*SVN*

* Ruby 1.9 compatibility.  #1689, #10466, #10468, #10554 [Cheah Chu Yeow, Pratik Naik, Jeremy Kemper, Dirkjan Bussink]

* TimeZone#to_s uses UTC rather than GMT.  #1689 [Cheah Chu Yeow]

* Refactor of Hash#symbolize_keys! to use Hash#replace.  Closes #10420 [ReinH]

* Fix HashWithIndifferentAccess#to_options! so it doesn't clear the options hash.  Closes #10419 [ReinH]


*2.0.1* (December 7th, 2007)

* Added Array#from and Array#to that behaves just from String#from and String#to [DHH]

* Fix that empty collections should be treated as empty arrays regardless of whitespace for Hash#from_xml #10255 [adamj]

* Time#time_with_datetime_fallback, Time#to_datetime, Date#to_datetime and String#to_datetime honor Ruby's default calendar reform setting. #10201 [Geoff Buesing]

* Change Time and DateTime #end_of_month to return last second of month instead of beginning of last day of month. Closes #10200 [Geoff Buesing]

* Speedup String#blank?  [Jeremy Kemper, Koz]

* Add documentation for Hash#diff. Closes #9306 [Tarmo Tänav]

* Add new superclass_delegating_accessors.  Similar to class inheritable attributes but with subtly different semantics. [Koz, Tarmo Tänav]

* Change JSON to encode %w(< > &) as 4 digit hex codes to be in compliance with the JSON spec.  Closes #9975 [Josh Peek, Cheah Chu Yeow, Tim Pope]

* Fix JSON encoding/decoding bugs dealing with /'s.  Closes #9990 [Rick, theamazingrando]

* Introduce a base class for all test cases used by rails applications. ActiveSupport::TestCase [Koz]

  The intention is to use this to reduce the amount of monkeypatching / overriding that 
  is done to test/unit's classes.

* Document Enumerable and Hash #to_json.  #9970 [Cheah Chu Yeow]

* Hash#to_xml handles symbol values.  #9954 [Assaf]

* Hash#symbolize_keys behaves well with integer keys.  #9890 [PotatoSalad]

* Multibyte: String#slice supports regexp argument.  #9646 [yob]

* object.duplicable? returns true if object.dup is safe. False for nil, true, false, symbols, and numbers; true otherwise.  #9333 [sur]

* Time, Date and DateTime #advance accept :weeks option.  #9866 [Geoff Buesing]

* Fix Time#years_ago and #years_since from leap days.  #9865 [Geoff Buesing]

* Time and DateTime#advance accept :hours, :minutes, and :seconds options.  #9825 [Geoff Buesing]

* Fix Date#years_ago and #years_since from leap days.  #9864 [Geoff Buesing]

* Refactor Time and Date#months_since and #months_ago to use #advance.  #9863 [Geoff Buesing]

* Rebundle Builder 2.1.2 but prefer a newer RubyGem if available.  [Jeremy Kemper]

* Add Range#overlaps?(range), Range#include?(range), and Range#step without a block. [brandon]

* Correct BufferedLogger#level? checks.  #9806 [wildchild, Johan Sorensen]

* String#to_xs uses Eric Wong's fast_xs extension, if available, for Builder speedup.  http://bogomips.org/fast_xs/  [Jeremy Kemper]

* Introduce BasicObject as Builder::BlankSlate for Ruby 1.9 forward compatibility.  [Jeremy Kemper]

* Unbundle Builder in favor of a gem dependency.  [Jeremy Kemper]

* Disambiguate Time, Date, and DateTime#to_json formatting.  #9750 [Geoff Buesing, Cheah Chu Yeow]

* Hash#to_json takes :only or :except options to specific or omit certain hash keys. Enumerable#to_json passes through its options to each element.  #9751 [Cheah Chu Yeow]

* BufferedLogger#auto_flushing = N flushes the log every N messages. Buffers with an array instead of string. Disabling auto_flushing still flushes when the buffer hits a maximum size, as a failsafe against memory-gobbling.  [Jeremy Kemper]

* Fixed Date#xmlschema for dates outside the range of what can be created with Time #9744 [Geoff Buesing]

* Fixed that La Paz was included in -25200 and -14400 offsets when it should only be in -14400 #9735 [bermi]

* Fixed JSON encoding to use quoted keys according to the JSON standard.  #8762 [choonkat, Cheah Chu Yeow]

* Alias Object#send to send! for Ruby 1.9 forward compatibility.  [Jeremy Kemper]

