• attr_accessible and friends now accepts :as as option to specify a role Josh Kalderimis

• Add support for proc or lambda as an option for InclusionValidator, ExclusionValidator, and FormatValidator Prem Sichanugrist

  You can now supply Proc, lambda, or anything that respond to #call in those validations, and it will be called with current record as an argument. That given proc or lambda must returns an object which respond to #include? for InclusionValidator and ExclusionValidator, and returns a regular expression object for FormatValidator.

• Added ActiveModel::MassAssignmentSecurity Eric Chapweske, Josh Kalderimis

• JSON supports a custom root option: to_json(:root => 'custom') #4515 Jatinder Singh

    klass.add_observer(self)
    klass.class_eval 'def after_find() end' unless klass.respond_to?(:after_find)
  end

• Extracted from Active Record and Active Resource.
