charset=utf-8"
  
  ...now:
  
    response.content_type = Mime::ATOM
    response.charset      = "utf-8"

      page['test1'].replace "<div id=\"1\">foo</div>"
      page['test2'].replace_html "<div id=\"2\">foo</div>"

    Test it with...

      assert_select_rjs :chained_replace

* Update UrlWriter to support :only_path. [Nicholas Seckar, Dave Thomas]

* Fixed JavaScriptHelper#link_to_function and JavaScriptHelper#button_to_function to have the script argument be optional [DHH]. So what used to require a nil, like this:

    link_to("Hider", nil, :class => "hider_link") { |p| p[:something].hide }
  
  ...can be written like this:

    link_to("Hider", :class => "hider_link") { |p| p[:something].hide }

* Update to script.aculo.us 1.6.3 [Thomas Fuchs]

* Update to Prototype 1.5.0_rc1 [sam]

* Tighten rescue clauses.  #5985 [james@grayproductions.net]

* Fix send_data documentation typo.  #5982 [brad@madriska.com]

* Switch to using FormEncodedPairParser for parsing request parameters. [Nicholas Seckar, DHH]

* respond_to .html now always renders #{action_name}.rhtml so that registered custom template handlers do not override it in priority. Custom mime types require a block and throw proper error now. [Tobias Luetke]

* Deprecation: test deprecated instance vars in partials. [Jeremy Kemper]

* Add UrlWriter to allow writing urls from Mailers and scripts. [Nicholas Seckar]

* Clean up and run the Active Record integration tests by default.  #5854 [kevin.clark@gmail.com, Jeremy Kemper]

* Add support for the param_name parameter to the auto_complete_field helper. #5026 [david.a.williams@gmail.com]

* Deprecation! @params, @session, @flash will be removed after 1.2. Use the corresponding instance methods instead. You'll get printed warnings during tests and logged warnings in dev mode when you access either instance variable directly. [Jeremy Kemper]

* Make Routing noisy when an anchor regexp is assigned to a segment. #5674 [francois.beausoleil@gmail.com]

* Added months and years to the resolution of DateHelper#distance_of_time_in_words, such that "60 days ago" becomes "2 months ago" #5611 [pjhyett@gmail.com]

* Make controller_path available as an instance method.  #5724 [jmckible@gmail.com]

* Update query parser to support adjacent hashes. [Nicholas Seckar]

* Make action caching aware of different formats for the same action so that, e.g.  foo.xml is cached separately from foo.html. Implicitly set content type when reading in cached content with mime revealing extensions so the entire onous isn't on the webserver. [Marcel Molina Jr.]

* Restrict Request Method hacking with ?_method to POST requests.  [Rick Olson]

* Fix bug when passing multiple options to SimplyRestful, like :new => { :preview => :get, :draft => :get }.  [Rick Olson, Josh Susser, Lars Pind]

* Added exception handling of missing layouts #5373 [chris@ozmm.org]

* Fixed that real files and symlinks should be treated the same when compiling templates #5438 [zachary@panandscan.com]

* Fixed that the flash should be reset when reset_session is called #5584 [shugo@ruby-lang.org]

* Added special case for "1 Byte" in NumberHelper#number_to_human_size #5593 [murpyh@rubychan.de]

* Add route_name_path method to generate only the path for a named routes. For example, map.person will add person_path. [Nicholas Seckar]

* Avoid naming collision among compiled view methods. [Jeremy Kemper]

* Fix CGI extensions when they expect string but get nil in Windows. Closes #5276 [mislav@nippur.irb.hr]

* Determine the correct template_root for deeply nested components.  #2841 [s.brink@web.de]

* Fix strip_links so that it doesn't hang on multiline <acronym> tags [Jamis Buck]

* Remove problematic control chars in rescue template. #5316 [Stefan Kaes]

* Make sure passed routing options are not mutated by routing code. #5314 [Blair Zajac]

* Make sure changing the controller from foo/bar to bing/bang does not change relative to foo. [Jamis Buck]

* Escape the path before routing recognition. #3671

* Make sure :id and friends are unescaped properly. #5275 [me@julik.nl]

* Fix documentation for with_routing to reflect new reality. #5281 [rramdas@gmail.com]

* Rewind readable CGI params so others may reread them (such as CGI::Session when passing the session id in a multipart form).  #210 [mklame@atxeu.com, matthew@walker.wattle.id.au]

* Added Mime::TEXT (text/plain) and Mime::ICS (text/calendar) as new default types [DHH]

* Added Mime::Type.register(string, symbol, synonyms = []) for adding new custom mime types [DHH]. Example: Mime::Type.register("image/gif", :gif)

* Added support for Mime objects in render :content_type option [DHH]. Example: render :text => some_atom, :content_type => Mime::ATOM

* Add :status option to send_data and send_file. Defaults to '200 OK'.  #5243 [Manfred Stienstra <m.stienstra@fngtps.com>]

* Routing rewrite. Simpler, faster, easier to understand. The published API for config/routes.rb is unchanged, but nearly everything else is different, so expect breakage in plugins and libs that try to fiddle with routes. [Nicholas Seckar, Jamis Buck]

  map.connect '/foo/:id', :controller => '...', :action => '...'
  map.connect '/foo/:id.:format', :controller => '...', :action => '...'
  map.connect '/foo/:id', ..., :conditions => { :method => :get }

* Cope with missing content type and length headers. Parse parameters from multipart and urlencoded request bodies only. [Jeremy Kemper]

* Accept multipart PUT parameters. #5235 [guy.naor@famundo.com]

* Added interrogation of params[:format] to determine Accept type. If :format is specified and matches a declared extension, like "rss" or "xml", that mime type will be put in front of the accept handler. This means you can link to the same action from different extensions and use that fact to determine output [DHH]. Example:

  class WeblogController < ActionController::Base
    def index
      @posts = Post.find :all
      
      respond_to do |format|
        format.html
        format.xml { render :xml => @posts.to_xml }
        format.rss { render :action => "feed.rxml" }
      end
    end
  end
  
  # returns HTML when requested by a browser, since the browser
  # has the HTML mimetype at the top of its priority list
  Accept: text/html
  GET /weblog 
  
  # returns the XML 
  Accept: application/xml
  GET /weblog 

  # returns the HTML 
  Accept: application/xml
  GET /weblog.html

  # returns the XML
  Accept: text/html
  GET /weblog.xml
  
  All this relies on the fact that you have a route that includes .:format.
  
* Expanded :method option in FormTagHelper#form_tag, FormHelper#form_for, PrototypeHelper#remote_form_for, PrototypeHelper#remote_form_tag, and PrototypeHelper#link_to_remote to allow for verbs other than GET and POST by automatically creating a hidden form field named _method, which will simulate the other verbs over post [DHH]

* Added :method option to UrlHelper#link_to, which allows for using other verbs than GET for the link. This replaces the :post option, which is now deprecated. Example: link_to "Destroy", person_url(:id => person), :method => :delete [DHH]

* follow_redirect doesn't complain about being redirected to the same controller. #5153 [dymo@mk.ukrtelecom.ua]

* Add layout attribute to response object with the name of the layout that was rendered, or nil if none rendered. [Kevin Clark kevin.clark@gmail.com]

* Fix NoMethodError when parsing params like &&. [Adam Greenfield]

* Fix flip flopped logic in docs for url_for's :only_path option. Closes #4998. [esad@esse.at]

* form.text_area handles the :size option just like the original text_area (:size => '60x10' becomes cols="60" rows="10").  [Jeremy Kemper]

* Excise ingrown code from FormOptionsHelper#options_for_select. #5008 [anonymous]

* Small fix in routing to allow dynamic routes (broken after [4242]) [Rick]

    map.connect '*path', :controller => 'files', :action => 'show'

* Replace alias method chaining with Module#alias_method_chain. [Marcel Molina Jr.]

* Replace Ruby's deprecated append_features in favor of included. [Marcel Molina Jr.]

* Use #flush between switching from #write to #syswrite. Closes #4907. [Blair Zajac <blair@orcaware.com>]

* Documentation fix: integration test scripts don't require integration_test. Closes #4914. [Frederick Ros <sl33p3r@free.fr>]

* ActionController::Base Summary documentation rewrite. Closes #4900. [kevin.clark@gmail.com]

* Fix text_helper.rb documentation rendering. Closes #4725. [Frederick Ros]

* Fixes bad rendering of JavaScriptMacrosHelper rdoc (closes #4910) [Frederick Ros]

* Allow error_messages_for to report errors for multiple objects, as well as support for customizing the name of the object in the error summary header. Closes #4186. [andrew@redlinesoftware.com, Marcel Molina Jr.]
  
  error_messages_for :account, :user, :subscription, :object_name => :account

* Enhance documentation for setting headers in integration tests. Skip auto HTTP prepending when its already there. Closes #4079. [Rick Olson]

* Documentation for AbstractRequest. Closes #4895. [kevin.clark@gmail.com]

* Update layout and content_for documentation to use yield rather than magic @content_for instance variables. [Marcel Molina Jr.]

* Fix assert_redirected_to tests according to real-world usage.  Also, don't fail if you add an extra :controller option: [Rick]

    redirect_to :action => 'new'
    assert_redirected_to :controller => 'monkeys', :action => 'new'

* Cache CgiRequest#request_parameters so that multiple calls don't re-parse multipart data. [Rick]

* Diff compared routing options.  Allow #assert_recognizes to take a second arg as a hash to specify optional request method [Rick]

    assert_recognizes({:controller => 'users', :action => 'index'}, 'users')
    assert_recognizes({:controller => 'users', :action => 'create'}, {:path => 'users', :method => :post})

* Diff compared options with #assert_redirected_to [Rick]

* Add support in routes for semicolon delimited "subpaths", like /books/:id;:action [Jamis Buck]

* Change link_to_function and button_to_function to (optionally) take an update_page block instead of a JavaScript string. Closes #4804. [zraii@comcast.net, Sam Stephenson]

* Fixed that remote_form_for can leave out the object parameter and default to the instance variable of the object_name, just like form_for [DHH]

* Modify routing so that you can say :require => { :method => :post } for a route, and the route will never be selected unless the request method is POST. Only works for route recognition, not for route generation. [Jamis Buck]

* Added :add_headers option to verify which merges a hash of name/value pairs into the response's headers hash if the prerequisites cannot be satisfied. [Sam Stephenson]
  ex. verify :only => :speak, :method => :post, 
             :render => { :status => 405, :text => "Must be post" }, 
             :add_headers => { "Allow" => "POST" }

* Added ActionController.filter_parameter_logging that makes it easy to remove passwords, credit card numbers, and other sensitive information from being logged when a request is handled #1897 [jeremye@bsa.ca.gov]

* Slight doc tweak to #prepend_filter.  Closes #6493 [Jeremy Voorhis]

* Add more extensive documentation to the AssetTagHelper.  Closes #6452 [Bob Silva]

* Clean up multiple calls to #stringify_keys in TagHelper, add better documentation and testing for TagHelper.  Closes #6394 [Bob Silva]

* [DOCS] fix reference to ActionController::Macros::AutoComplete for #text_field_with_auto_complete. Closes #2578 [Jan Prill]

* Make sure html_document is reset between integration test requests. [ctm]

* Set session to an empty hash if :new_session => false and no session cookie or param is present. CGI::Session was raising an unrescued ArgumentError.  [Josh Susser]

* Fix assert_redirected_to bug where redirecting from a nested to to a top-level controller incorrectly added the current controller's nesting.  Closes #6128.  [Rick Olson]

* Ensure render :json => ... skips the layout.  #6808 [Josh Peek]

* Silence log_error deprecation warnings from inspecting deprecated instance variables.  [Nate Wiger]

* Only cache GET requests with a 200 OK response.  #6514, #6743 [RSL, anamba]

* Correctly report which filter halted the chain.  #6699 [Martin Emde]

* respond_to recognizes JSON. render :json => @person.to_json automatically sets the content type and takes a :callback option to specify a client-side function to call using the rendered JSON as an argument.  #4185 [Scott Raymond, eventualbuddha]
    # application/json response with body 'Element.show({:name: "David"})'
    respond_to do |format|
      format.json { render :json => { :name => "David" }.to_json, :callback => 'Element.show' }
    end

* Makes :discard_year work without breaking multi-attribute parsing in AR.  #1260, #3800 [sean@ardismg.com, jmartin@desertflood.com, stephen@touset.org, Bob Silva]

* Adds html id attribute to date helper elements.  #1050, #1382 [mortonda@dgrmm.net, David North, Bob Silva]

* All date/datetime selects can now accept an array of month names with :use_month_names. Allows for localization.  #363 [tomasj, Bob Silva]

* Adds :time_separator to select_time and :date_separator to select_datetime. Preserves BC.  #3811 [Bob Silva]

* @response.redirect_url works with 201 Created responses: just return headers['Location'] rather than checking the response status.  [Jeremy Kemper]

* Fixed that HEAD should return the proper Content-Length header (that is, actually use @body.size, not just 0) [DHH]

* Added GET-masquarading for HEAD, so request.method will return :get even for HEADs. This will help anyone relying on case request.method to automatically work with HEAD and map.resources will also allow HEADs to all GET actions. Rails automatically throws away the response content in a reply to HEAD, so you don't even need to worry about that. If you, for whatever reason, still need to distinguish between GET and HEAD in some edge case, you can use Request#head? and even Request.headers["REQUEST_METHOD"] for get the "real" answer. Closes #6694 [DHH]


*1.13.0 RC1* (r5619, November 22nd, 2006)

* Update to Prototype and script.aculo.us [5579]. [Sam Stephenson, Thomas Fuchs]

* simple_format helper doesn't choke on nil.  #6644 [jerry426]

* Deprecate standalone components.  [Jeremy Kemper]

* Always clear model associations from session.  #4795 [sd@notso.net, andylien@gmail.com]

* Remove JavaScriptLiteral in favor of ActiveSupport::JSON::Variable. [Sam Stephenson]

* Sync ActionController::StatusCodes::STATUS_CODES with http://www.iana.org/assignments/http-status-codes.  #6586 [dkubb]

    assert_response :ok
    assert_response :not_found
    assert_response :forbidden

* Fix invalid test fixture exposed by stricter Ruby 1.8.5 multipart parsing.  #6524 [Bob Silva]

* Set ActionView::Base.default_form_builder once rather than passing the :builder option to every form or overriding the form helper methods.  [Jeremy Kemper]

* Deprecate expire_matched_fragments. Use expire_fragment instead.  #6535 [Bob Silva]

* Deprecate start_form_tag and end_form_tag.  Use form_tag / '</form>' from now on.  [Rick]

* Added block-usage to PrototypeHelper#form_remote_tag, document block-usage of FormTagHelper#form_tag [Rick]

* Add a 0 margin/padding div around the hidden _method input tag that form_tag outputs.  [Rick]

* Added block-usage to TagHelper#content_tag [DHH]. Example:

   <% content_tag :div, :class => "strong" %>
     Hello world!
   <% end %>
  
  Will output:
    <div class="strong">Hello world!</div>

* Deprecated UrlHelper#link_to_image and UrlHelper#link_to :post => true #6409 [BobSilva]

* Upgraded NumberHelper with number_to_phone support international formats to comply with ITU E.123 by supporting area codes with less than 3 digits, added precision argument to number_to_human_size (defaults to 1) #6421 [BobSilva]

* Fixed that setting RAILS_ASSET_ID to "" should not add a trailing slash after assets #6454 [BobSilva/chrismear]

* Force *_url named routes to show the host in ActionView [Rick]

  <%= url_for ... %> # no host
  <%= foo_path %>    # no host
  <%= foo_url %>     # host!