* Backport Object#instance_variable_defined? for Ruby < 1.8.6.  [Jeremy Kemper]

* BufferedLogger#add converts the message to a string.  #9702, #9724 [eigentone, DrMark, tomafro]

* Added ActiveSupport::BufferedLogger as a duck-typing alternative (albeit with no formatter) to the Ruby Logger, which provides a very nice speed bump (inspired by Ezra's buffered logger) [DHH]

* Object#instance_exec produces fewer garbage methods.  [Mauricio Fernandez]

* Decode json strings as Dates/Times if they're using a YAML-compatible format.  Closes #9614 [Rick]

* Fixed cache_page to use the request url instead of the routing options when picking a save path.  #8614 [Josh Peek]

* Object.subclasses_of includes anonymous subclasses.  [Jeremy Kemper]

* Fixed that pluralizing an empty string should return the same empty string, not "s".  #7720 [Josh Peek]

* Added call to inspect on non-string classes for the logger #8533 [codahale]

* Deprecation: remove deprecated :mday option from Time, Date, and DateTime#change.  [Jeremy Kemper]

* Fix JSON decoder with nested quotes and commas.  #9579 [zdennis]

* Hash#to_xml doesn't double-unescape.  #8806 [Ezran]

* Added Array#rand #9170 [Norbert Crombach]. Examples:

    [].rand       # => nil
    ['a'].rand    # => 'a'
    [1,2,3].rand  # => 1 or 2 or 3

* Deprecation: removed Reloadable.  [Jeremy Kemper]

* Make the utf-handler return the correct value for non-matching regular expressions. Closes #9049 [manfred]

* Add ljust, rjust and center to utf8-handler. Closes #9165 [manfred]

* Fix Time#advance bug when trying to advance a year from leap day.  Closes #8655 [gbuesing]

* Add support for []= on ActiveSupport::Multibyte::Chars. Closes #9142. [ewan, manfred]

* Added Array#extract_options! to encapsulate the pattern of getting an options hash out of a variable number of parameters.  #8759 [Norbert Crombach]

* Let alias_attribute work with attributes with initial capital letters (legacy columns etc).  Closes #8596 [mpalmer]

* Added Hash#except which is the inverse of Hash#slice -- return the hash except the keys that are specified [DHH]

* Added support for pluralization with a different starting letter than the singular version (cow/kine) #4929 [norri_b/hasmanyjosh]

* Demote Hash#to_xml to use XmlSimple#xml_in_string so it can't read files or stdin.  #8453 [candlerb, Jeremy Kemper]

* Backport clean_logger changes to support ruby 1.8.2 [mislav]

* Added proper handling of arrays #8537 [hasmanyjosh]

  Before:
    Hash.from_xml '<images></images>'
    # => {:images => nil}

    Hash.from_xml '<images><image>foo.jpg</image></images>'
    # => {:images => {:image => "foo.jpg"}}

    Hash.from_xml '<images><image>foo.jpg</image><image>bar.jpg</image></images>'
    # => {:images => {:image => ["foo.jpg", "bar.jpg"]}}

  After:
    Hash.from_xml '<images type="array"></images>'
    # => {:images => []}

    Hash.from_xml '<images type="array"><image>foo.jpg</image></images>'
    # => {:images => ["foo.jpg"]}

    Hash.from_xml '<images type="array"><image>foo.jpg</image><image>bar.jpg</image></images>'
    # => {:images => ["foo.jpg", "bar.jpg"]}

* Improve Time and Date test coverage.  #8646 [Josh Peek]

* Added assert_difference and assert_no_difference to test/unit assertions [Tobias Luetke]

* Removed breakpointer and Binding.of_caller in favor of relying on ruby-debug by Kent Sibilev since the breakpointer has been broken since Ruby 1.8.4 and will not be coming back [DHH]

* Added parsing of file type in Hash.xml_in so you can easily do file uploads with base64 from an API [DHH]

    <person>
      <name>David</name>
      <avatar type="file" name="me.jpg" content_type="image/jpg">R0lGODlhkACZAPUAAM5lcfjrtMQCG=\n</avatar>
    </person>
  
  ...becomes:
  
    attributes = { :person => { :name => "David", :avatar => #<StringIO> } }
    attributes[:person][:avatar].content_type      # => "image/jpg"
    attributes[:person][:avatar].original_filename # => "me.jpg"
    attributes[:person][:avatar].read # => binary data of the file
  
  Which is duck-type compatible with the files that you get when doing multipart uploads through HTML.

