Rafael Mendonça França 53954aa476 Move CHANGELOG entry to Active Record
While the type definition is in Active Model the change of behavior will
be only user facing in Active Record so better to put the entry in its
changelog.

## 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.
