rails--rails/activesupport/CHANGELOG.md

Rails 4.0.0 (unreleased)

• An optional block can be passed to Hash#deep_merge. The block will be invoked for each duplicated key and used to resolve the conflict. Pranas Kiziela

• ActiveSupport::Deprecation is now a class. It is possible to create an instance of deprecator. Backwards compatibility has been preserved.

  You can choose which instance of the deprecator will be used.

  deprecate :method_name, :deprecator => deprecator_instance
  

  You can use ActiveSupport::Deprecation in your gem.

  require 'active_support/deprecation'
  require 'active_support/core_ext/module/deprecation'
  
  class MyGem
    def self.deprecator
      ActiveSupport::Deprecation.new('2.0', 'MyGem')
    end
  
    def old_method
    end
  
    def new_method
    end
  
    deprecate :old_method => :new_method, :deprecator => deprecator
  end
  
  MyGem.new.old_method
  # => DEPRECATION WARNING: old_method is deprecated and will be removed from MyGem 2.0 (use new_method instead). (called from <main> at file.rb:18)

• ERB::Util.html_escape encodes single quote as #39. Decimal form has better support in old browsers. Kalys Osmonov

• ActiveSupport::Callbacks: deprecate monkey patch of object callbacks. Using the #filter method like this:

  before_filter MyFilter.new
  
  class MyFilter
    def filter(controller)
    end
  end
  

  Is now deprecated with recommendation to use the corresponding filter type (#before, #after or #around):

  before_filter MyFilter.new
  
  class MyFilter
    def before(controller)
    end
  end

• An optional block can be passed to HashWithIndifferentAccess#update and #merge. The block will be invoked for each duplicated key, and used to resolve the conflict, thus replicating the behaviour of the corresponding methods on the Hash class.