* Improved multibyte performance by relying less on exception raising #8159 [Blaine]

* Use XSD-compatible type names for Hash#to_xml and make the converters extendable #8047 [Tim Pope]

* Added yielding of builder in Hash#to_xml [DHH]

* Hash#with_indifferent_access now also converts hashes kept in arrays to indifferent access (makes it easier to treat HTML and XML parameters the same) [DHH]

* Hash#to_xml supports YAML attributes.  #7502 [jonathan]

* Refactor ActiveSupport::JSON to be less obtuse.  Add support for JSON decoding by way of Syck with ActiveSupport::JSON.decode(json_string).  Prevent hash keys that are JavaScript reserved words from being unquoted during encoding.  [Sam Stephenson]

* alias_method_chain preserves the original method's visibility.  #7854 [Jonathan Viney]

* Update Dependencies to ignore constants inherited from ancestors. Closes #6951. [Nicholas Seckar]

* Array#to_query preserves its ordering.  #7756 [Greg Spurrier]

* Out-of-range Time calculations transparently overflow to DateTime. Introduce Time#to_datetime.  #7706, #7715 [Geoff Buesing]

* DateTime calculations analogous to the Date and Time extensions.  #7693 [Geoff Buesing]

* Give DateTime correct .to_s implementations, lets it play nice with ActiveRecord quoting.  #7649 [Geoff Buesing]

* Add File.atomic_write,  allows you to write large files in an atomic manner, preventing users from seeing half written files.  [Koz]

* Allow users to provide custom formatters to Logger. [aeden]

* Hash#to_query CGI-escapes its keys.  [Jeremy Kemper]

* Optimize Class Inheritable Attributes so that unnecessary hashes are not created.  Closes #7472 [Bruce Perens]

    Date.new(2007, 1, 27).to_s(:db) # => '2007-01-27'

* Added :instance_writer option to #mattr_writer/accessor, #cattr_writer/accessor, and #class_inheritable_writer to skip the creation of the instance writer.  [Rick]

* Increase test coverage for subclasses_of. Closes #7335. [Roman2K, Nicholas Seckar]

* Remove unused code from Duration#inspect.  Closes #7180.  [Rich Collins]

* Added test coverage for Inflector.inflections.clear.  Closes #7179. [Rich Collins]

* ActiveSupport::Multibyte::Handlers::UTF8Handler should raise when a range and an integer are passed in (just like the native implementation).  Closes #7176 [Rich Collins]

* A couple extra tests for #classify.  Closes #7273. [Josh Susser]

* Better docs for Object extensions [zackchandler, Jamis Buck]

* Fix that Dates couldn't be subtracted from Dates after [5940].  [Sam Stephenson]

*1.4.1* (February 5th, 2007)

* Optimize Class Inheritable Attributes so that unnecessary hashes are not created.  Closes #7472 [Bruce Perens]

* Added :instance_writer option to #mattr_writer/accessor, #cattr_writer/accessor, and #class_inheritable_writer to skip the creation of the instance writer.  [Rick]

* Full test coverage for Inflector.  #7228 [Dan Kubb]


*1.4.0* (January 16th, 2007)

* Document Inflector.ordinalize and merge docs from String inflections.  #7023 [smeade]

* Unbundle flexmock.  [Jeremy Kemper]

* Fix Dependencies.autoloaded? to ignore anonymous modules. Closes #6561. [Nicholas Seckar]

* Update load once paths to prevent nested once constants from being detected and claimed by an external non-once load. [Nicholas Seckar]

* Deprecation: silence warnings when reporting test errors.  [Jeremy Kemper]

* Hash#slice(*keys) returns a new hash with only the given keys. #slice! replaces the hash with only the given keys. Works with HashWithIndifferentAccess also.  [Jeremy Kemper]

* HashWithIndifferentAccess#to_hash converts to a Hash with String keys and the same default value.  [Jeremy Kemper]

* Fix remove_constant to correctly handle constant names of the form "::A::...". References #6720. [Nicholas Seckar]

* Fixed Array#to_xml when it contains a series of hashes (each piece would get its own XML declaration) #6610 [thkarcher/cyu]

* Added Time#to_s(:time) which will just return H:M, like 17:44 [DHH]

* Add Module#attr_accessor_with_default to initialize value of attribute before setting it. Closes #6538. [Stuart Halloway, Marcel Molina Jr.]