* Add support for converting blocks into function arguments to JavaScriptGenerator#call and JavaScriptProxy#call. [Sam Stephenson]

* Add JavaScriptGenerator#literal for wrapping a string in an object whose #to_json is the string itself. [Sam Stephenson]

* Add <%= escape_once html %> to escape html while leaving any currently escaped entities alone.  Fix button_to double-escaping issue. [Rick]

* Fix double-escaped entities, such as &amp;amp;, &amp;#123;, etc. [Rick]

* Fix routing to correctly determine when generation fails. Closes #6300. [psross].

* Fix broken assert_generates when extra keys are being checked. [Jamis Buck]

* Replace KCODE checks with String#chars for truncate.  Closes #6385 [Manfred Stienstra]

* Make page caching respect the format of the resource that is being requested even if the current route is the default route so that, e.g. posts.rss is not transformed by url_for to '/' and subsequently cached as '/index.html' when it should be cached as '/posts.rss'.  [Marcel Molina Jr.]

* Use String#chars in TextHelper::excerpt. Closes #6386 [Manfred Stienstra]

* Fix relative URL root matching problems. [Mark Imbriaco]

* Fix filter skipping in controller subclasses.  #5949, #6297, #6299 [Martin Emde]

* render_text may optionally append to the response body. render_javascript appends by default. This allows you to chain multiple render :update calls by setting @performed_render = false between them (awaiting a better public API).  [Jeremy Kemper]

* Rename test assertion to prevent shadowing. Closes #6306. [psross]

* Fixed that NumberHelper#number_to_delimiter should respect precision of higher than two digits #6231 [phallstrom]

* Fixed that FormHelper#radio_button didn't respect an :id being passed in #6266 [evansj]

* Added an html_options hash parameter to javascript_tag() and update_page_tag() helpers #6311 [tzaharia]. Example:

    update_page_tag :defer => 'true' { |page| ... }

  Gives:

    <script defer="true" type="text/javascript">...</script>
    
  Which is needed for dealing with the IE6 DOM when it's not yet fully loaded.

* Fixed that rescue template path shouldn't be hardcoded, then it's easier to hook in your own #6295 [mnaberez]

* Fixed escaping of backslashes in JavaScriptHelper#escape_javascript #6302 [sven@c3d2.de]

* Fixed that some 500 rescues would cause 500's themselves because the response had not yet been generated #6329 [cmselmer]

* respond_to :html doesn't assume .rhtml.  #6281 [Hampton Catlin]

* Fixed some deprecation warnings in ActionPack [Rick Olson]

* assert_select_rjs decodes escaped unicode chars since the Javascript generators encode them.  #6240 [japgolly]

* Deprecation: @cookies, @headers, @request, @response will be removed after 1.2. Use the corresponding method instead.  [Jeremy Kemper]

* Make the :status parameter expand to the default message for that status code if it is an integer. Also support symbol statuses. [Jamis Buck]. Examples:

    head :status => 404        # expands to "404 Not Found"
    head :status => :not_found # expands to "404 Not Found"
    head :status => :created   # expands to "201 Created"

* Add head(options = {}) for responses that have no body. [Jamis Buck]. Examples:

    head :status => 404 # return an empty response with a 404 status
    head :location => person_path(@person), :status => 201

* Fix bug that kept any before_filter except the first one from being able to halt the before_filter chain.  [Rick Olson]

* strip_links is case-insensitive.  #6285 [tagoh, Bob Silva]

* Clear the cache of possible controllers whenever Routes are reloaded. [Nicholas Seckar]

* Filters overhaul including meantime filter support using around filters + blocks.  #5949 [Martin Emde, Roman Le Negrate, Stefan Kaes, Jeremy Kemper]

* Update CGI process to allow sessions to contain namespaced models. Closes #4638. [dfelstead@site5.com]

* Fix routing to respect user provided requirements and defaults when assigning default routing options (such as :action => 'index'). Closes #5950. [Nicholas Seckar]

* Rescue Errno::ECONNRESET to handle an unexpectedly closed socket connection. Improves SCGI reliability.  #3368, #6226 [sdsykes, fhanshaw@vesaria.com]

* Added that respond_to blocks will automatically set the content type to be the same as is requested [DHH]. Examples:

    respond_to do |format|
      format.html { render :text => "I'm being sent as text/html" }
      format.rss  { render :text => "I'm being sent as application/rss+xml" }
      format.atom { render :text => "I'm being sent as application/xml", :content_type => Mime::XML }
    end

* Added utf-8 as the default charset for all renders. You can change this default using ActionController::Base.default_charset=(encoding) [DHH]

* Added proper getters and setters for content type and charset [DHH]. Example of what we used to do:

    response.headers["Content-Type"] = "application/atom+xml; charset=utf-8"
  
  ...now:
  
    response.content_type = Mime::ATOM
    response.charset      = "utf-8"

* Declare file extensions exempt from layouts.  #6219 [brandon]
    Example: ActionController::Base.exempt_from_layout 'rpdf'

* Add chained replace/update support for assert_select_rjs [Rick Olson]

    Given RJS like...

      page['test1'].replace "<div id=\"1\">foo</div>"
      page['test2'].replace_html "<div id=\"2\">foo</div>"

    Test it with...

      assert_select_rjs :chained_replace
      assert_select_rjs :chained_replace, "test1"

      assert_select_rjs :chained_replace_html
      assert_select_rjs :chained_replace_html, "test2"

* Load helpers in alphabetical order for consistency. Resolve cyclic javascript_helper dependency.  #6132, #6178 [choonkeat@gmail.com]

* Skip params with empty names, such as the &=Save query string from <input type="submit"/>.  #2569 [manfred, raphinou@yahoo.com]

* Fix assert_tag so that :content => "foo" does not match substrings, but only exact strings. Use :content => /foo/ to match substrings. #2799 [Eric Hodel]

* Update JavaScriptGenerator#show/hide/toggle/remove to new Prototype syntax for multiple ids,  #6068 [petermichaux@gmail.com]

* Update UrlWriter to support :only_path. [Nicholas Seckar, Dave Thomas]

* Fixed JavaScriptHelper#link_to_function and JavaScriptHelper#button_to_function to have the script argument be optional [DHH]. So what used to require a nil, like this:

    link_to("Hider", nil, :class => "hider_link") { |p| p[:something].hide }
  
  ...can be written like this:

    link_to("Hider", :class => "hider_link") { |p| p[:something].hide }

* Added access to nested attributes in RJS #4548 [richcollins@gmail.com]. Examples:

    page['foo']['style']                  # => $('foo').style;
    page['foo']['style']['color']         # => $('blank_slate').style.color;
    page['foo']['style']['color'] = 'red' # => $('blank_slate').style.color = 'red';
    page['foo']['style'].color = 'red'    # => $('blank_slate').style.color = 'red';

* Fixed that AssetTagHelper#image_tag and others using compute_public_path should not modify the incoming source argument (closes #5102) [eule@space.ch]

* Deprecated the auto-appending of .png to AssetTagHelper#image_tag calls that doesn't have an extension [DHH] 

* Fixed FormOptionsHelper#select to respect :selected value #5813

* Fixed TextHelper#simple_format to deal with multiple single returns within a single paragraph #5835 [moriq@moriq.com]

* Fixed TextHelper#pluralize to handle 1 as a string #5909 [rails@bencurtis.com]

* Improved resolution of DateHelper#distance_of_time_in_words for better precision #5994 [Bob Silva]

* Changed that uncaught exceptions raised any where in the application will cause RAILS_ROOT/public/500.html to be read and shown instead of just the static "Application error (Rails)" [DHH]

* Added deprecation language for pagination which will become a plugin by Rails 2.0 [DHH]

* Added deprecation language for in_place_editor and auto_complete_field that both pieces will become plugins by Rails 2.0 [DHH]

* Deprecated all of ActionController::Dependencies. All dependency loading is now handled from Active Support [DHH]

* Added assert_select* for CSS selector-based testing (deprecates assert_tag) #5936 [assaf.arkin@gmail.com]

* radio_button_tag generates unique id attributes.  #3353 [Bob Silva, somekool@gmail.com]

* strip_tags passes through blank args such as nil or "".  #2229, #6702 [duncan@whomwah.com, dharana]

* Cleanup assert_tag :children counting.  #2181 [jamie@bravenet.com]

* button_to accepts :method so you can PUT and DELETE with it.  #6005 [Dan Webb]

* Update sanitize text helper to strip plaintext tags, and <img src="javascript:bang">.  [Rick Olson]

* Add routing tests to assert that RoutingError is raised when conditions aren't met.  Closes #6016 [Nathan Witmer]

* Make auto_link parse a greater subset of valid url formats. [Jamis Buck]

* Integration tests: headers beginning with X aren't excluded from the HTTP_ prefix, so X-Requested-With becomes HTTP_X_REQUESTED_WITH as expected. [Mike Clark]

* Switch to using FormEncodedPairParser for parsing request parameters. [Nicholas Seckar, DHH]

* respond_to .html now always renders #{action_name}.rhtml so that registered custom template handlers do not override it in priority. Custom mime types require a block and throw proper error now. [Tobias Luetke]

* Deprecation: test deprecated instance vars in partials. [Jeremy Kemper]

* Add UrlWriter to allow writing urls from Mailers and scripts. [Nicholas Seckar]

* Relax Routing's anchor pattern warning; it was preventing use of [^/] inside restrictions. [Nicholas Seckar]

* Add controller_paths variable to Routing. [Nicholas Seckar]

* Fix assert_redirected_to issue with named routes for module controllers.  [Rick Olson]

* Tweak RoutingError message to show option diffs, not just missing named route significant keys. [Rick Olson]

* Invoke method_missing directly on hidden actions. Closes #3030. [Nicholas Seckar]

* Add RoutingError exception when RouteSet fails to generate a path from a Named Route. [Rick Olson]

* Replace Reloadable with Reloadable::Deprecated. [Nicholas Seckar]

* Deprecation: check whether instance variables have been monkeyed with before assigning them to deprecation proxies. Raises a RuntimeError if so. [Jeremy Kemper]

* Add support for the param_name parameter to the auto_complete_field helper. #5026 [david.a.williams@gmail.com]

* Deprecation! @params, @session, @flash will be removed after 1.2. Use the corresponding instance methods instead. You'll get printed warnings during tests and logged warnings in dev mode when you access either instance variable directly. [Jeremy Kemper]

* Make Routing noisy when an anchor regexp is assigned to a segment. #5674 [francois.beausoleil@gmail.com]

* Added months and years to the resolution of DateHelper#distance_of_time_in_words, such that "60 days ago" becomes "2 months ago" #5611 [pjhyett@gmail.com]

* Make controller_path available as an instance method.  #5724 [jmckible@gmail.com]

* Update query parser to support adjacent hashes. [Nicholas Seckar]

* Make action caching aware of different formats for the same action so that, e.g.  foo.xml is cached separately from foo.html. Implicitly set content type when reading in cached content with mime revealing extensions so the entire onous isn't on the webserver. [Marcel Molina Jr.]

* Restrict Request Method hacking with ?_method to POST requests.  [Rick Olson]

* Fixed the new_#{resource}_url route and added named route tests for Simply Restful.  [Rick Olson]

* Added map.resources from the Simply Restful plugin [DHH]. Examples (the API has changed to use plurals!):

    map.resources :messages
    map.resources :messages, :comments
    map.resources :messages, :new => { :preview => :post }

* Fixed that integration simulation of XHRs should set Accept header as well [Edward Frederick]

* TestRequest#reset_session should restore a TestSession, not a hash [Koz]

* Don't search a load-path of '.' for controller files [Jamis Buck]

* Update integration.rb to require test_process explicitly instead of via Dependencies. [Nicholas Seckar]

* Fixed that you can still access the flash after the flash has been reset in reset_session.  Closes #5584 [lmarlow@yahoo.com]

* Allow form_for and fields_for to work with indexed form inputs.  [Jeremy Kemper, Matt Lyon]

  <% form_for 'post[]', @post do |f| -%>
  <% end -%>

* Remove leak in development mode by replacing define_method with module_eval. [Nicholas Seckar]

* Provide support for decimal columns to form helpers. Closes #5672. [dave@pragprog.com]

* Pass :id => nil or :class => nil to error_messages_for to supress that html attribute. #3586 [olivier_ansaldi@yahoo.com, sebastien@goetzilla.info]

* Reset @html_document between requests so assert_tag works. #4810 [jarkko@jlaine.net, easleydp@gmail.com]

* Integration tests behave well with render_component. #4632 [edward.frederick@revolution.com, dev.rubyonrails@maxdunn.com]

* Added exception handling of missing layouts #5373 [chris@ozmm.org]

* Fixed that real files and symlinks should be treated the same when compiling templates #5438 [zachary@panandscan.com]

* Fixed that the flash should be reset when reset_session is called #5584 [shugo@ruby-lang.org]

* Added special case for "1 Byte" in NumberHelper#number_to_human_size #5593 [murpyh@rubychan.de]

* Fixed proper form-encoded parameter parsing for requests with "Content-Type: application/x-www-form-urlencoded; charset=utf-8" (note the presence of a charset directive) [DHH]

* Add route_name_path method to generate only the path for a named routes. For example, map.person will add person_path. [Nicholas Seckar]

* Avoid naming collision among compiled view methods. [Jeremy Kemper]

* Fix CGI extensions when they expect string but get nil in Windows. Closes #5276 [mislav@nippur.irb.hr]

* Determine the correct template_root for deeply nested components.  #2841 [s.brink@web.de]

* Fix that routes with *path segments in the recall can generate URLs. [Rick]

* Fix strip_links so that it doesn't hang on multiline <acronym> tags [Jamis Buck]

* Remove problematic control chars in rescue template. #5316 [Stefan Kaes]

* Make sure passed routing options are not mutated by routing code. #5314 [Blair Zajac]

* Make sure changing the controller from foo/bar to bing/bang does not change relative to foo. [Jamis Buck]

* Escape the path before routing recognition. #3671

* Make sure :id and friends are unescaped properly. #5275 [me@julik.nl]

* Rewind readable CGI params so others may reread them (such as CGI::Session when passing the session id in a multipart form).  #210 [mklame@atxeu.com, matthew@walker.wattle.id.au]

* Added Mime::TEXT (text/plain) and Mime::ICS (text/calendar) as new default types [DHH]

* Added Mime::Type.register(string, symbol, synonyms = []) for adding new custom mime types [DHH]. Example: Mime::Type.register("image/gif", :gif)

* Added support for Mime objects in render :content_type option [DHH]. Example: render :text => some_atom, :content_type => Mime::ATOM

* Add :status option to send_data and send_file. Defaults to '200 OK'.  #5243 [Manfred Stienstra <m.stienstra@fngtps.com>]

* Routing rewrite. Simpler, faster, easier to understand. The published API for config/routes.rb is unchanged, but nearly everything else is different, so expect breakage in plugins and libs that try to fiddle with routes. [Nicholas Seckar, Jamis Buck]

  map.connect '/foo/:id', :controller => '...', :action => '...'
  map.connect '/foo/:id.:format', :controller => '...', :action => '...'
  map.connect '/foo/:id', ..., :conditions => { :method => :get }

* Cope with missing content type and length headers. Parse parameters from multipart and urlencoded request bodies only. [Jeremy Kemper]

* Accept multipart PUT parameters. #5235 [guy.naor@famundo.com]

* Added interrogation of params[:format] to determine Accept type. If :format is specified and matches a declared extension, like "rss" or "xml", that mime type will be put in front of the accept handler. This means you can link to the same action from different extensions and use that fact to determine output [DHH]. Example:

  class WeblogController < ActionController::Base
    def index
      @posts = Post.find :all
      
      respond_to do |format|
        format.html
        format.xml { render :xml => @posts.to_xml }
        format.rss { render :action => "feed.rxml" }
      end
    end
  end
  
  # returns HTML when requested by a browser, since the browser
  # has the HTML mimetype at the top of its priority list
  Accept: text/html
  GET /weblog 
  
  # returns the XML 
  Accept: application/xml
  GET /weblog 

  # returns the HTML 
  Accept: application/xml
  GET /weblog.html

  # returns the XML
  Accept: text/html
  GET /weblog.xml
  
  All this relies on the fact that you have a route that includes .:format.
  
