* 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]

* 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.

* 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 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 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 = {}, *parameters_for_method_reference). 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.append_features(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 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 Schwartz]

* Added proper escaping for the option and collection tags [Andreas Schwartz]

* 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"
  end
  
  [Jeremy Kemper]

* 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
  
  [Jeremy Kemper]

* 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