* Hash#to_xml handles keys with the same name as Kernel methods.  #6613 [Catfish]

* Added Time#end_of_day to get 23:59:59 of that day [DHH]

* Update dependencies to delete partially loaded constants. [Nicholas Seckar]

* Fix unicode JSON regexp for Onigurama compatibility.  #6494 [whitley]

* Update dependencies to allow constants to be defined alongside their siblings. A common case for this is AR model classes with STI; user.rb might define User, Administrator and Guest for example. [Nicholas Seckar]

* next_week respects DST changes.  #6483, #5617, #2353, #2509, #4551 [marclove, rabiedenharn, rails@roetzel.de, jsolson@damogran.org, drbrain@segment7.net]

* Expose methods added to Enumerable in the documentation, such as group_by. Closes #6170. [sergeykojin@gmail.com, Marcel Molina Jr.]

* Fix issue with #class_inheritable_accessor saving updates to the parent class when initialized with an Array or Hash [mojombo]

* Hash#to_xml supports Bignum and BigDecimal.  #6313 [edibiase]

* Don't undefine #class in OptionMerger [Rick]

* Hash.create_from_xml has been renamed to Hash.from_xml, alias will exist until Rails 2.0 [DHH]

* alias_method_chain works with accessor= methods also.  #6153 [Caio Chassot]

* Fix loadable_constants_for_path to handle load paths that do not end with a slash. [Nicholas Seckar]

* Fix logic error in determining what was loaded by a given file. Closes #6039. [Nicholas Seckar]

* Equate Kernel.const_missing with Object.const_missing. Fixes #5988. [Nicholas Seckar]

* Add ApplicationController special case to Dependencies. [Nicholas Seckar]

* Don't pad remaining places with in_groups_of if specified padding value is false. [Marcel Molina Jr.]

* Fix cases where empty xml nodes weren't being translated to nil in Hash.create_from_xml [Rick Olso n]

  <written-on type="date"></written-on> # => { :type => 'date' } # WRONG
  <written-on type="date"></written-on> # => nil # RIGHT

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

* Inflections: don't singularize -ies plurals.  [foamdino@gmail.com, Mark Van Holstyn]

* Update Initializer to use load_once_paths to avoid plugin reloading. References #5852. [Nicholas Seckar]

* Use Array#assoc in ActiveSupport::OrderedHash. [Mauricio Fernandez]

* Greatly increased performance of String.to_json, which speeds up RJS considerably on large pages, fixes #3473 [Shugo Maeda]

* Detect missing_constants calls from removed modules and fail accordingly. [Nicholas Seckar]

* Stop using defined? in Dependencies.qualified_const_defined? since defined? may invoke const_missing. [Nicholas Seckar]

* Dependencies can autoload directories of nested classes. [Jeremy Kemper]
    Example:
      invoice.rb            class Invoice
      invoice/lineitem.rb   class Invoice::Lineitem

* Add Deprecation.silence so that Reloadable does not scold itself. [Nicholas Seckar]

* Add debugging logging to Dependencies. Currently can be enabled with Dependencies.log_activity = true; adding to Initializer and documenting is forthcoming. [Nicholas Seckar]

* Replace Reloadable with improvements to the Dependencies mechanism. [Nicholas Seckar]

* DateTime#to_time gives hour/minute/second resolution.  #5747 [jon.evans@pobox.com]

* attr_internal to support namespacing and deprecation. Like attr_* except backed by internally-named instance variable. Set attr_internal_naming_format to change the format from the default '@_%s'. [Jeremy Kemper]
    # def foo()   @foo__rofl      end
    # def foo=(v) @foo__rofl = v  end
    self.attr_internal_naming_format = '@%s__rofl'
    attr_internal :foo

* Raise fully qualified names upon name errors. #5533 [lars@pinds.com, Nicholas Seckar]

* Add extention to obtain the missing constant from NameError instances. [Nicholas Seckar]

* Thoroughly document inflections.  #5700 [petermichaux@gmail.com]

* Added Module#alias_attribute [Jamis/DHH]. Example:

    class Content < ActiveRecord::Base
      # has a title attribute
    end
 
    class Email < ActiveRecord::Base
      alias_attribute :subject, :title
    end
 
    e = Email.find(1)
    e.title    # => "Superstars"
    e.subject  # => "Superstars"
    e.subject? # => true
    e.subject = "Megastars"
    e.title    # => "Megastars"

* Deprecation: easier to work with warning behavior as procs; default behaviors for each environment so users needn't update env.rb; and testing pleasure with assert_deprecated, assert_not_deprecated. [Jeremy Kemper]
  By default, test prints to $stderr, dev logs, production ignores.
  Provide your own per-environment in e.g. config/environments/development.rb:
    ActiveSupport::Deprecation.behavior = Proc.new { |message| raise message }