* Expanded :method option in FormTagHelper#form_tag, FormHelper#form_for, PrototypeHelper#remote_form_for, PrototypeHelper#remote_form_tag, and PrototypeHelper#link_to_remote to allow for verbs other than GET and POST by automatically creating a hidden form field named _method, which will simulate the other verbs over post [DHH]

* Added :method option to UrlHelper#link_to, which allows for using other verbs than GET for the link. This replaces the :post option, which is now deprecated. Example: link_to "Destroy", person_url(:id => person), :method => :delete [DHH]

* follow_redirect doesn't complain about being redirected to the same controller. #5153 [dymo@mk.ukrtelecom.ua]

* Add layout attribute to response object with the name of the layout that was rendered, or nil if none rendered. [Kevin Clark kevin.clark@gmail.com]

* Fix NoMethodError when parsing params like &&. [Adam Greenfield]

* form.text_area handles the :size option just like the original text_area (:size => '60x10' becomes cols="60" rows="10").  [Jeremy Kemper]

* Excise ingrown code from FormOptionsHelper#options_for_select. #5008 [anonymous]

* Small fix in routing to allow dynamic routes (broken after [4242]) [Rick]

    map.connect '*path', :controller => 'files', :action => 'show'

* Use #flush between switching from #write to #syswrite. Closes #4907. [Blair Zajac <blair@orcaware.com>]

* Allow error_messages_for to report errors for multiple objects, as well as support for customizing the name of the object in the error summary header. Closes #4186. [andrew@redlinesoftware.com, Marcel Molina Jr.]
  
  error_messages_for :account, :user, :subscription, :object_name => :account

* Fix assert_redirected_to tests according to real-world usage.  Also, don't fail if you add an extra :controller option: [Rick]

    redirect_to :action => 'new'
    assert_redirected_to :controller => 'monkeys', :action => 'new'

* Diff compared routing options.  Allow #assert_recognizes to take a second arg as a hash to specify optional request method [Rick]

    assert_recognizes({:controller => 'users', :action => 'index'}, 'users')
    assert_recognizes({:controller => 'users', :action => 'create'}, {:path => 'users', :method => :post})

* Diff compared options with #assert_redirected_to [Rick]

* Add support in routes for semicolon delimited "subpaths", like /books/:id;:action [Jamis Buck]

* Change link_to_function and button_to_function to (optionally) take an update_page block instead of a JavaScript string. Closes #4804. [zraii@comcast.net, Sam Stephenson]

* Modify routing so that you can say :require => { :method => :post } for a route, and the route will never be selected unless the request method is POST. Only works for route recognition, not for route generation. [Jamis Buck]

* Added :add_headers option to verify which merges a hash of name/value pairs into the response's headers hash if the prerequisites cannot be satisfied. [Sam Stephenson]
  ex. verify :only => :speak, :method => :post, 
             :render => { :status => 405, :text => "Must be post" }, 
             :add_headers => { "Allow" => "POST" }


*1.12.5* (August 10th, 2006)

* Updated security fix


*1.12.4* (August 8th, 2006)

* Cache CgiRequest#request_parameters so that multiple calls don't re-parse multipart data. [Rick]

* Fixed that remote_form_for can leave out the object parameter and default to the instance variable of the object_name, just like form_for [DHH]

* Added ActionController.filter_parameter_logging that makes it easy to remove passwords, credit card numbers, and other sensitive information from being logged when a request is handled.  #1897 [jeremye@bsa.ca.gov]

* Fixed that real files and symlinks should be treated the same when compiling templates.  #5438 [zachary@panandscan.com]

* Add :status option to send_data and send_file. Defaults to '200 OK'.  #5243 [Manfred Stienstra <m.stienstra@fngtps.com>]

* Update documentation for erb trim syntax. #5651 [matt@mattmargolis.net]

* Short documentation to mention use of Mime::Type.register. #5710 [choonkeat@gmail.com]


*1.12.3* (June 28th, 2006)

* Fix broken traverse_to_controller. We now:
  Look for a _controller.rb file under RAILS_ROOT to load.
  If we find it, we require_dependency it and return the controller it defined. (If none was defined we stop looking.)
  If we don't find it, we look for a .rb file under RAILS_ROOT to load. If we find it, and it loads a constant we keep looking.
  Otherwise we check to see if a directory of the same name exists, and if it does we create a module for it.


*1.12.2* (June 27th, 2006)

* Refinement to avoid exceptions in traverse_to_controller.

* (Hackish) Fix loading of arbitrary files in Ruby's load path by traverse_to_controller. [Nicholas Seckar]


*1.12.1* (April 6th, 2006)

* Fixed that template extensions would be cached development mode #4624 [Stefan Kaes]

* Update to Prototype 1.5.0_rc0 [Sam Stephenson]

* Honor skipping filters conditionally for only certain actions even when the parent class sets that filter to conditionally be executed only for the same actions. #4522 [Marcel Molina Jr.]

* Delegate xml_http_request in integration tests to the session instance. [Jamis Buck]

* Update the diagnostics template skip the useless '<controller not set>' text. [Nicholas Seckar]

* CHANGED DEFAULT: Don't parse YAML input by default, but keep it available as an easy option [DHH]

* Add additional autocompleter options [aballai, Thomas Fuchs]

* Fixed fragment caching of binary data on Windows #4493 [bellis@deepthought.org]

* Applied Prototype $() performance patches (#4465, #4477) and updated script.aculo.us [Sam Stephenson, Thomas Fuchs]

* Added automated timestamping to AssetTagHelper methods for stylesheets, javascripts, and images when Action Controller is run under Rails [DHH]. Example:

    image_tag("rails.png") # => '<img alt="Rails" src="/images/rails.png?1143664135" />'
  
  ...to avoid frequent stats (not a problem for most people), you can set RAILS_ASSET_ID in the ENV to avoid stats:

    ENV["RAILS_ASSET_ID"] = "2345"
    image_tag("rails.png") # => '<img alt="Rails" src="/images/rails.png?2345" />'

  This can be used by deployment managers to set the asset id by application revision


*1.12.0* (March 27th, 2006)

* Add documentation for respond_to. [Jamis Buck]

* Fixed require of bluecloth and redcloth when gems haven't been loaded #4446 [murphy@cYcnus.de]

* Update to Prototype 1.5.0_pre1 [Sam Stephenson]

* Change #form_for and #fields_for so that the second argument is not required [Dave Thomas]

    <% form_for :post, @post, :url => { :action => 'create' } do |f| -%>
    
  becomes...
  
    <% form_for :post, :url => { :action => 'create' } do |f| -%>

* Update to script.aculo.us 1.6 [Thomas Fuchs]

* Enable application/x-yaml processing by default [Jamis Buck]

* Fix double url escaping of remote_function. Add :escape => false option to ActionView's url_for. [Nicholas Seckar]

* Add :script option to in_place_editor to support evalScripts (closes #4194) [codyfauser@gmail.com]

* Fix mixed case enumerable methods in the JavaScript Collection Proxy (closes #4314) [codyfauser@gmail.com]

* Undo accidental escaping for mail_to; add regression test. [Nicholas Seckar]

* Added nicer message for assert_redirected_to (closes #4294) [court3nay]

    assert_redirected_to :action => 'other_host', :only_path => false
    
  when it was expecting...
  
    redirected_to :action => 'other_host', :only_path => true, :host => 'other.test.host'
  
  gives the error message...

    response is not a redirection to all of the options supplied (redirection is <{:only_path=>false, :host=>"other.test.host", :action=>"other_host"}>), difference: <{:only_path=>"true", :host=>"other.test.host"}>

* Change url_for to escape the resulting URLs when called from a view. [Nicholas Seckar, coffee2code]

* Added easy support for testing file uploads with fixture_file_upload #4105 [turnip@turnipspatch.com]. Example:

    # Looks in Test::Unit::TestCase.fixture_path + '/files/spongebob.png'
    post :change_avatar, :avatar => fixture_file_upload('/files/spongebob.png', 'image/png')

* Fixed UrlHelper#current_page? to behave even when url-escaped entities are present #3929 [jeremy@planetargon.com]

* Add ability for relative_url_root to be specified via an environment variable RAILS_RELATIVE_URL_ROOT. [isaac@reuben.com, Nicholas Seckar]

* Fixed link_to "somewhere", :post => true to produce valid XHTML by using the parentnode instead of document.body for the instant form #3007 [Bob Silva]

* Added :function option to PrototypeHelper#observe_field/observe_form that allows you to call a function instead of submitting an ajax call as the trigger #4268 [jonathan@daikini.com]

* Make Mime::Type.parse consider q values (if any) [Jamis Buck]

* XML-formatted requests are typecast according to "type" attributes for :xml_simple [Jamis Buck]

* Added protection against proxy setups treating requests as local even when they're not #3898 [stephen_purcell@yahoo.com]

* Added TestRequest#raw_post that simulate raw_post from CgiRequest #3042 [francois.beausoleil@gmail.com]

* Underscore dasherized keys in formatted requests [Jamis Buck]

* Add MimeResponds::Responder#any for managing multiple types with identical responses [Jamis Buck]

* Make the xml_http_request testing method set the HTTP_ACCEPT header [Jamis Buck]

* Add Verification to scaffolds.   Prevent destructive actions using GET [Michael Koziarski]

* Avoid hitting the filesystem when using layouts by using a File.directory? cache. [Stefan Kaes, Nicholas Seckar]

* Simplify ActionController::Base#controller_path [Nicholas Seckar]

* Added simple alert() notifications for RJS exceptions when config.action_view.debug_rjs = true. [Sam Stephenson]

* Added :content_type option to render, so you can change the content type on the fly [DHH]. Example: render :action => "atom.rxml", :content_type => "application/atom+xml"

* CHANGED DEFAULT: The default content type for .rxml is now application/xml instead of type/xml, see http://www.xml.com/pub/a/2004/07/21/dive.html for reason [DHH]

* Added option to render action/template/file of a specific extension (and here by template type). This means you can have multiple templates with the same name but a different extension [DHH]. Example:
  
    class WeblogController < ActionController::Base
      def index
        @posts = Post.find :all
  
        respond_to do |type|
          type.html # using defaults, which will render weblog/index.rhtml
          type.xml  { render :action => "index.rxml" }
          type.js   { render :action => "index.rjs" }
        end
      end
    end

* Added better support for using the same actions to output for different sources depending on the Accept header [DHH]. Example:

    class WeblogController < ActionController::Base
      def create
        @post = Post.create(params[:post])
      
        respond_to do |type|
          type.js   { render }  # renders create.rjs
          type.html { redirect_to :action => "index" }
          type.xml  do
            headers["Location"] = url_for(:action => "show", :id => @post)
            render(:nothing, :status => "201 Created")
          end
        end
      end
    end

* Added Base#render(:xml => xml) that works just like Base#render(:text => text), but sets the content-type to text/xml and the charset to UTF-8 [DHH]

* Integration test's url_for now runs in the context of the last request (if any) so after post /products/show/1 url_for :action => 'new' will yield /product/new  [Tobias Luetke]

* Re-added mixed-in helper methods for the JavascriptGenerator.  Moved JavascriptGenerators methods to a module that is mixed in after the helpers are added.  Also fixed that variables set in the enumeration methods like #collect are set correctly.  Documentation added for the enumeration methods [Rick Olson].  Examples:

    page.select('#items li').collect('items') do |element|
      element.hide
    end
    # => var items = $$('#items li').collect(function(value, index) { return value.hide(); });

* Added plugin support for parameter parsers, which allows for better support for REST web services. By default, posts submitted with the application/xml content type is handled by creating a XmlSimple hash with the same name as the root element of the submitted xml. More handlers can easily be registered like this:

    # Assign a new param parser to a new content type
    ActionController::Base.param_parsers['application/atom+xml'] = Proc.new do |data| 
      node = REXML::Document.new(post) 
     { node.root.name => node.root }
    end

    # Assign the default XmlSimple to a new content type
    ActionController::Base.param_parsers['application/backpack+xml'] = :xml_simple
 
Default YAML web services were retired, ActionController::Base.param_parsers carries an example which shows how to get this functionality back. As part of this new plugin support, request.[formatted_post?, xml_post?, yaml_post? and post_format] were all deprecated in favor of request.content_type [Tobias Luetke]

* Added element and collection proxies to RJS [DHH]. Examples:

    page['blank_slate']                  # => $('blank_slate');
    page['blank_slate'].show             # => $('blank_slate').show();
    page['blank_slate'].show('first').up # => $('blank_slate').show('first').up();
    
    page.select('p')                      # => $$('p');

  module ApplicationHelper
    def update_time
      page.replace_html 'time', Time.now.to_s(:db)
      page.visual_effect :highlight, 'time'

    First name: <%= f.text_field :first_name %>
    Last name : <%= f.text_field :last_name %>

    Last name : <%= person_form.text_field :last_name %>
    
    <% fields_for :permission => person.permission do |permission_fields| %>
      Admin?  : <%= permission_fields.check_box :admin %>
    <% end %>
  <% end %>

* The auto_link text helper accepts an optional block to format the link text for each url and email address.  Example: auto_link(post.body) { |text| truncate(text, 10) }  [Jeremy Kemper]

* assert_tag uses exact matches for string conditions, instead of partial matches. Use regex to do partial matches. #2799 [Jamis Buck]

* CGI::Session::ActiveRecordStore.data_column_name = 'foobar' to use a different session data column than the 'data' default.  [nbpwie102@sneakemail.com]

    class WeblogController < ApplicationController
      # will run the :authenticate filter

      # will not run the :authenticate filter
      skip_before_filter :authenticate
    end

* Added redirect_to :back as a short-hand for redirect_to(request.env["HTTP_REFERER"]) [DHH]

* Fixed JavascriptHelper#auto_complete_for to only include unique items #2153 [Thomas Fuchs]

* Fixed all AssetHelper methods to work with relative paths, such that javascript_include_tag('stdlib/standard') will look in /javascripts/stdlib/standard instead of '/stdlib/standard/' #1963

* Avoid extending view instance with helper modules each request. Closes #1979

* Performance improvements to CGI methods. Closes #1980 [Skaes]

* Added :post option to UrlHelper#link_to that makes it possible to do POST requests through normal ahref links using Javascript

* Updated vendor copy of html-scanner to support better xml parsing

* Added :popup option to UrlHelper#link_to #1996 [gabriel.gironda@gmail.com]. Examples:

    link_to "Help", { :action => "help" }, :popup => true
    link_to "Busy loop", { :action => "busy" }, :popup => ['new_window', 'height=300,width=600']

* Drop trailing \000 if present on RAW_POST_DATA (works around bug in Safari Ajax implementation) #918

* Fix observe_field to fall back to event-based observation if frequency <= 0 #1916 [michael@schubert.cx]

* Allow use of the :with option for submit_to_remote #1936 [jon@instance-design.co.uk]

* AbstractRequest#domain returns nil when host is an ip address #2012 [kevin.clark@gmail.com]

* ActionController documentation update #2051 [fbeausoleil@ftml.net]

* Make rendering an empty partial collection behave like :nothing => true #2080 [Sam Stephenson]

* Add option to specify the singular name used by pagination.

