-## Rails 5.0.0.beta2 (February 01, 2016) ##
 
-*   No changes.

-
-## Rails 5.0.0.beta1 (December 18, 2015) ##
-
-*   Validate multiple contexts on `valid?` and `invalid?` at once.
-
-    Example:
-
-        class Person
-          include ActiveModel::Validations
-
-          attr_reader :name, :title
-          validates_presence_of :name, on: :create
-          validates_presence_of :title, on: :update
-        end
-
-        person = Person.new
-        person.valid?([:create, :update])    # => false
-        person.errors.messages               # => {:name=>["can't be blank"], :title=>["can't be blank"]}
-
-    *Dmitry Polushkin*
-
-*   Add case_sensitive option for confirmation validator in models.
-
-    *Akshat Sharma*
-
-*   Ensure `method_missing` is called for methods passed to
-    `ActiveModel::Serialization#serializable_hash` that don't exist.
-
-    *Jay Elaraj*
-
-*   Remove `ActiveModel::Serializers::Xml` from core.
-
-    *Zachary Scott*
-
-*   Add `ActiveModel::Dirty#[attr_name]_previously_changed?` and
-    `ActiveModel::Dirty#[attr_name]_previous_change` to improve access
-    to recorded changes after the model has been saved.
-
-    It makes the dirty-attributes query methods consistent before and after
-    saving.
-
-    *Fernando Tapia Rico*
-
-*   Deprecate the `:tokenizer` option for `validates_length_of`, in favor of
-    plain Ruby.
-
-    *Sean Griffin*
-
-*   Deprecate `ActiveModel::Errors#add_on_empty` and `ActiveModel::Errors#add_on_blank`
-    with no replacement.
-
-    *Wojciech Wnętrzak*
-
-*   Deprecate `ActiveModel::Errors#get`, `ActiveModel::Errors#set` and
-    `ActiveModel::Errors#[]=` methods that have inconsistent behavior.
-
-    *Wojciech Wnętrzak*
-
-*   Allow symbol as values for `tokenize` of `LengthValidator`.
-
-    *Kensuke Naito*
-
-*   Assigning an unknown attribute key to an `ActiveModel` instance during initialization
-    will now raise `ActiveModel::AttributeAssignment::UnknownAttributeError` instead of
-    `NoMethodError`.
-
-    Example:
-
-        User.new(foo: 'some value')
-        # => ActiveModel::AttributeAssignment::UnknownAttributeError: unknown attribute 'foo' for User.
-
-    *Eugene Gilburg*
-
-*   Extracted `ActiveRecord::AttributeAssignment` to `ActiveModel::AttributeAssignment`
-    allowing to use it for any object as an includable module.
-
-    Example:
-
-        class Cat
-          include ActiveModel::AttributeAssignment
-          attr_accessor :name, :status
-        end
-
-        cat = Cat.new
-        cat.assign_attributes(name: "Gorby", status: "yawning")
-        cat.name   # => 'Gorby'
-        cat.status # => 'yawning'
-        cat.assign_attributes(status: "sleeping")
-        cat.name   # => 'Gorby'
-        cat.status # => 'sleeping'
-
-    *Bogdan Gusiev*
-
-*   Add `ActiveModel::Errors#details`
-
-    To be able to return type of used validator, one can now call `details`
-    on errors instance.
-
-    Example:
-
-        class User < ActiveRecord::Base
-          validates :name, presence: true
-        end
-
-        user = User.new; user.valid?; user.errors.details
-        => {name: [{error: :blank}]}
-
-    *Wojciech Wnętrzak*
-
-*   Change validates_acceptance_of to accept true by default.
-
-    The default for validates_acceptance_of is now "1" and true.
-    In the past, only "1" was the default and you were required to add
-    accept: true.
-
-*   Remove deprecated `ActiveModel::Dirty#reset_#{attribute}` and
-    `ActiveModel::Dirty#reset_changes`.
-
-    *Rafael Mendonça França*
-
-*   Change the way in which callback chains can be halted.
-
-    The preferred method to halt a callback chain from now on is to explicitly
-    `throw(:abort)`.
-    In the past, returning `false` in an Active Model `before_` callback had
-    the side effect of halting the callback chain.
-    This is not recommended anymore and, depending on the value of the
-    `ActiveSupport.halt_callback_chains_on_return_false` option, will
-    either not work at all or display a deprecation warning.