* First cut of the Rails Deprecation system.   [Koz]

* Strip boolean XML content before checking for 'true' [Rick Olson]

* Customize default BigDecimal formatting. References #5672 [dave@pragprog.com]

* Correctly convert <foo nil="true"> to nil when using Hash.create_from_xml.  [Rick]

* Optional identity for Enumerable#sum defaults to zero. #5657 [gensym@mac.com]

* HashWithIndifferentAccess shouldn't confuse false and nil. #5601 [shugo@ruby-lang.org]

* Fixed HashWithIndifferentAccess#default #5586 [chris@seagul.co.uk]

* More compatible Hash.create_from_xml. #5523 [nunemaker@gmail.com]

* Added Enumerable#sum for calculating a sum from the elements [DHH, jonathan@daikini.com]. Examples:

    [1, 2, 3].sum
    payments.sum { |p| p.price * p.tax_rate }
    payments.sum(&:price)

  This is instead of payments.inject(0) { |sum, p| sum + p.price }

* Correct and clarify Array#to_sentence docs.  #5458 [brad@madriska.com]

* alias_method_chain preserves method punctuation so foo, foo?, and foo! may be chained with the same feature. [Jeremy Kemper]
    Example:
      alias_method_chain :save!, :validation
    is equivalent to
      alias_method :save_without_validation!, :save!
      alias_method :save!, :save_with_validation!

* Enhance Symbol#to_proc so it works with list objects, such as multi-dimensional arrays. Closes #5295 [nov@yo.rim.or.jp].  Example:

    {1 => "one", 2 => "two", 3 => "three"}.sort_by(&:first).map(&:last)
    #=> ["one", "two", "three"]

* Added Hash.create_from_xml(string) which will create a hash from a XML string and even typecast if possible [DHH]. Example:

    Hash.create_from_xml <<-EOT
      <note>
        <title>This is a note</title>
        <created-at type="date">2004-10-10</created-at>
      </note>
    EOT
  
  ...would return:
  
    { :note => { :title => "This is a note", :created_at => Date.new(2004, 10, 10) } }

* Added Jim Weirich's excellent FlexMock class to vendor (Copyright 2003, 2004 by Jim Weirich (jim@weriichhouse.org)) -- it's not automatically required, though, so require 'flexmock' is still necessary [DHH]

* Fixed that Module#alias_method_chain should work with both foo? foo! and foo at the same time #4954 [anna@wota.jp]

* to_xml fixes, features, and speedup: introduce :dasherize option that converts updated_at to updated-at if true (the existing default); binary columns get encoding="base64" attribute; nil values get nil="true" attribute to distinguish empty values; add type information for float columns; allow arbitrarily deep :include; include SQL type information as the type attribute.  #4989 [Blair Zajac <blair@orcaware.com>]

* Add OrderedHash#values. [Sam Stephenson]

* Added Array#to_s(:db) that'll produce a comma-separated list of ids [DHH]. Example:
    
    Purchase.find(:all, :conditions => "product_id IN (#{shops.products.to_s(:db)})"

* Normalize classify's argument to a String so that it plays nice with Symbols. [Marcel Molina Jr.] 

* Strip out leading schema name in classify. References #5139. [schoenm@earthlink.net]

* Remove Enumerable#first_match since break(value) handles the use case well enough. [Nicholas Seckar]

  Enumerable#first_match was like detect, but instead of returning the matching element, the yielded value returned. For example:
  
    user_xml = adapters(:from => User, :to => Xml).first_match do |adapter|
      adapter.adapt @user
    end
  
  But this is just as easily done with:
  
    user_xml = adapters(:from => User, :to => Xml).each do
      break adapter.adapt(@user)
    end
  
* Make Array#in_groups_of just return the grouped collection if a block isn't given. [Marcel Molina Jr.] 

* Don't destroy a HashWithIndifferentAccess if symbolize_keys! or  stringify_keys! is called on it. Closes #5076. [Marcel Molina Jr., guy.naor@famundo.com]

* Document Module::delegate. #5002 [pergesu@gmail.com]

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

* Strip out punctuation on predicates or bang methods being aliased with alias_method_chain since target?_without_feature is not a valid method name. Add tests for Module#alias_method_chain. [Marcel Molina Jr.]

