Active Model

Active Record

• Handle commas in Sqlite3 default function definitions.

  Stephen Margheim

• Fixes validates_associated raising an exception when configured with a
  singular association and having index_nested_attribute_errors enabled.

  Martin Spickermann

• The constant ActiveRecord::ImmutableRelation has been deprecated because
  we want to reserve that name for a stronger sense of "immutable relation".
  Please use ActiveRecord::UnmodifiableRelation instead.