* Use string key to obtain action value. Allows indifferent hashes to be disabled.

* Added ActionView::Base.cache_template_loading back.

* Rewrote compiled templates to decrease code complexity. Removed template load caching in favour of compiled caching. Fixed template error messages. [Nicholas Seckar]

* Fix Routing to handle :some_param => nil better. [Nicholas Seckar, Luminas]

* Add support for :include with pagination (subject to existing constraints for :include with :limit and :offset) #1478 [michael@schubert.cx]

* Prevent the benchmark module from blowing up if a non-HTTP/1.1 request is processed

* Added :use_short_month option to select_month helper to show month names as abbreviations

* Make link_to escape the javascript in the confirm option #1964 [nicolas.pouillard@gmail.com]

* Make assert_redirected_to properly check URL's passed as strings #1910 [Scott Barron]

* Make sure :layout => false is always used when rendering inside a layout

* Use raise instead of assert_not_nil in Test::Unit::TestCase#process to ensure that the test variables (controller, request, response) have been set

* Make sure assigns are built for every request when testing #1866

* Allow remote_addr to be queried on TestRequest #1668

* Fixed bug when a partial render was passing a local with the same name as the partial

* Improved performance of test app req/sec with ~10% refactoring the render method #1823 [Stefan Kaes]

* Improved performance of test app req/sec with 5-30% through a series of Action Pack optimizations #1811 [Stefan Kaes]

* Changed caching/expiration/hit to report using the DEBUG log level and errors to use the ERROR log level instead of both using INFO

* Added support for per-action session management #1763

* Improved rendering speed on complicated templates by up to 100% (the more complex the templates, the higher the speedup) #1234 [Stephan Kaes]. This did necessasitate a change to the internals of ActionView#render_template that now has four parameters. Developers of custom view handlers (like Amrita) need to update for that.

* Added options hash as third argument to FormHelper#input, so you can do input('person', 'zip', :size=>10) #1719 [jeremye@bsa.ca.gov]

* Added Base#expires_in(seconds)/Base#expires_now to control HTTP content cache headers #1755 [Thomas Fuchs]

* Fixed line number reporting for Builder template errors #1753 [piotr]

* Fixed assert_routing so that testing controllers in modules works as expected [Nicholas Seckar, Rick Olson]

* Fixed bug with :success/:failure callbacks for the JavaScriptHelper methods #1730 [court3nay/Thomas Fuchs]

* Added named_route method to RouteSet instances so that RouteSet instance methods do not prevent certain names from being used. [Nicholas Seckar]

* Fixed routes so that routes which do not specify :action in the path or in the requirements have a default of :action => 'index', In addition, fixed url generation so that :action => 'index' does not need to be provided for such urls. [Nicholas Seckar, Markjuh]

* Worked around a Safari bug where it wouldn't pass headers through if the response was zero length by having render :nothing return ' ' instead of ''

* Fixed Request#subdomains to handle "foo.foo.com" correctly


*1.9.1* (11 July, 2005)

* Fixed that auto_complete_for didn't force the input string to lower case even as the db comparison was

* Fixed that Action View should always use the included Builder, never attempt to require the gem, to ensure compatibility

* Added that nil options are not included in tags, so tag("p", :ignore => nil) now returns <p /> not <p ignore="" />  but that tag("p", :ignore => "") still includes it #1465 [michael@schuerig.de]

* Fixed that UrlHelper#link_to_unless/link_to_if used html_escape on the name if no link was to be applied. This is unnecessary and breaks its use with images #1649 [joergd@pobox.com]

* Improved error message for DoubleRenderError

* Fixed routing to allow for testing of *path components #1650 [Nicholas Seckar]

* Added :handle as an option to sortable_element to restrict the drag handle to a given class #1642 [thejohnny]

* Added a bunch of script.aculo.us features #1644, #1677, #1695 [Thomas Fuchs]
  * Effect.ScrollTo, to smoothly scroll the page to an element
  * Better Firefox flickering handling on SlideUp/SlideDown
  * Removed a possible memory leak in IE with draggables
  * Added support for cancelling dragging my hitting ESC
  * Added capability to remove draggables/droppables and redeclare sortables in dragdrop.js (this makes it possible to call sortable_element on the same element more than once, e.g. in AJAX returns that modify the sortable element. all current sortable 'stuff' on the element will be discarded and the sortable will be rebuilt)
  * Always reset background color on Effect.Highlight; this make change backwards-compatibility, to be sure include style="background-color:(target-color)" on your elements or else elements will fall back to their CSS rules (which is a good thing in most circumstances)
  * Removed circular references from element to prevent memory leaks (still not completely gone in IE)
  * Changes to class extension in effects.js
  * Make Effect.Highlight restore any previously set background color when finishing (makes effect work with CSS classes that set a background color)
  * Fixed myriads of memory leaks in IE and Gecko-based browsers [David Zülke]
  * Added incremental and local autocompleting and loads of documentation to controls.js [Ivan Krstic]
  * Extended the auto_complete_field helper to accept tokens option
  * Changed object extension mechanism to favor Object.extend to make script.aculo.us easily adaptable to support 3rd party libs like IE7.js [David Zülke]
  
* Fixed that named routes didn't use the default values for action and possible other parameters #1534 [Nicholas Seckar]

* Fixed JavascriptHelper#visual_effect to use camelize such that :blind_up will work #1639 [pelletierm@eastmedia.net]

* Fixed that a SessionRestoreError was thrown if a model object was placed in the session that wasn't available to all controllers. This means that it's no longer necessary to use the 'model :post' work-around in ApplicationController to have a Post model in your session.


*1.9.0* (6 July, 2005)

* Added logging of the request URI in the benchmark statement (makes it easy to grep for slow actions)

* Added javascript_include_tag :defaults shortcut that'll include all the default javascripts included with Action Pack (prototype, effects, controls, dragdrop)

* Cache several controller variables that are expensive to calculate #1229 [skaes@web.de]

* The session class backing CGI::Session::ActiveRecordStore may be replaced with any class that duck-types with a subset of Active Record.  See docs for details #1238 [skaes@web.de]

* Fixed that hashes was not working properly when passed by GET to lighttpd #849 [Nicholas Seckar]

* Fixed assert_template nil will be true when no template was rendered #1565 [maceywj@telus.net]

* Added :prompt option to FormOptions#select (and the users of it, like FormOptions#select_country etc) to create "Please select" style descriptors #1181 [Michael Schuerig]

* Added JavascriptHelper#update_element_function, which returns a Javascript function (or expression) that'll update a DOM element according to the options passed #933 [mortonda@dgrmm.net]. Examples:

    <%= update_element_function("products", :action => :insert, :position => :bottom, :content => "<p>New product!</p>") %>

    <% update_element_function("products", :action => :replace, :binding => binding) do %>
      <p>Product 1</p>
      <p>Product 2</p>
    <% end %>

* Added :field_name option to DateHelper#select_(year|month|day) to deviate from the year/month/day defaults #1266 [Marcel Molina]

* Added JavascriptHelper#draggable_element and JavascriptHelper#drop_receiving_element to facilitate easy dragging and dropping through the script.aculo.us libraries #1578 [Thomas Fuchs]

* Added that UrlHelper#mail_to will now also encode the default link title #749 [f.svehla@gmail.com]

* Removed the default option of wrap=virtual on FormHelper#text_area to ensure XHTML compatibility #1300 [thomas@columbus.rr.com]

* Adds the ability to include XML CDATA tags using Builder #1563 [Josh Knowles]. Example:

    xml.cdata! "some text" # => <![CDATA[some text]]>

* Added evaluation of <SCRIPT> blocks in content returned to Ajax calls #1577 [Thomas Fuchs/court3nay/Sean Treadway]

* Directly generate paths with a leading slash instead of tacking it on later.  #1543 [Nicholas Seckar]

* Fixed errant parameter modification in functional tests.  #1542 [Nicholas Seckar]

* Routes fail with leading slash #1540 [Nicholas Seckar]

* Added support for graceful error handling of Ajax calls #1217 [Jamis Buck/Thomas Fuchs]. Example:

    link_to_remote(
      "test", 
      :url => { :action => "faulty" }, 
      :update => { :success => "good", :failure => "bad" },
      403 => "alert('Forbidden- got ya!')",
      404 => "alert('Nothing there...?')", 
      :failure => "alert('Unkown error ' + request.status)")
  
* Attempt to explicitly flush the output at the end of CgiProcess#out

* Fixed assert_redirected_to to handle absolute controller paths properly #1472 [Rick Olson/Nicholas Seckar]

* Added event-based observations when frequency is not set on observe_field/form #1474 [flash@vanklinkenbergsoftware.nl]

* Added script.aculo.us Javascripts (controls.js, dragdrop.js, effects.js) (NEEDS MORE DESCRIPTION) #1509 [Thomas Fuchs]

* Fixed prototype to consider all fields it doesn't know as text (such as Safari's search) just like the browser in its serialization #1497 [Sean Treadway]

* Improved performance of Routes generation by a factor of 5 #1434 [Nicholas Seckar] 

* Added named routes (NEEDS BETTER DESCRIPTION) #1434 [Nicholas Seckar]

* Improved AbstractRequest documentation #1483 [court3nay@gmail.com]

* Added ActionController::Base.allow_concurrency to control whether the application is thread-safe, so multi-threaded servers like WEBrick knows whether to apply a mutex around the performance of each action. Turned off by default. EXPERIMENTAL FEATURE.

* Added TextHelper#word_wrap(text, line_length = 80) #1449 [tuxie@dekadance.se]

* Added a fall-through action for form_remote_tag that'll be used in case Javascript is unavailable #1459 [Scott Barron]. Example:

    form_remote_tag :html => { :action => url_for(:controller => "some", :action => "place") }

* Added :xhr => true/false option to verify so you can ensure that a request is coming from an Ajax call or not #1464 [Thomas Fuchs]

* Added tag_options as a third parameter to AssetHelper#auto_discovery_link_tag to control options like the title of the link #1430 [kevin.clark@gmail.com]

* Added option to pass in parameters to CaptureHelper#capture, so you can create more advanced view helper methods #1466 [duane.johnson@gmail.com]. Example:

    <% show_calendar(:year => 2005, :month => 6) do |day, options| %>
      <% options[:bgcolor] = '#dfd' if 10..15.include? day %>
      [<%= day %>]
    <% end %>

* Changed the default name of the input tag generated by FormTagHelper#submit_tag from "submit" to "commit" so it doesn't clash with form.submit() calls in Javascript #1271

* Fixed relative urls support for lighttpd #1048 [Nicholas Seckar/maznawak@nerim.net]

* Correct distance_of_time_in_words for integer arguments and make the second arg optional, treating the first arg as a duration in seconds.  #1458 [madrobby <thomas@fesch.at>]

* Fixed query parser to deal gracefully with equal signs inside keys and values #1345 [gorou]. 
  Example: /?sig=abcdef=:foobar=&x=y will pass now. 

* Added Cuba to country list #1351 [todd]

* Fixed radio_button to work with numeric values #1352 [demetrius]

* Added :extension option to NumberHelper#number_to_phone #1361 [delynnb]

* Added button_to as a form-based solution to deal with harmful actions that should be hidden behind POSTs. This makes it just as easy as link_to to create a safe trigger for actions like destroy, although it's limited by being a block element, the fixed look, and a no-no inside other forms. #1371 [tom@moertel.com]

* Fixed image_tag so an exception is not thrown just because the image is missing and alt value can't be generated #1395 [Marcel]

* Added a third parameter to TextHelper#auto_link called href_options for specifying additional tag options on the links generated #1401 [tyler.kovacs@gmail.com]. Example: auto_link(text, :all, { :target => "_blank" }) to have all the generated links open in a new window.

* Fixed TextHelper#highlight to return the text, not nil, if the phrase is blank #1409 [patrick@lenz.sh]

* Fixed TagHelper such that :name and 'name' keys in the options doesn't result in two attributes #1455 [take_tk]

* Ensure that helpers are only available to the controllers where they are defined and their subclasses.  #1394 [kdole@tamu.edu]

* render("foo/bar") works with a layout again 

* Fixed double-singularization on scaffolded pagination call (Address would be turned into Addres) #1216, #1404 [nilsga]

* Removed the require hack used by functional testing to work around an earlier bug in rake.

* Allow distance_of_time_in_words to work with any value that responds to #to_time (like dates) #969

* Support :render option for :verify #1440 [TobiasLuetke]

* Updated vendor copy of html-scanner lib to 0.5.2, for bug fixes and optimizations. The :content option may be used as expected--to find a tag whose textual content is a particular value--in assert_tag, now.

* Changed test requests to come from 0.0.0.0 instead of 127.0.0.1 such that they don't trigger debugging screens on exceptions, but instead call rescue_action_in_public

* Modernize scaffolding to match the generator: use the new render method and change style from the warty @params["id"] to the sleek params[:id].  #1367

* Include :id in the action generated by the form helper method.  Then, for example, the controller can do Model.find(params[:id]) for both edit and update actions.  Updated scaffolding to take advantage.  #1367

* Add assertions with friendly messages to TestCase#process to ensure that @controller, @request, and @response are set.  #1367

* Arrays, hashes sent via multipart posts are converted to strings #1032 [dj@omelia.org, me@julik.nl]

* render(:layout => true) is a synonym for render(:layout => nil)

* Make sure the benchmarking render method always returns the output of the render.

* render(:action), render(:template) and render() are the only three calls that default to using a layout. All other render calls assume :layout => false. This also fixes send_file, which was applying a layout if one existed for the current action.

* verify with :redirect_to won't redirect if a redirect or render has already been performed #1350

* render(:partial => true) is identical to the behavior of the deprecated render_partial()

* Fixed render(:partial => "...") to use an empty Hash for the local assigns #1365

* Fixed Caching::Fragments::FileStore.delete to not raise an exception if the delete fails.

* Deprecated all render_* methods in favor of consolidating all rendering behavior in Base#render(options). This enables more natural use of combining options, such as layouts. Examples:

    +---------------------------------------------------------------+-------------------------------------------------------+
    | BEFORE                                                        | AFTER                                                 |
    +---------------------------------------------------------------+-------------------------------------------------------+
    | render_with_layout "weblog/show", "200 OK", "layouts/dialog"  | render :action => "show", :layout => "dialog"         |
    | render_without_layout "weblog/show"                           | render :action => "show", :layout => false            |
    | render_action "error", "404 Not Found"                        | render :action => "error", :status => "404 Not Found" |
    | render_template "xml.div('stuff')", "200 OK", :rxml           | render :inline => "xml.div('stuff')", :type => :rxml  |
    | render_text "hello world!"                                    | render :text => "hello world!"                        |
    | render_partial_collection "person", @people, nil, :a => 1     | render :partial => "person", :collection => @people,  |
    |                                                               |        :locals => { :a => 1 }                         |
    +---------------------------------------------------------------+-------------------------------------------------------+      

* Deprecated redirect_to_path and redirect_to_url in favor of letting redirect_to do the right thing when passed either a path or url.