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

* Allow default options in with_options to be overridden. Closes #4480. [murphy@cYcnus.de] 

* Added Module#alias_method_chain [Jamis Buck]

* Updated to Builder 2.0 [DHH]

* Add Array#split for dividing arrays into one or more subarrays by value or block. [Sam Stephenson]

*1.3.1* (April 6th, 2006)

* Clean paths inside of exception messages and traces. [Nicholas Seckar]

* Add Pathname.clean_within for cleaning all the paths inside of a string. [Nicholas Seckar]

* provide an empty Dependencies::LoadingModule.load which prints deprecation warnings.  Lets 1.0 applications function with .13-style environment.rb.


*1.3.0* (March 27th, 2006)

* When possible, avoid incorrectly obtaining constants from parent modules. Fixes #4221. [Nicholas Seckar]

* Add more tests for dependencies; refactor existing cases. [Nicholas Seckar]

* Move Module#parent and Module#as_load_path into core_ext. Add Module#parent. [Nicholas Seckar]

* Add CachingTools::HashCaching to simplify the creation of nested, autofilling hashes. [Nicholas Seckar]

* Remove a hack intended to avoid unloading the same class twice, but which would not work anyways. [Nicholas Seckar]

* Update Object.subclasses_of to locate nested classes. This affects Object.remove_subclasses_of in that nested classes will now be unloaded. [Nicholas Seckar]

* Update Object.remove_subclasses_of to use Class.remove_class, reducing duplication. [Nicholas Seckar]

* Added Fixnum#seconds for consistency, so you can say 5.minutes + 30.seconds instead of 5.minutes + 30 #4389 [François Beausoleil]

* Added option to String#camelize to generate lower-cased camel case by passing in :lower, like "super_man".camelize(:lower) # => "superMan" [DHH]

* Added Hash#diff to show the difference between two hashes [Chris McGrath]

* Added Time#advance to do precise time time calculations for cases where a month being approximated to 30 days won't do #1860 [Rick Olson]

* Enhance Inflector.underscore to convert '-' into '_' (as the inverse of Inflector.dasherize) [Jamis Buck]

* Switched to_xml to use the xml schema format for datetimes.  This allows the encoding of time zones and should improve operability. [Koz]

* Added a note to the documentation for the Date related Numeric extensions to indicate that they're
approximations and shouldn't be used for critical calculations. [Koz]

* Added Hash#to_xml and Array#to_xml that makes it much easier to produce XML from basic structures [DHH]. Examples:

    { :name => "David", :street_name => "Paulina", :age => 26, :moved_on => Date.new(2005, 11, 15) }.to_xml
    
  ...returns:

      <person>
        <street-name>Paulina</street-name>
        <name>David</name>
        <age type="integer">26</age>
        <moved-on type="date">2005-11-15</moved-on>
      </person>

* Moved Jim Weirich's wonderful Builder from Action Pack to Active Support (it's simply too useful to be stuck in AP) [DHH]

* Fixed that Array#to_sentence will return "" on an empty array instead of ", and" #3842, #4031 [rubyonrails@beautifulpixel.com]

* Add Enumerable#group_by for grouping collections based on the result of some
  block. Useful, for example, for grouping records by date.

  ex.

     latest_transcripts.group_by(&:day).each do |day, transcripts| 
       p "#{day} -> #{transcripts.map(&:class) * ', '}"
     end
     "2006-03-01 -> Transcript"
     "2006-02-28 -> Transcript"
     "2006-02-27 -> Transcript, Transcript"
     "2006-02-26 -> Transcript, Transcript"

  Add Array#in_groups_of, for iterating over an array in groups of a certain
  size.

  ex.

     %w(1 2 3 4 5 6 7).in_groups_of(3) {|g| p g}
     ["1", "2", "3"]
     ["4", "5", "6"]
     ["7", nil, nil]

  [Marcel Molina Jr., Sam Stephenson]

* Added Kernel#daemonize to turn the current process into a daemon that can be killed with a TERM signal [DHH]

* Add 'around' methods to Logger,  to make it easy to log before and after messages for a given block as requested in #3809. [Michael Koziarski]  Example:

  logger.around_info("Start rendering component (#{options.inspect}): ", 
                     "\n\nEnd of component rendering") { yield }

* Added Time#beginning_of_quarter #3607 [cohen.jeff@gmail.com]

* Fix Object.subclasses_of to only return currently defined objects [Jonathan Viney <jonathan@bluewire.net.nz>]

* Fix constantize to properly handle names beginning with '::'. [Nicholas Seckar]

* Make String#last return the string instead of nil when it is shorter than the limit [Scott Barron].

* Added delegation support to Module that allows multiple delegations at once (unlike Forwardable in the stdlib) [DHH]. Example:

    class Account < ActiveRecord::Base
      has_one :subscription
      delegate :free?, :paying?, :to => :subscription
      delegate :overdue?, :to => "subscription.last_payment"
    end
    
    account.free?    # => account.subscription.free?
    account.overdue? # => account.subscription.last_payment.overdue?

* Fix Reloadable to handle the case where a class that has been 'removed' has not yet been garbage collected. [Nicholas Seckar]

* Don't allow Reloadable to be included into Modules.

* Remove LoadingModule. [Nicholas Seckar]

* Add documentation for Reloadable::Subclasses. [Nicholas Seckar]

* Add Reloadable::Subclasses which handles the common case where a base class should not be reloaded, but its subclasses should be. [Nicholas Seckar]

* Further improvements to reloading code [Nicholas Seckar, Trevor Squires]
  
  - All classes/modules which include Reloadable can define reloadable? for fine grained control of reloading
  - Class.remove_class uses Module#parent to access the parent module
  - Class.remove_class expanded to handle multiple classes in a single call
  - LoadingModule.clear! has been removed as it is no longer required
  - Module#remove_classes_including has been removed in favor of Reloadable.reloadable_classes

* Added reusable reloading support through the inclusion of the Relodable module that all subclasses of ActiveRecord::Base, ActiveRecord::Observer, ActiveController::Base, and ActionMailer::Base automatically gets. This means that these classes will be reloaded by the dispatcher when Dependencies.mechanism = :load. You can make your own models reloadable easily:

    class Setting
      include Reloadable
    end
  
  Reloading a class is done by removing its constant which will cause it to be loaded again on the next reference. [DHH]

* Added auto-loading support for classes in modules, so Conductor::Migration will look for conductor/migration.rb and Conductor::Database::Settings will look for conductor/database/settings.rb [Nicholas Seckar]

* Add Object#instance_exec, like instance_eval but passes its arguments to the block.  (Active Support will not override the Ruby 1.9 implementation of this method.) [Sam Stephenson]

* Add Proc#bind(object) for changing a proc or block's self by returning a Method bound to the given object. Based on why the lucky stiff's "cloaker" method. [Sam Stephenson]

* Fix merge and dup for hashes with indifferent access #3404 [kenneth.miller@bitfield.net]

* Fix the requires in option_merger_test to unbreak AS tests. [Sam Stephenson]

* Make HashWithIndifferentAccess#update behave like Hash#update by returning the hash. #3419, #3425 [asnem@student.ethz.ch, JanPrill@blauton.de, Marcel Molina Jr.]

* Add ActiveSupport::JSON and Object#to_json for converting Ruby objects to JSON strings. [Sam Stephenson]

* Add Object#with_options for DRYing up multiple calls to methods having shared options. [Sam Stephenson]  Example:

  ActionController::Routing::Routes.draw do |map|
    # Account routes
    map.with_options(:controller => 'account') do |account|
      account.home   '',       :action => 'dashboard'
      account.signup 'signup', :action => 'new'
      account.logout 'logout', :action => 'logout'
    end
  end

* Introduce Dependencies.warnings_on_first_load setting.  If true, enables warnings on first load of a require_dependency.  Otherwise, loads without warnings.  Disabled (set to false) by default.  [Jeremy Kemper]

* Active Support is warnings-safe.  #1792 [Eric Hodel]

* Introduce enable_warnings counterpart to silence_warnings.  Turn warnings on when loading a file for the first time if Dependencies.mechanism == :load.  Common mistakes such as redefined methods will print warnings to stderr.  [Jeremy Kemper]

* Add Symbol#to_proc, which allows for, e.g. [:foo, :bar].map(&:to_s). [Marcel Molina Jr.]

* Added the following methods [Marcel Molina Jr., Sam Stephenson]:
  * Object#copy_instance_variables_from(object) to copy instance variables from one object to another 
  * Object#extended_by to get an instance's included/extended modules
  * Object#extend_with_included_modules_from(object) to extend an instance with the modules from another instance

*1.2.5* (December 13th, 2005)

* Become part of Rails 1.0

* Rename Version constant to VERSION. #2802 [Marcel Molina Jr.]

* Fixed inflection of perspectives and similar words #1045 [thijs@vandervossen.net]

* Added Fixnum#even? and Fixnum#odd?

* Fixed problem with classes being required twice. Object#const_missing now uses require_dependency to load files. It used to use require_or_load which would cause models to be loaded twice, which was not good for validations and other class methods #971 [Nicholas Seckar]


*1.0.3* (27th March, 2005)

* Fixed Inflector.pluralize to handle capitalized words #932 [Jeremy Kemper]

* Added Object#suppress which allows you to make a saner choice around with exceptions to swallow #980. Example:

    suppress(ZeroDivisionError) { 1/0 }
  
  ...instead of:
  
    1/0 rescue nil # BAD, EVIL, DIRTY.