* Fixed use of an integer as return code for renders, so render_text "hello world", 404 now works #1327

* Fixed assert_redirect_to to work with redirect_to_path #869 [Nicholas Seckar]

* Fixed escaping of :method option in remote_form_tag #1218 [Rick Olson]

* Added Serbia and Montenegro to the country_select #1239 [todd@robotcoop.com]

* Fixed Request#remote_ip in testing #1251 [Jeremy Kemper]

* Fixed that compute_public_path should recognize external URLs, so image_tag("http://www.example.com/images/icon.gif") is not prefixed with the relative url path #1254 [victor-ronr-trac@carotena.net]

* Added support for descending year values in DateHelper#select_year, like select_year(Date.today, :start_year => 2005, :end_year => 1900), which would count down from 2005 to 1900 instead of the other way #1274 [nwoods@mail.com]

* Fixed that FormHelper#checkbox should return a checked checkbox if the value is the same as checked_value #1286 [Florian Weber]

* Fixed Form.disable in Prototype #1317 [Wintermute]

* Added accessors to logger, params, response, session, flash, and headers from the view, so you can write <% logger.info "stuff" %> instead of <% @logger.info "others" %> -- more consistent with the preferred way of accessing these attributes and collections from the controller

* Added support for POST data in form of YAML or XML, which is controller through the Content-Type header. Example request:

    Content-Type: application/xml
    <request><item><content>HelloWorld</content></item></request>
  
  ...is the same as:

    Content-Type: application/x-yaml
    ---
    item:
      content: HelloWorld

  ...is the same as:
  
    item[content]=HelloWorld
  
  Which in the end turns into { "item" => { "content" => "HelloWorld" } }. This makes it a lot easier to publish REST web services on top of your regular actions (as they won't care).
  
  Example Curl call:

    curl -H 'Content-Type: application/xml' -d '<request><item><content>KillMeMore</content></item></request>' http://www.example.com/service

  You can query to find out whether a given request came through as one of these types with:
    - request.post_format? (:url_encoded, :xml or :yaml)
    - request.formatted_post? (for either xml or yaml)
    - request.xml_post?
    - request.yaml_post?

* Added bundling of XmlSimple by Maik Schmidt

* Fixed that render_partial_collection should always return a string (and not sometimes an array, despite <%= %> not caring)

* Added TextHelper#sanitize that can will remove any Javascript handlers, blocks, and forms from an input of HTML.  This allows for use of HTML on public sites, but still be free of XSS issues. #1277 [Jamis Buck]

* Fixed the HTML scanner used by assert_tag where a infinite loop could be caused by a stray less-than sign in the input #1270 [Jamis Buck]

* Added functionality to assert_tag, so you can now do tests on the siblings of a node, to assert that some element comes before or after the element in question, or just to assert that some element exists as a sibling #1226 [Jamis Buck]

* Added better error handling for regexp caching expiration

* Fixed handling of requests coming from unknown HTTP methods not to kill the server

* Added that both AssetHelper#stylesheet_link_tag and AssetHelper#javascript_include_tag now accept an option hash as the last parameter, so you can do stuff like: stylesheet_link_tag "style", :media => "all"

* Added FormTagHelper#image_submit_tag for making submit buttons that uses images

* Added ActionController::Base.asset_host that will then be used by all the asset helpers. This enables you to easily offload static content like javascripts and images to a separate server tuned just for that.

* Fixed action/fragment caching using the filestore when a directory and a file wanted to use the same name. Now there's a .cache prefix that sidesteps the conflict #1188 [imbcmdth@hotmail.com]

* Fixed missing id uniqueness in FormTag#radio_button #1207 [Jarkko]

* Fixed assert_redirected_to to work with :only_path => false #1204 [Alisdair McDiarmid]

* Fixed render_partial_collection to output an empty string instead of nil when handed an empty array #1202 [Ryan Carver]

* Improved the speed of regular expression expirations for caching by a factor of 10 #1221 [Jamis Buck]

* Removed dumping of template assigns on the rescue page as it would very easily include a ton of data making page loads take seconds (and the information was rarely helpful) #1222

* Added BenchmarkHelper that can measure the execution time of a block in a template and reports the result to the log. Example:
  
    <% benchmark "Notes section" do %>
      <%= expensive_notes_operation %>
    <% end %>
  
   Will add something like "Notes section (0.345234)" to the log.

* Added ActionController::Caching::Sweeper as an improved an easier to use sweeper. The new sweepers work on a single-step approach instead of two-steps like the old ones. Before

    def after_save(record)
      @list = record.is_a?(List) ? record : record.list
    end
    
    def filter(controller)
      controller.expire_page(:controller => "lists", :action => %w( show public feed ), :id => @list.id)
      controller.expire_action(:controller => "lists", :action => "all")
      @list.shares.each { |share| controller.expire_page(:controller => "lists", :action => "show", :id => share.url_key) }
    end

  ..after:

    def after_save(record)
      list = record.is_a?(List) ? record : record.list
      expire_page(:controller => "lists", :action => %w( show public feed ), :id => list.id)
      expire_action(:controller => "lists", :action => "all")
      list.shares.each { |share| expire_page(:controller => "lists", :action => "show", :id => share.url_key) }
    end

  The new sweepers can also observe on the actions themselves by implementing methods according to (before|after)_$controller_$action. Example of a callback that'll be called after PagesController#update_title has been performed:
  
      def after_pages_update_title
        expire_fragment(%r{pages/#{controller.assigns["page"].id}/.*})
      end

  Note that missing_method is delegated to the controller instance, which is assigned in a before filter. This means that you can call expire_fragment instead of @controller.expire_fragment.

* Added that Fragments#expire_fragment now accepts as a regular expression as the name thereby deprecating expire_matched_fragments

* Fixed that fragments shouldn't use the current host and the path as part of the key like pages does

* Added conditions to around_filters just like before_filter and after_filter


*1.8.1* (20th April, 2005)

* Added xml_http_request/xhr method for simulating XMLHttpRequest in functional tests #1151 [Sam Stephenson]. Example:

    xhr :post, :index

* Fixed that Ajax.Base.options.asynchronous wasn't being respected in Ajax.Request (thanks Jon Casey)

* Fixed that :get, :post, and the others should take a flash array as the third argument just like process #1144 [rails@cogentdude.com]

* Fixed a problem with Flash.now

* Fixed stringification on all assigned hashes. The sacrifice is that assigns[:person] won't work in testing. Instead assigns["person"] or assigns(:person) must be used. In other words, the keys of assigns stay strings but we've added a method-based accessor to appease the need for symbols.

* Fixed that rendering a template would require a connection to the database #1146


*1.8.0* (19th April, 2005)

* Added assert_tag and assert_no_tag as a much improved alternative to the deprecated assert_template_xpath_match #1126 [Jamis Buck]

* Deprecated the majority of all the testing assertions and replaced them with a much smaller core and access to all the collections the old assertions relied on. That way the regular test/unit assertions can be used against these. Added documentation about how to use it all.

* Added a wide range of new Javascript effects:
    * Effect.Puff zooms the element out and makes it smoothly transparent at the same time, giving a "puff" illusion #996 [thomas@fesch.at]
      After the animation is completed, the display property will be set to none. 
      This effect will work on relative and absolute positioned elements.
      
    * Effect.Appear as the opposite of Effect.Fade #990 [thomas@fesch.at]
      You should return elements with style="display:none;" or a like class for this to work best and have no chance of flicker.
      
    * Effect.Squish for scaling down an element and making it disappear at the end #972 [thomas@fesch.at]
    
    * Effect.Scale for smoothly scaling images or text up and down #972 [thomas@fesch.at]
    
    * Effect.Fade which smoothly turns opacity from 100 to 0 and then hides the element #960 [thomas@fesch.at]

* Added Request#xml_http_request? (and an alias xhr?) to that'll return true when the request came from one of the Javascript helper methods (Ajax). This can be used to give one behavior for modern browsers supporting Ajax, another to old browsers #1127 [Sam Stephenson]

* Changed render_partial to take local assigns as the second parameter instead of an explicit object and then the assigns. So the API changes from:

    <%= render_partial "account", person, "rules" => regulations.rules %>
    
  ...to:
  
    <%= render_partial "account", :account => person, :rules => regulations.rules %>
  
  The old API will still work, though, and render_partial "account" will still assume :account => @account.

* Added support for web servers that use PATH_INFO instead of REQUEST_URI like IIS #1014 [BradG/Nicholas Seckar]

* Added graceful handling of PUT, DELETE, and OPTIONS requests for a complete coverage of REST functionality #1136 [joshknowles@gmail.com]

* Fixed that you can now pass an alternative :href option to link_to_function/remote in order to point to somewhere other than # if the javascript fails or is turned off. You can do the same with form_remote_tag by passing in :action. #1113 [Sam Stephenson]

* Fixed DateHelper to return values on the option tags such that they'll work properly in IE with form_remote_tag #1024 [Scott Raymond]

* Fixed FormTagHelper#check_box to respect checked #1049 [DelynnB]

* Added that render_partial called from a controller will use the action name as default #828 [Dan Peterson]

* Added Element.toggle, Element.show, and Element.hide to the prototype javascript library. Toggle.display has been deprecated, but will still work #992 [Lucas Carlson]

* Added that deleting a cookie should not just set it to an empty string but also instantly expire it #1118 [todd@robotcoop.com]

* Added AssetTagHelper#image_path, AssetTagHelper#javascript_path, and AssetTagHelper#stylesheet_path #1110 [Larry Halff]

* Fixed url_for(nil) in functional tests #1116 [Alisdair McDiarmid]

* Fixed error handling of broken layouts #1115 [Michael Schubert]

* Added submit_to_remote that allows you to trigger an Ajax form submition at the click of the submission button, which allows for multiple targets in a single form through the use of multiple submit buttons #930 [yrashk@gmail.com]

* Fixed pagination to work with joins #1034 [scott@sigkill.org]

* Fixed that *rest parameter in map.connect couldn't accept an empty list #1037 [Dee.Zsombor@gmail.com]

* Added :confirm option to link_to_remote just like link_to has #1082 [yrashk@fp.org.ua]

* Added minute_step as an option to select_minute (and the helpers that use it) to jump in larger increments than just 1 minute. At 15, it would return 0, 15, 30, 45 options #1085 [ordwaye@evergreen.edu]

* Fixed that an exception would be thrown when an empty form was submitted #1090 [jan@ulbrich-boerwang.de]

* Moved TextHelper#human_size to NumberHelper#number_to_human_size, but kept an deprecated alias to the old method name

* Fixed that the content-type for some browsers could include an additional \r which made wonky things happen #1067 [Thomas Fuchs]

* Fixed that radio buttons shouldn't have a default size attribute #1074 [hendrik@mans.de]

* Added ActionView::Helpers::InstanceTag::DEFAULT_RADIO_OPTIONS that contains a hash of default options for radio buttons #1074 [hendrik@mans.de]

* Fixed that in some circumstances controllers outside of modules may have hidden ones inside modules. For example, admin/content might have been hidden by /content. #1075 [Nicholas Seckar]

* Added JavascriptHelper#periodically_call_remote in order to create areas of a page that update automatically at a set interval #945 [Jon Tirsen]

* Fixed Cache#expire_matched_fragments that couldn't recognize the difference between string and url_for options #1030 [skaes@web.de]

* Added simulation of @request.request_uri in functional tests #1038 [Jamis Buck]

* Fixed autolinking to work better in more cases #1013 [Jamis Buck]

* Added the possible of using symbols in form helpers that relate to instance variables like text_field :account, :name in addition to text_field "account", "name"'

* Fixed javascript_include_tag to output type instead of language and conform to XHTML #1018 [Rick Olson]

* Added NumberHelper for common string representations like phone number, currency, and percentage #1015 [DeLynn]

* Added pagination for scaffolding (10 items per page) #964 [mortonda@dgrmm.net]

* Added assert_no_cookie and fixed assert_cookie_equal to deal with non-existing cookies #979 [Jeremy Kemper]

* Fixed :overwrite_param so it doesn't delete but reject elements from @request.parameters #982 [raphinou@yahoo.com]

* Added :method option to verify for ensuring that either GET, POST, etc is allowed #984 [Jamis Buck]

* Added options to set cc, bcc, subject, and body for UrlHelper#mail_to #966 [DeLynn]

* Fixed include_blank for select_hour/minute/second #527 [edward@debian.org]

* Improved the message display on the exception handler pages #963 [Johan Sorensen]

* Fixed that on very rare occasions, webrick would raise a NoMethodError: private method 'split' called for nil #1001 [Flurin Egger]

* Fixed problem with page caching #958 [Rick Olson]


*1.7.0* (27th March, 2005)

* Added ActionController::Base.page_cache_extension for setting the page cache file extension (the default is .html) #903 [Andreas]

* Fixed "bad environment variable value" exception caused by Safari, Apache, and Ajax calls #918

* Fixed that pagination_helper would ignore :params #947 [Sebastian Kanthak]

* Added :owerwrite_params back to url_for and friends -- it was AWL since the introduction of Routes #921 [raphinou]

* Added :position option to link_to_remote/form_remote_tag that can be either :before, :top, :bottom, or :after and specifies where the return from the method should be inserted #952 [Matthew McCray/Sam Stephenson]

* Added Effect.Highlight to prototype.js to do Yellow Fade Technique (of 37signals' fame) on any container #952 [Sam Stephenson/courtenay]

* Added include_seconds option as the third parameter to distance_of_time_in_words which will render "less than a minute" in higher resolution ("less than 10 seconds" etc) #944 [thomas@fesch.at]

* Added fourth option to process in test cases to specify the content of the flash #949 [Jamis Buck]

* Added Verifications that allows you to specify preconditions to actions in form of statements like <tt>verify :only => :update_post, :params => "admin_privileges", :redirect_to => { :action => "settings" }</tt>, which ensure that the update_post action is only called if admin_privileges is available as a parameter -- otherwise the user is redirected to settings. #897 [Jamis Buck]

* Fixed Form.Serialize for the JavascriptHelper to also seriliaze password fields #934 [dweitzman@gmail.com]

* Added JavascriptHelper#escape_javascript as a public method (was private) and made it escape both single and double quotes and new lines #940 [mortonda@dgrmm.net]

* Added trailing_slash option to url_for, so you can generate urls ending in a slash. Note that is currently not recommended unless you need it for special reasons since it breaks caching #937 [stian@grytoyr.net]

* Added expire_matched_fragments(regular_expression) to clear out a lot of fragment caches at once #927 [technoweenie@gmail.com]

* Fixed the problems with : and ? in file names for fragment caches on Windows #927 [technoweenie@gmail.com]

* Added TextHelper#human_size for formatting file sizes, like human_size(1234567) => 1.2 MB #943 [thomas@fesch.at]

* Fixed link_to :confirm #936 [Nicholas Seckar]

* Improved error reporting especially around never shallowing exceptions. Debugging helpers should be much easier now #980 [Nicholas Seckar]

* Fixed Toggle.display in prototype.js #902 [Lucas Carlson]


*1.6.0* (22th March, 2005)

* Added a JavascriptHelper and accompanying prototype.js library that opens the world of Ajax to Action Pack with a large array of options for dynamically interacting with an application without reloading the page #884 [Sam Stephenson/David]

* Added pagination support through both a controller and helper add-on #817 [Sam Stephenson]

* Fixed routing and helpers to make Rails work on non-vhost setups #826 [Nicholas Seckar/Tobias Luetke]

* Added a much improved Flash module that allows for finer-grained control on expiration and allows you to flash the current action #839 [Caio Chassot]. Example of flash.now:

    class SomethingController < ApplicationController
      def save
        ...
        if @something.save
          # will redirect, use flash
          flash[:message] = 'Save successful'
          redirect_to :action => 'list'
        else
          # no redirect, message is for current action, use flash.now
          flash.now[:message] = 'Save failed, review'
          render_action 'edit'
        end
      end    
    end

* Added to_param call for parameters when composing an url using url_for from something else than strings #812 [Sam Stephenson]. Example:

    class Page
      def initialize(number)
        @number = number
      end
      # ...
      def to_param
        @number.to_s
      end
    end

  You can now use instances of Page with url_for:

    class BarController < ApplicationController
      def baz
        page = Page.new(4)
        url = url_for :page => page # => "http://foo/bar/baz?page=4"
      end
    end

* Fixed form helpers to query Model#id_before_type_cast instead of Model#id as a temporary workaround for Ruby 1.8.2 warnings #818 [DeLynn B]

* Fixed TextHelper#markdown to use blank? instead of empty? so it can deal with nil strings passed #814 [Johan Sörensen]

* Added TextHelper#simple_format as a non-dependency text presentation helper #814 [Johan Sörensen]

* Added that the html options disabled, readonly, and multiple can all be treated as booleans. So specifying <tt>disabled => :true</tt> will give <tt>disabled="disabled"</tt>. #809 [mindel]

* Added path collection syntax for Routes that will gobble up the rest of the url and pass it on to the controller #830 [rayners]. Example:

    map.connect 'categories/*path_info', :controller => 'categories', :action => 'show'

  A request for /categories/top-level-cat, would give @params[:path_info] with "top-level-cat".
  A request for /categories/top-level-cat/level-1-cat, would give @params[:path_info] with "top-level-cat/level-1-cat" and so forth.
  
  The @params[:path_info] return is really an array, but where to_s has been overwritten to do join("/").

* Fixed options_for_select on selected line issue #624 [Florian Weber]

* Added CaptureHelper with CaptureHelper#capture and CaptureHelper#content_for. See documentation in helper #837 [Tobias Luetke]

* Fixed :anchor use in url_for #821 [Nicholas Seckar]

* Removed the reliance on PATH_INFO as it was causing problems for caching and inhibited the new non-vhost support #822 [Nicholas Seckar]

* Added assigns shortcut for @response.template.assigns to controller test cases [Jeremy Kemper]. Example:

  Before:

    def test_list
      assert_equal 5, @response.template.assigns['recipes'].size
      assert_equal 8, @response.template.assigns['categories'].size
    end

  After:

    def test_list
      assert_equal 5, assigns(:recipes).size
      assert_equal 8, assigns(:categories).size
    end

* Added TagHelper#image_tag and deprecated UrlHelper#link_image_to (recommended approach is to combine image_tag and link_to instead)

* Fixed textilize to be resilient to getting nil parsed (by using Object#blank? instead of String#empty?)

* Fixed that the :multipart option in FormTagHelper#form_tag would be ignored [Yonatan Feldman]


*1.5.1* (7th March, 2005)

* Fixed that the routes.rb file wouldn't be found on symlinked setups due to File.expand_path #793 [piotr@t-p-l.com]

* Changed ActiveRecordStore to use Marshal instead of YAML as the latter proved troublesome in persisting circular dependencies. Updating existing applications MUST clear their existing session table from data to start using this updated store #739 [Jamis Buck]

* Added shortcut :id assignment to render_component and friends (before you had to go through :params) #784 [Lucas Carlson]

* Fixed that map.connect should convert arguments to strings #780 [Nicholas Seckar]

* Added UrlHelper#link_to_if/link_to_unless to enable other conditions that just link_to_unless_current #757 [mindel]

* Fixed that single quote was not escaped in a UrlHelper#link_to javascript confirm #549 [Scott Barron]

* Removed the default border on link_image_to (it broke xhtml strict) -- can be specified with :border => 0 #517 [?/caleb]

* Fixed that form helpers would treat string and symbol keys differently in html_options (and possibly create duplicate entries) #112 [Jeremy Kemper]

* Fixed that broken pipe errors (clients disconnecting in mid-request) could bring down a fcgi process

* Added the original exception message to session recall errors (so you can see which class wasnt required)

* Fixed that RAILS_ROOT might not be defined when AP was loaded, so do a late initialization of the ROUTE_FILE #761 [Scott Barron]

* Fix request.path_info and clear up LoadingModule behavior #754 [Nicholas Seckar]

* Fixed caching to be aware of extensions (so you can cache files like api.wsdl or logo.png) #734 [Nicholas Seckar]

* Fixed that Routes would raise NameErrors if a controller component contains characters that are not valid constant names #733 [Nicholas Seckar]

* Added PATH_INFO access from the request that allows urls like the following to be interpreted by rails: http://www.example.com/dispatcher.cgi/controller/action -- that makes it possible to use rails as a CGI under lighttpd and would also allow (for example) Rublog to be ported to rails without breaking existing links to Rublog-powered blogs. #728 [Jamis Buck]

* Fixed that caching the root would result in .html not index.html #731, #734 [alisdair/Nicholas Seckar]


*1.5.0* (24th February, 2005)

* Added Routing as a replacement for mod_rewrite pretty urls [Nicholas Seckar]. Read more in ActionController::Base.url_for and on http://manuals.rubyonrails.com/read/book/9

* Added components that allows you to call other actions for their rendered response while execution another action. You can either delegate the entire response rendering or you can mix a partial response in with your other content. Read more on http://manuals.rubyonrails.com/read/book/14

* Fixed that proxy IPs do not follow all RFC1918 nets #251 [caleb@aei-tech.com]

* Added Base#render_to_string to parse a template and get the result back as a string #479

* Fixed that send_file/data can work even if render* has been called before in action processing to render the content of a file to be send for example #601

* Added FormOptionsHelper#time_zone_select and FormOptionsHelper#time_zone_options_for_select to work with the new value object TimeZone in Active Support #688 [Jamis Buck]

* Added FormHelper#file_field and FormTagHelper#file_field_tag for creating file upload fields

* Added :order option for date_select that allows control over the order in which the date dropdowns is used and which of them should be used #619 [Tim Bates]. Examples:

    date_select("post", "written_on", :order => [:day, :month, :year])
    date_select("user", "birthday",   :order => [:month, :day])

* Added ActionView::Base.register_template_handler for easy integration of an alternative template language to ERb and Builder. See test/controller/custom_handler_test.rb for a usage example #656 [Jamis Buck]

* Added AssetTagHelper that provides methods for linking a HTML page together with other assets, such as javascripts, stylesheets, and feeds.

* Added FormTagHelper that provides a number of methods for creating form tags that doesn't rely on conventions with an object assigned to the template like FormHelper does. With the FormTagHelper, you provide the names and values yourself.

* Added Afghanistan, Iran, and Iraq to the countries list used by FormOptions#country_select and FormOptions#country_options_for_select

* Renamed link_to_image to link_image_to (since thats what it actually does) -- kept alias for the old method name

* Fixed textilize for RedCloth3 to keep doing hardbreaks

* Fixed that assert_template_xpath_matches did not indicate when a path was not found #658 [Eric Hodel]

* Added TextHelper#auto_link to turn email addresses and urls into ahrefs

* Fixed that on validation errors, scaffold couldn't find template #654 [mindel]

* Added Base#hide_action(*names) to hide public methods from a controller that would otherwise have been callable through the URL. For the majority of cases, its preferred just to make the methods you don't want to expose protected or private (so they'll automatically be hidden) -- but if you must have a public method, this is a way to make it uncallable. Base#hidden_actions retrieve the list of all hidden actions for the controller #644 [Nicholas Seckar]

* Fixed that a bunch of methods from ActionController::Base was accessible as actions (callable through a URL) when they shouldn't have been #644 [Nicholas Seckar]

* Added UrlHelper#current_page?(options) method to check if the url_for options passed corresponds to the current page

* Fixed https handling on other ports than 443 [Alan Gano]

* Added follow_redirect method for functional tests that'll get-request the redirect that was made. Example:

    def test_create_post
      post :create, "post" => { "title" => "Exciting!" }
      assert_redirected_to :action => "show"
      
      follow_redirect
      assert_rendered_file "post/show"
    end
  
  Limitation: Only works for redirects to other actions within the same controller.

* Fixed double requiring of models with the same name as the controller

* Fixed that query params could be forced to nil on a POST due to the raw post fix #562 [moriq@moriq.com]

* Fixed that cookies shouldn't be frozen in TestRequest #571 [Eric Hodel]


*1.4.0* (January 25th, 2005)

* Fixed problems with ActiveRecordStore under the development environment in Rails

* Fixed the ordering of attributes in the xml-decleration of Builder #540 [woeye]

* Added @request.raw_post as a convenience access to @request.env['RAW_POST_DATA'] #534 [Tobias Luetke]

* Added support for automatic id-based indexing for lists of items #532 [dblack]. Example:

    <% @students.each do |@student| %>
      <%= text_field "student[]", "first_name", :size => "20" %>
      <%= text_field "student[]", "last_name" %>
      <%= text_field "student[]", "grade", :size => "5" %>
    <% end %>
  
  ...would produce, for say David Black with id 123 and a grace of C+:
  
    <input id="student_123_first_name" name="student[123][first_name]" size="20"     size="30" type="text" value="David" />
    <input id="student_123_last_name" name="student[123][last_name]" size="30"  type="text" value="Black" />
    <input id="student_123_grade" name="student[123][grade]" size="5" type="text"  value="C+" />

* Added :application_prefix to url_for and friends that makes it easier to setup Rails in non-vhost environments #516 [Jamis Buck]

* Added :encode option to mail_to that'll allow you to masquarede the email address behind javascript or hex encoding #494 [Lucas Carlson]

* Fixed that the content-header was being set to application/octet_stream instead of application/octet-stream on send_date/file [Alexey]

* Removed the need for passing the binding when using CacheHelper#cache

* Added TestResponse#binary_content that'll return as a string the data sent through send_data/send_file for testing #500 [Alexey]

* Added @request.env['RAW_POST_DATA'] for people who need access to the data before Ruby's CGI has parsed it #505 [Jeremy Kemper]

* Fixed that a default fragment store wan't being set to MemoryStore as intended.

* Fixed that all redirect and render calls now return true, so you can use the pattern of "do and return". Example:

    def show
      redirect_to(:action => "login") and return unless @person.authenticated?
      render_text "I won't happen unless the person is authenticated"
    end

* Added that renders and redirects called in before_filters will have the same effect as returning false: stopping the chain. Example:

    class WeblogController
      before_filter { |c| c.send(:redirect_to_url("http://www.farfaraway.com")}) }
      
      def hello
        render_text "I will never be called"
      end
    end


* Added that only one render or redirect can happen per action. The first call wins and subsequent calls are ignored. Example:

    def do_something
      redirect_to :action => "elsewhere"
      render_action "overthere"
    end
  
  Only the redirect happens. The rendering call is simply ignored.


*1.3.1* (January 18th, 2005)

* Fixed a bug where cookies wouldn't be set if a symbol was used instead of a string as the key

* Added assert_cookie_equal to assert the contents of a named cookie

* Fixed bug in page caching that prevented it from working at all 


*1.3.0* (January 17th, 2005)

* Added an extensive caching module that offers three levels of granularity (page, action, fragment) and a variety of stores. 
  Read more in ActionController::Caching.

* Added the option of passing a block to ActiveRecordHelper#form in order to add more to the auto-generated form #469 [dom@sisna.com]

    form("entry", :action => "sign") do |form|
      form << content_tag("b", "Department")
      form << collection_select("department", "id", @departments, "id", "name")
    end

* Added arrays as a value option for params in url_for and friends #467 [Eric Anderson]. Example:

    url_for(:controller => 'user', :action => 'delete', :params => { 'username' =>  %( paul john steve ) } )
    # => /user/delete?username[]=paul&username[]=john&username[]=steve

* Fixed that controller tests can now assert on the use of cookies #466 [Alexey]

* Fixed that send_file would "remember" all the files sent by adding to the headers again and again #458 [Jeremy Kemper]

* Fixed url rewriter confusion when the controller or action name was a substring of the controller_prefix or action_prefix

* Added conditional layouts like <tt>layout "weblog_standard", :except => :rss</tt> #452 [Marcel Molina]

* Fixed that MemCacheStore wasn't included by default and added default MemCache object pointing to localhost #447 [Lucas Carlson]

* Added fourth argument to render_collection_of_partials that allows you to specify local_assigns -- just like render_partial #432 [zenspider]

* Fixed that host would choke when cgi.host returned nil #432 [Tobias Luetke]

* Added that form helpers now take an index option #448 [Tim Bates]

  Example:
    text_field "person", "name", "index" => 3

  Becomes:
    <input type="text" name="person[3][name]" id="person_3_name" value="<%= @person.name %>" />

* Fixed three issues with retrying breakpoints #417 [Florian Gross]

  1. Don't screw up pages that use multiple values for the same parameter (?foo=bar&foo=qux was converted to ?foo=barqux) 
  2. Don't screw up all forms when you click the "Retry with Breakpoint" link multiple times instead of reloading 
     (This caused the parameters to be added multiple times for GET forms leading to trouble.) 
  3. Don't add ?BP-RETRY=1 multiple times

* Added that all renders and redirects now return false, so they can be used as the last line in before_filters to stop execution.

  Before:
    def authenticate
      unless @session[:authenticated]
        redirect_to :controller => "account", :action => "login"
        return false
      end
    end
  
  After:
    def authenticate
      redirect_to(:controller => "account", :action => "login") unless @session[:authenticated]
    end

* Added conditional filters #431 [Marcel]. Example:

    class JournalController < ActionController::Base
      # only require authentication if the current action is edit or delete
      before_filter :authorize, :only_on => [ :edit, :delete ]
    
      private
        def authorize
          # redirect to login unless authenticated
        end
    end

* Added Base#render_nothing as a cleaner way of doing render_text "" when you're not interested in returning anything but an empty response.

* Added the possibility of passing nil to UrlHelper#link_to to use the link itself as the name


*1.2.0* (January 4th, 2005)

* Added MemCacheStore for storing session data in Danga's MemCache system [Bob Cottrell]
  Depends on: MemCached server (http://www.danga.com/memcached/), MemCache client (http://raa.ruby-lang.org/project/memcache/)

* Added thread-safety to the DRbStore #66, #389 [Ben Stiglitz]

* Added DateHelper#select_time and DateHelper#select_second #373 [Scott Baron]

* Added :host and :protocol options to url_for and friends to redirect to another host and protocol than the current.

* Added class declaration for the MissingFile exception #388 [Kent Sibilev]

* Added "short hypertext note with a hyperlink to the new URI(s)" to redirects to fulfill compliance with RFC 2616 (HTTP/1.1) section 10.3.3 #397 [Tim Bates]

* Added second boolean parameter to Base.redirect_to_url and Response#redirect to control whether the redirect is permanent or not (301 vs 302) #375 [Hodel]

* Fixed redirects when the controller and action is named the same. Still haven't fixed same controller, module, and action, though #201 [Josh]

* Fixed problems with running multiple functional tests in Rails under 1.8.2 by including hack for test/unit weirdness

* Fixed that @request.remote_ip didn't work in the test environment #369 [Bruno Mattarollo]


*1.1.0*

* Added search through session to clear out association caches at the end of each request. This makes it possible to place Active Record objects
  in the session without worrying about stale data in the associations (the main object is still subject to caching, naturally) #347 [Tobias Luetke]

* Added more informative exception when using helper :some_helper and the helper requires another file that fails, you'll get an
  error message tells you what file actually failed to load, rather than falling back on assuming it was the helper file itself #346 [dblack]

* Added use of *_before_type_cast for all input and text fields. This is helpful for getting "100,000" back on a integer-based 
  validation where the value would normally be "100".

* Added Request#port_string to get something like ":8080" back on 8080 and "" on 80 (or 443 with https).

* Added Request#domain (returns string) and Request#subdomains (returns array).