*1.0.2* (22th March, 2005)

* Added Kernel#returning -- a Ruby-ized realization of the K combinator, courtesy of Mikael Brockman.

    def foo
      returning values = [] do
        values << 'bar'
        values << 'baz'
      end
    end
    
    foo # => ['bar', 'baz']


*1.0.1* (7th March, 2005)

* Fixed Hash#indifferent_access to also deal with include? and fetch and nested hashes #726 [Nicholas Seckar]

* Added Object#blank? -- see http://redhanded.hobix.com/inspect/objectBlank.html #783 [_why the lucky stiff]

* Added inflection rules for "sh" words, like "wish" and "fish" #755 [phillip@pjbsoftware.com]

* Fixed an exception when using Ajax based requests from Safari because Safari appends a \000 to the post body. Symbols can't have \000 in them so indifferent access would throw an exception in the constructor. Indifferent hashes now use strings internally instead. #746 [Tobias Luetke]

* Added String#to_time and String#to_date for wrapping ParseDate


*1.0.0* (24th February, 2005)

* Added TimeZone as the first of a number of value objects that among others Active Record can use rich value objects using composed_of #688 [Jamis Buck]

* Added Date::Conversions for getting dates in different convenient string representations and other objects

* Added Time::Conversions for getting times in different convenient string representations and other objects

* Added Time::Calculations to ask for things like Time.now.tomorrow, Time.now.yesterday, Time.now.months_ago(4) #580 [DP|Flurin]. Examples:

    "Later today"         => now.in(3.hours),
    "Tomorrow morning"    => now.tomorrow.change(:hour => 9),
    "Tomorrow afternoon"  => now.tomorrow.change(:hour => 14),
    "In a couple of days" => now.tomorrow.tomorrow.change(:hour => 9),
    "Next monday"         => now.next_week.change(:hour => 9),
    "In a month"          => now.next_month.change(:hour => 9),
    "In 6 months"         => now.months_since(6).change(:hour => 9),
    "In a year"           => now.in(1.year).change(:hour => 9)

* Upgraded to breakpoint 92 which fixes:

    * overload IRB.parse_opts(), fixes #443
      => breakpoints in tests work even when running them via rake
    * untaint handlers, might fix an issue discussed on the Rails ML
    * added verbose mode to breakpoint_client
    * less noise caused by breakpoint_client by default
    * ignored TerminateLineInput exception in signal handler
      => quiet exit on Ctrl-C

* Fixed Inflector for words like "news" and "series" that are the same in plural and singular #603 [echion], #615 [marcenuc]

* Added Hash#stringify_keys and Hash#stringify_keys!

* Added IndifferentAccess as a way to wrap a hash by a symbol-based store that also can be accessed by string keys

* Added Inflector.constantize to turn "Admin::User" into a reference for the constant Admin::User

* Added that Inflector.camelize and Inflector.underscore can deal with modules like turning "Admin::User" into "admin/user" and back

* Added Inflector.humanize to turn attribute names like employee_salary into "Employee salary". Used by automated error reporting in AR.

* Added availability of class inheritable attributes to the masses #477 [Jeremy Kemper]

    class Foo
      class_inheritable_reader :read_me
      class_inheritable_writer :write_me
      class_inheritable_accessor :read_and_write_me
      class_inheritable_array :read_and_concat_me
      class_inheritable_hash :read_and_update_me
    end

    # Bar gets a clone of (not a reference to) Foo's attributes.
    class Bar < Foo
    end

    Bar.read_and_write_me == Foo.read_and_write_me
    Bar.read_and_write_me = 'bar'
    Bar.read_and_write_me != Foo.read_and_write_me

* Added Inflections as an extension on String, so Inflector.pluralize(Inflector.classify(name)) becomes name.classify.pluralize #476 [Jeremy Kemper]

* Added Byte operations to Numeric, so 5.5.megabytes + 200.kilobytes #461 [Marcel Molina]

* Fixed that Dependencies.reload can't load the same file twice #420 [Kent Sibilev]

* Added Fixnum#ago/until, Fixnum#since/from_now #450 [Jeremy Kemper]

* Added that Inflector now accepts Symbols and Classes by calling .to_s on the word supplied

* Added time unit extensions to Fixnum that'll return the period in seconds, like 2.days + 4.hours.