* Added POST support for the breakpoint retries, so form processing that raises an exception can be retried with the original request [Florian Gross]

* Fixed regression with Base#reset_session that wouldn't use the DEFAULT_SESSION_OPTIONS [adam@the-kramers.net]

* Fixed error rendering of rxml documents to not just swallow the exception and return 0 (still not guessing the right line, but hey)

* Fixed that textilize and markdown would instantiate their engines even on empty strings. This also fixes #333 [Ulysses]

* Fixed UrlHelper#link_to_unless so it doesn't care if the id is a string or fixnum [zenspider]


*1.0.1*

* Fixed a bug that would cause an ApplicationController to require itself three times and hence cause filters to be run three times [evl]


*1.0*

* Added that controllers will now attempt to require a model dependency with their name and in a singular attempt for their name.
  So both PostController and PostsController will automatically have the post.rb model required. If no model is found, no error is raised,
  as it is then expected that no match is available and the programmer will have included his own models.

* Fixed DateHelper#date_select so that you can pass include_blank as an option even if you don't use start_year and end_year #59 [what-a-day]

* Added that controllers will now search for a layout in $template_root/layouts/$controller_name.r(html|xml), so PostsController will look
  for layouts/posts.rhtml or layouts/posts.rxml and automatically configure this layout if found #307 [Marcel]

* Added FormHelper#radio_button to work with radio buttons like its already possible with check boxes [Michael Koziarski]

* Added TemplateError#backtrace that makes it much easier to debug template errors from unit and functional tests

* Added display of error messages with scaffolded form pages

* Added option to ERB templates to swallow newlines by using <% if something -%> instead of just <% if something %>. Example:

    class SomeController < ApplicationController
    <% if options[:scaffold] %>
      scaffold :<%= singular_name %>
    <% end %>
      helper :post
  
  ...produces this on post as singular_name:

    class SomeController < ApplicationController
    
      scaffold :post
    
      helper :post
  
  ...where as:

    class SomeController < ApplicationController
    <% if options[:scaffold] -%>
      scaffold :<%= singular_name %>
    <% end -%>
      helper :post
  
  ...produces:

    class SomeController < ApplicationController
      scaffold :post
      helper :post
  
  [This undocumented gem for ERb was uncovered by bitsweat]

* Fixed CgiRequest so that it'll now accept session options with Symbols as keys (as the documentation points out) [Suggested by Andreas]

* Added that render_partial will always by default include a counter with value 1 unless there is a counter passed in via the 
  local_assigns hash that overrides it. As a result, render_collection_of_partials can still be written in terms of render_partial
  and partials that make use of a counter can be called without problems from both render_collection_of_partials as well as
  render_partial #295 [marcel]

* Fixed CgiRequest#out to fall back to #write if $stdout doesn't have #syswrite [Jeremy Kemper]

* Fixed all helpers so that they use XHTML compliant double quotes for values instead of single quotes [htonl/bitsweat]

* Added link_to_image(src, options = {}, html_options = {}). Documentation:

    Creates a link tag to the image residing at the +src+ using an URL created by the set of +options+. See the valid options in
    link:classes/ActionController/Base.html#M000021. It's also possible to pass a string instead of an options hash to
    get a link tag that just points without consideration. The <tt>html_options</tt> works jointly for the image and ahref tag by
    letting the following special values enter the options on the image and the rest goes to the ahref:
    
    ::alt: If no alt text is given, the file name part of the +src+ is used (capitalized and without the extension)
    ::size: Supplied as "XxY", so "30x45" becomes width="30" and height="45"
    ::align: Sets the alignment, no special features
    
    The +src+ can be supplied as a... 
    * full path, like "/my_images/image.gif"
    * file name, like "rss.gif", that gets expanded to "/images/rss.gif"
    * file name without extension, like "logo", that gets expanded to "/images/logo.png"

* Fixed to_input_field_tag so it no longer explicitly uses InstanceTag.value if value was specified in the options hash [evl]

* Added the possibility of having validate be protected for assert_(in)valid_column #263 [Tobias Luetke]

* Added that ActiveRecordHelper#form now calls url_for on the :action option.

* Added all the HTTP methods as alternatives to the generic "process" for functional testing #276 [Tobias Luetke]. Examples:

    # Calls Controller#miletone with a GET request
    process :milestone
    
    # Calls Controller#miletone with a POST request that has parameters
    post :milestone, { "name" => "David" }
    
    # Calls Controller#milestone with a HEAD request that has both parameters and session data
    head :milestone, { "id" => 1 }, { "user_id" => 23 }

  This is especially useful for testing idiomatic REST web services.

* Added proper handling of HEAD requests, so that content isn't returned (Request#head? added as well) #277 [Eric Hodel]

* Added indifference to whether @headers["Content-Type"], @headers["Content-type"], or @headers["content-type"] is used.

* Added TestSession#session_id that returns an empty string to make it easier to functional test applications that doesn't use 
  cookie-based sessions #275 [jcf]

* Fixed that cached template loading would still check the file system to see if the file existed #258 [Andreas Schwarz]

* Added options to tailor header tag, div id, and div class on ActiveRecordHelper#error_messages_for [josh]

* Added graceful handling of non-alphanumeric names and misplaced brackets in input parameters [Jeremy Kemper]

* Added a new container for cookies that makes them more intuative to use. The old methods of cookie and @cookies have been deprecated.

  Examples for writing:

    cookies["user_name"] = "david" # => Will set a simple session cookie
    cookies["login"] = { "value" => "XJ-122", "expires" => Time.now + 360} # => Will set a cookie that expires in 1 hour
    
  Examples for reading:
  
    cookies["user_name"] # => "david"
    cookies.size         # => 2

  Read more in ActionController::Cookies

  NOTE: If you were using the old accessor (cookies instead of @cookies), this could potentially break your code -- if you expect a full cookie object!

* Added the opportunity to defined method_missing on a controller which will handle all requests for actions not otherwise defined #223 [timb]

* Fixed AbstractRequest#remote_ip for users going through proxies - Patch #228 [Eric Hodel]

* Added Request#ssl? which is shorthand for @request.protocol == "https://"

* Added the choice to call form_tag with no arguments (resulting in a form posting to current action) [Jeremy Kemper]

* Upgraded to Builder 1.2.1

* Added :module as an alias for :controller_prefix to url_for and friends, so you can do redirect_to(:module => "shop", :controller => "purchases")
  and go to /shop/purchases/

* Added support for controllers in modules through @params["module"].

* Added reloading for dependencies under cached environments like FastCGI and mod_ruby. This makes it possible to use those environments for development.
  This is turned on by default, but can be turned off with ActionController::Base.reload_dependencies = false in production environments.

  NOTE: This will only have an effect if you use the new model, service, and observer class methods to mark dependencies. All libraries loaded through
  require will be "forever" cached. You can, however, use ActionController::Base.load_or_require("library") to get this behavior outside of the new
  dependency style.

* Added that controllers will automatically require their own helper if possible. So instead of doing:

    class MsgController < ApplicationController
      helper :msg
    end
    
  ...you can just do:
  
    class MsgController < ApplicationController
    end

* Added dependencies_on(layer) to query the dependencies of a controller. Examples:
  
    MsgController.dependencies_on(:model)    # => [ :post, :comment, :attachment ]
    MsgController.dependencies_on(:service)  # => [ :notification_service ]
    MsgController.dependencies_on(:observer) # => [ :comment_observer ]

* Added a new dependency model with the class methods model, service, and observer. Example:

    class MsgController < ApplicationController
      model    :post, :comment, :attachment
      service  :notification_service
      observer :comment_observer
    end

  These new "keywords" remove the need for explicitly calling 'require' in most cases. The observer method even instantiates the
  observer as well as requiring it.

* Fixed that link_to would escape & in the url again after url_for already had done so


*0.9.5* (28)

* Added helper_method to designate that a given private or protected method you should available as a helper in the view. [Jeremy Kemper]

* Fixed assert_rendered_file so it actually verifies if that was the rendered file [htonl]

* Added the option for sharing partial spacer templates just like partials themselves [radsaq]

* Fixed that Russia was named twice in country_select [alexey]

* Fixed request_origin to use remote_ip instead of remote_addr [Jeremy Kemper]

* Fixed link_to breakage when nil was passed for html_options [alexey]

* Fixed redirect_to on a virtual server setup with apache with a port other than the default where it would forget the port number [seanohalpin]

* Fixed that auto-loading webrick on Windows would cause file uploads to fail [Jeremy Kemper]

* Fixed issues with sending files on WEBrick by setting the proper binmode [Jeremy Kemper]

* Added send_data as an alternative to send_file when the stream is not read off the filesystem but from a database or generated live [Jeremy Kemper]

* Added a new way to include helpers that doesn't require the include hack and can go without the explicit require. [Jeremy Kemper]

  Before:

    module WeblogHelper
      def self.included(controller) #:nodoc:
        controller.ancestors.include?(ActionController::Base) ? controller.add_template_helper(self) : super
      end
    end

    require 'weblog_helper'
    class WeblogController < ActionController::Base
      include WeblogHelper
    end
    
  After:

    module WeblogHelper
    end

    class WeblogController < ActionController::Base
      helper :weblog
    end

* Added a default content-type of "text/xml" to .rxml renders [Ryan Platte]

* Fixed that when /controller/index was requested by the browser, url_for would generates wrong URLs [Ryan Platte]

* Fixed a bug that would share cookies between users when using FastCGI and mod_ruby [The Robot Co-op]

* Added an optional third hash parameter to the process method in functional tests that takes the session data to be used [alexey]

* Added UrlHelper#mail_to to make it easier to create mailto: style ahrefs

* Added better error messages for layouts declared with the .rhtml extension (which they shouldn't) [geech]

* Added another case to DateHelper#distance_in_minutes to return "less than a minute" instead of "0 minutes" and "1 minute" instead of "1 minutes"

* Added a hidden field to checkboxes generated with FormHelper#check_box that will make sure that the unchecked value (usually 0)
  is sent even if the checkbox is not checked. This relieves the controller from doing custom checking if the checkbox wasn't
  checked. BEWARE: This might conflict with your run-on-the-mill work-around code. [Tobias Luetke]

* Fixed error_message_on to just use the first if more than one error had been added [marcel]

* Fixed that URL rewriting with /controller/ was working but /controller was not and that you couldn't use :id on index [geech]

* Fixed a bug with link_to where the :confirm option wouldn't be picked up if the link was a straight url instead of an option hash

* Changed scaffolding of forms to use <label> tags instead of <b> to please W3C [evl]

* Added DateHelper#distance_of_time_in_words_to_now(from_time) that works like distance_of_time_in_words, 
  but where <tt>to_time</tt> is fixed to <tt>Time.now</tt>.

* Added assert_flash_equal(expected, key, message), assert_session_equal(expected, key, message), 
  assert_assigned_equal(expected, key, message) to test the contents of flash, session, and template assigns.

* Improved the failure report on assert_success when the action triggered a redirection [alexey].

* Added "markdown" to accompany "textilize" as a TextHelper method for converting text to HTML using the Markdown syntax.
  BlueCloth must be installed in order for this method to become available.

* Made sure that an active session exists before we attempt to delete it [Samuel]

* Changed link_to with Javascript confirmation to use onclick instead of onClick for XHTML validity [Scott Barron]


*0.9.0 (43)*

* Added support for Builder-based templates for files with the .rxml extension. These new templates are an alternative to ERb that
  are especially useful for generating XML content, such as this RSS example from Basecamp:

    xml.rss("version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/") do
      xml.channel do
        xml.title(@feed_title)
        xml.link(@url)
        xml.description "Basecamp: Recent items"
        xml.language "en-us"
        xml.ttl "40"
    
        for item in @recent_items
          xml.item do
            xml.title(item_title(item))
            xml.description(item_description(item)) if item_description(item)
            xml.pubDate(item_pubDate(item))
            xml.guid(@person.firm.account.url + @recent_items.url(item))
            xml.link(@person.firm.account.url + @recent_items.url(item))
        
            xml.tag!("dc:creator", item.author_name) if item_has_creator?(item)
          end
        end
      end
    end

    ...which will generate something like:

    <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">
      <channel>
        <title>Web Site Redesign</title>
        <link>http://www.basecamphq.com/clients/travelcenter/1/</link>

  The "xml" local variable is automatically available in .rxml templates. You construct the template by calling a method with the name
  of the tag you want. Options for the tag can be specified as a hash parameter to that method.

  Builder-based templates can be mixed and matched with the regular ERb ones. The only thing that differentiates them is the extension.
  No new methods have been added to the public interface to handle them. 
  
  Action Pack ships with a version of Builder, but it will use the RubyGems version if you have one installed.
  
  Read more about Builder on: http://onestepback.org/index.cgi/Tech/Ruby/StayingSimple.rdoc
  
  [Builder is created by Jim Weirich]

* Added much improved support for functional testing [what-a-day].

    # Old style
    def test_failing_authenticate
      @request.request_uri = "/login/authenticate"
      @request.action = "authenticate"
      @request.request_parameters["user_name"] = "nop"
      @request.request_parameters["password"]  = ""
  
      response = LoginController.process_test(@request)
  
      assert_equal "The username and/or password you entered is invalid.", response.session["flash"]["alert"]
      assert_equal "http://37signals.basecamp.com/login/", response.headers["location"]
    end

    # New style
    def test_failing_authenticate
      process :authenticate, "user_name" => "nop", "password" => ""
      assert_flash_has 'alert'
      assert_redirected_to :action => "index"
    end

  See a full example on http://codepaste.org/view/paste/334

* Increased performance by up to 100% with a revised cookie class that fixes the performance problems with the 
  default one that ships with 1.8.1 and below. It replaces the inheritance on SimpleDelegator with DelegateClass(Array)
  following the suggestion from Matz on:
  http://groups.google.com/groups?th=e3a4e68ba042f842&seekm=c3sioe%241qvm%241%40news.cybercity.dk#link14

* Added caching for compiled ERb templates. On Basecamp, it gave between 8.5% and 71% increase in performance [Andreas Schwarz].

* Added implicit counter variable to render_collection_of_partials [Marcel]. From the docs:

    <%= render_collection_of_partials "ad", @advertisements %>
    
    This will render "advertiser/_ad.rhtml" and pass the local variable +ad+ to the template for display. An iteration counter
    will automatically be made available to the template with a name of the form +partial_name_counter+. In the case of the 
    example above, the template would be fed +ad_counter+.

* Fixed problems with two sessions being maintained on reset_session that would particularly screw up ActiveRecordStore.

* Fixed reset_session to start an entirely new session instead of merely deleting the old. So you can now safely access @session
  after calling reset_ression and expect it to work.

* Added @request.get?, @request.post?, @request.put?, @request.delete? as convenience query methods for @request.method [geech]

* Added @request.method that'll return a symbol representing the HTTP method, such as :get, :post, :put, :delete [geech]

* Changed @request.remote_ip and @request.host to work properly even when a proxy is in front of the application [geech]

* Added JavaScript confirm feature to link_to. Documentation:

    The html_options have a special feature for creating javascript confirm alerts where if you pass 
    :confirm => 'Are you sure?', the link will be guarded with a JS popup asking that question.
    If the user accepts, the link is processed, otherwise not.

* Added link_to_unless_current as a UrlHelper method [Sam Stephenson]. Documentation:

    Creates a link tag of the given +name+ using an URL created by the set of +options+, unless the current 
    controller, action, and id are the same as the link's, in which case only the name is returned (or the
    given block is yielded, if one exists). This is useful for creating link bars where you don't want to link 
    to the page currently being viewed.

* Fixed that UrlRewriter (the driver for url_for, link_to, etc) would blow up when the anchor was an integer [alexey]

* Added that layouts defined with no directory defaults to layouts. So layout "weblog/standard" will use
  weblog/standard (as always), but layout "standard" will use layouts/standard.

* Fixed that partials (or any template starting with an underscore) was publically viewable [Marten]

* Added HTML escaping to text_area helper.

* Added :overwrite_params to url_for and friends to keep the parameters as they were passed to the current action and only overwrite a subset.
  The regular :params will clear the slate so you need to manually add in existing parameters if you want to reuse them. [raphinou]

* Fixed scaffolding problem with composite named objects [Moo Jester]

* Added the possibility for shared partials. Example:

    <%= render_partial "advertisement/ad", ad %>
  
  This will render the partial "advertisement/_ad.rhtml" regardless of which controller this is being called from.
  
  [Jacob Fugal]

* Fixed crash when encountering forms that have empty-named fields [James Prudente]

* Added check_box form helper method now accepts true/false as well as 1/0 [what-a-day]

* Fixed the lacking creation of all directories with install.rb [Dave Steinberg]

* Fixed that date_select returns valid XHTML selected options [Andreas Schwarz]

* Fixed referencing an action with the same name as a controller in url_for [what-a-day]

* Fixed the destructive nature of Base#attributes= on the argument [Kevin Watt]

* Changed ActionControllerError to decent from StandardError instead of Exception. It can now be caught by a generic rescue.

* Added SessionRestoreError that is raised when a session being restored holds objects where there is no class available.

* Added block as option for inline filters. So what used to be written as:

    before_filter Proc { |controller| return false if controller.params["stop_action"] }

  ...can now be as:

    before_filter { |controller| return false if controller.params["stop_action"] }
  
  [Jeremy Kemper]

* Made the following methods public (was protected): url_for, controller_class_name, controller_name, action_name
  This makes it easier to write filters without cheating around the encapsulation with send.

* ActionController::Base#reset_session now sticks even if you access @session afterwards [Kent Sibilev]

* Improved the exception logging so the log file gets almost as much as in-browser debugging.

* Changed base class setup from AbstractTemplate/ERbTemplate to ActionView::Base. This change should be harmless unless you were
  accessing Action View directly in which case you now need to reference the Base class.\

* Added that render_collection_of_partials returns nil if the collection is empty. This makes showing a “no items” message easier. 
  For example: <%= render_collection_of_partials("message", @messages) || "No messages found." %> [Sam Stephenson]

* Added :month_before_year as an option to date_select to get the month select before the year. Especially useful for credit card forms.

* Added :add_month_numbers to select_month to get options like "3 - March".

* Removed Base.has_active_layout? as it couldn't answer the question without the instance. Use Base#active_layout instead.

* Removed redundant call to update on ActionController::Base#close_session [Andreas Schwarz]

* Fixed that DRb Store accidently started its own server (instead of just client) [Andreas]

* Fixed strip_links so it now works across multiple lines [Chad Fowler]

* Fixed the TemplateError exception to show the proper trace on to_s (useful for unit test debugging)

* Implemented class inheritable attributes without eval [Caio Chassot]

* Made TextHelper#concat accept binding as it would otherwise not work

* The FormOptionsHelper will now call to_s on the keys and values used to generate options


*0.8.5*

* Introduced passing of locally scoped variables between templates:

    You can pass local variables to sub templates by using a hash of with the variable 
    names as keys and the objects as values:
    
      <%= render "shared/header", { "headline" => "Welcome", "person" => person } %>
    
    These can now be accessed in shared/header with:
    
      Headline: <%= headline %>
      First name: <%= person.first_name %>
    
* Introduced the concept of partials as a certain type of sub templates:

    There's also a convenience method for rendering sub templates within the current 
    controller that depends on a single object (we call this kind of sub templates for 
    partials). It relies on the fact that partials should follow the naming convention
    of being prefixed with an underscore -- as to separate them from regular templates
    that could be rendered on their own. In the template for Advertiser#buy, we could have:
    
      <% for ad in @advertisements %>
        <%= render_partial "ad", ad %>
      <% end %>
    
    This would render "advertiser/_ad.rhtml" and pass the local variable +ad+ 
    for the template to display.
    
    == Rendering a collection of partials
    
    The example of partial use describes a familar pattern where a template needs
    to iterate over a array and render a sub template for each of the elements. 
    This pattern has been implemented as a single method that accepts an array and 
    renders a partial by the same name of as the elements contained within. So the 
    three-lined example in "Using partials" can be rewritten with a single line:
    
      <%= render_collection_of_partials "ad", @advertisements %>
    
    So this will render "advertiser/_ad.rhtml" and pass the local variable +ad+ for 
    the template to display.

* Improved send_file by allowing a wide range of options to be applied [Jeremy Kemper]:

    Sends the file by streaming it 4096 bytes at a time. This way the
    whole file doesn't need to be read into memory at once.  This makes
    it feasible to send even large files.
    
    Be careful to sanitize the path parameter if it coming from a web
    page.  send_file(@params['path'] allows a malicious user to
    download any file on your server.
    
    Options:
    * <tt>:filename</tt> - specifies the filename the browser will see.  
      Defaults to File.basename(path).
    * <tt>:type</tt> - specifies an HTTP content type.  
      Defaults to 'application/octet-stream'.
    * <tt>:disposition</tt> - specifies whether the file will be shown inline or downloaded.  
      Valid values are 'inline' and 'attachment' (default).
    * <tt>:buffer_size</tt> - specifies size (in bytes) of the buffer used to stream
      the file.  Defaults to 4096.
    
    The default Content-Type and Content-Disposition headers are
    set to download arbitrary binary files in as many browsers as
    possible.  IE versions 4, 5, 5.5, and 6 are all known to have
    a variety of quirks (especially when downloading over SSL).
    
    Simple download:
      send_file '/path/to.zip'
    
    Show a JPEG in browser:
      send_file '/path/to.jpeg', :type => 'image/jpeg', :disposition => 'inline'
    
    Read about the other Content-* HTTP headers if you'd like to
    provide the user with more information (such as Content-Description).
    http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.11
    
    Also be aware that the document may be cached by proxies and browsers.
    The Pragma and Cache-Control headers declare how the file may be cached
    by intermediaries.  They default to require clients to validate with
    the server before releasing cached responses.  See
    http://www.mnot.net/cache_docs/ for an overview of web caching and
    http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9
    for the Cache-Control header spec.

* Added pluralize method to the TextHelper that makes it easy to get strings like "1 message", "3 messages"

* Added proper escaping for the rescues [Andreas Schwarz]

* Added proper escaping for the option and collection tags [Andreas Schwarz]

* Fixed NaN errors on benchmarking [Jim Weirich]

* Fixed query string parsing for URLs that use the escaped versions of & or ; as part of a key or value

* Fixed bug with custom Content-Type headers being in addition to rather than instead of the default header.
  (This bug didn't matter with neither CGI or mod_ruby, but FCGI exploded on it) [With help from Ara T. Howard]


*0.8.0*

* Added select, collection_select, and country_select to make it easier for Active Records to set attributes through
  drop-down lists of options. Example:
  
    <%= select "person", "gender", %w( Male Female ) %>
    
  ...would give the following:
  
    <select name="person[gender]" id="person_gender"><option>Male</option><option>Female</option></select>

* Added an option for getting multiple values on a single form name into an array instead of having the last one overwrite.
  This is especially useful for groups of checkboxes, which can now be written as:
  
    <input type="checkbox" name="rights[]" value="CREATE" />
    <input type="checkbox" name="rights[]" value="UPDATE" />
    <input type="checkbox" name="rights[]" value="DELETE" />
  
  ...and retrieved in the controller action with:
  
    @params["rights"] # => [ "CREATE", "UPDATE", "DELETE" ]
  
  The old behavior (where the last one wins, "DELETE" in the example) is still available. Just don't add "[]" to the 
  end of the name. [Scott Baron]
  
* Added send_file which uses the new render_text block acceptance to make it feasible to send large files.
  The files is sent with a bunch of voodoo HTTP headers required to get arbitrary files to download as 
  expected in as many browsers as possible (eg, IE hacks). Example:
  
  def play_movie
    send_file "/movies/that_movie.avi"

* render_text now accepts a block for deferred rendering. Useful for streaming large files, displaying 
  a “please wait” message during a complex search, etc. Streaming example:
  
    render_text do |response|
      File.open(path, 'rb') do |file|
        while buf = file.read(1024)
          print buf 
        end 
      end
    end

* Added a new Tag Helper that can generate generic tags programmatically insted of through HTML. Example:
    
    tag("br", "clear" => "all") => <br clear="all" />
  
  ...that's usually not terribly interesting (unless you have a lot of options already in a hash), but it 
  gives way for more specific tags, like the new form tag:
  
    form_tag({ :controller => "weblog", :action => "update" }, { :multipart => "true", "style" => "width: 200px"}) =>
      <form action="/weblog/update" enctype="multipart/formdata" style="width: 200px">
    
  There's even a "pretty" version for people who don't like to open tags in code and close them in HTML:
  
    <%= start_form_tag :action => "update" %>
      # all the input fields
    <%= end_form_tag %>
  
  (end_form_tag just returns "</form>")

* The selected parameter in options_for_select may now also an array of values to be selected when 
  using a multiple select. Example:

    options_for_select([ "VISA", "Mastercard", "Discover" ], ["VISA", "Discover"]) =>
      <option selected>VISA</option>\n<option>Mastercard</option>\n<option selected>Discover</option>
      
  [Scott Baron]

* Changed the URL rewriter so controller_prefix and action_prefix can be used in isolation. You can now do:

    url_for(:controller_prefix => "clients")

  ...or:
  
    url_for(:action_prefix => "category/messages")

  Neither would have worked in isolation before (:controller_prefix required a :controller and :action_prefix required an :action)

* Started process of a cleaner separation between Action Controller and ERb-based Action Views by introducing an
  abstract base class for views. And Amita adapter could be fitted in more easily now.

* The date helper methods date_select and datetime_select now also use the field error wrapping 
  (div with class fieldWithErrors by default).

* The date helper methods date_select and datetime_select can now discard selects

* Added option on AbstractTemplate to specify a different field error wrapping. Example:

    ActionView::AbstractTemplate.field_error_proc = Proc.new do |html, instance|
      "<p>#{instance.method_name + instance.error_message}</p><div style='background-color: red'>#{html}</div>"
    end

  ...would give the following on a Post#title (text field) error:
  
    <p>Title can't be empty</p>
    <div style='background-color: red'>
      <input id="post_title" name="post[title]" size="30" type="text" value="Hello World" />
    </div>

* The UrlHelper methods url_for and link_to will now by default only return paths, not complete URIs.
  That should make it easier to fit a Rails application behind a proxy or load-balancer.
  You can overwrite this by passing :only_path => false as part of the options. [Suggested by U235]

* Fixed bug with having your own layout for use with scaffolding [Kevin Radloff]

* Fixed bug where redirect_to_path didn't append the port on non-standard ports [dhawkins]

* Scaffolding plays nicely with single-table inheritance (LoadErrors are caught) [Jeremy Kemper]

* Scaffolding plays nice with plural models like Category/categories [Jeremy Kemper]

* Fixed missing suffix appending in scaffolding [Kevin Radloff]


*0.7.9*

* The "form" method now present boolean fields from PostgreSQL as drop-down menu. [Scott]

* Scaffolding now automatically attempts to require the class that's being scaffolded.

* Scaffolding will use the current active layout, instead of its own, if one has been specified. Example:

    class WeblogController < ActionController::Base
      layout "layouts/weblog"
      scaffold :post
    end
  
  [Suggested by Scott]

* Changed url_for (and all the that drives, like redirect_to, link_to, link_for) so you can pass it a symbol instead of a hash.
  This symbol is a method reference which is then called to calculate the url. Example:
  
    class WeblogController < ActionController::Base
      def update
        # do some update
        redirect_to :dashboard_url
      end
      
      protected
        def dashboard_url
          if @project.active?
            url_for :controller => "project", :action => "dashboard"
          else
            url_for :controller => "account", :action => "dashboard"
          end
        end
    end
      
* Added default_url_options to specialize behavior for all url_for (and friends) calls:

    Overwrite to implement a number of default options that all url_for-based methods will use. 
    The default options should come in form of a hash, just like the one you would use for 
    url_for directly. Example:
    
      def default_url_options(options)
        { :controller_prefix => @project.active? ? "projects/" : "accounts/" }
      end
    
    As you can infer from the example, this is mostly useful for situations where you want to 
    centralize dynamic dissions about the urls as they stem from the business domain. Please note
    that any individual url_for call can always override the defaults set by this method.
    

* Changed url_for so that an "id" passed in the :params is not treated special. You need to use the dedicated :id to get 
  the special auto path-params treatment. Considering the url http://localhost:81/friends/list

    url_for(:action => "show", :params => { "id" => 5 })
      ...used to give http://localhost:81/friends/show/5
      ......now gives http://localhost:81/friends/show?id=5

    If you want the automated id behavior, do:

    url_for(:action => "show", :id => 5 )
      ....which gives http://localhost:81/friends/show/5


* Fixed problem with anchor being inserted before path parameters with url_for (and friends)


*0.7.8*

* Fixed session bug where you couldn't store any objects that didn't exist in the standard library 
  (such as Active Record objects).

* Added reset_session method for Action Controller objects to clear out all objects in the session.

* Fixed that exceptions raised during filters are now also caught by the default rescues

* Added new around_filter for doing before and after filtering with a single object [Florian Weber]:

    class WeblogController < ActionController::Base
      around_filter BenchmarkingFilter.new
      
      # Before this action is performed, BenchmarkingFilter#before(controller) is executed
      def index
      end
      # After this action has been performed, BenchmarkingFilter#after(controller) is executed
    end
    
    class BenchmarkingFilter
      def initialize
        @runtime
      end
      
      def before
        start_timer
      end
      
      def after
        stop_timer
        report_result
      end
    end

* Added the options for specifying a different name and id for the form helper methods than what is guessed [Florian Weber]:

    text_field "post", "title"
      ...just gives: <input id="post_title" name="post[title]" size="30" type="text" value="" />
      
    text_field "post", "title", "id" => "title_for_post", "name" => "first_post_title"
      ...can now give: <input id="title_for_post" name="first_post_title" size="30" type="text" value="" />

* Added DebugHelper with a single "debug" method for doing pretty dumps of objects in the view
  (now used in the default rescues to better present the contents of session and template variables)

* Added note to log about the templates rendered within layouts (before just the layout was shown)

* Fixed redirects on https setups [Andreas]

* Fixed scaffolding problem on the edit action when using :suffix => true [Scott]

* Fixed scaffolding problem where implementing list.rhtml wouldn't work for the index action

* URLs generated now uses &amp; instead of just & so pages using it can validate with W3C [Spotted by Andreas]


*0.7.7*

* Fixed bug in CGI extension that prevented multipart forms from working


*0.7.6*

* Included ERB::Util so all templates can easily escape HTML content with <%=h @person.content %>

* All requests are now considered local by default, so everyone will be exposed to detailed debugging screens on errors.
  When the application is ready to go public, set ActionController::Base.consider_all_requests_local to false, 
  and implement the protected method local_request? in the controller to determine when debugging screens should be shown.

* Fixed three bugs with the url_for/redirect_to/link_to handling. Considering the url http://localhost:81/friends/show/1

    url_for(:action => "list")
      ...used to give http://localhost:81/friends/list/1
      ......now gives http://localhost:81/friends/list
    
    url_for(:controller => "friends", :action => "destroy", :id => 5)
      ...used to give http://localhost:81/friends/destroy
      ......now gives http://localhost:81/friends/destroy/5

  Considering the url http://localhost:81/teachers/show/t

    url_for(:action => "list", :id => 5)
      ...used to give http://localhost:81/5eachers/list/t
      ......now gives http://localhost:81/teachers/list/5
