rails--rails/activemodel/CHANGELOG.md

• Add ActiveModel::AttributeSet#values_for_database

  Returns attributes with values for assignment to the database.

  Chris Salzberg

• Fix delegation in ActiveModel::Type::Registry#lookup and ActiveModel::Type.lookup

  Passing a last positional argument {} would be incorrectly considered as keyword argument.

  Benoit Daloze

• Cache and re-use generated attribute methods.

  Generated methods with identical implementations will now share their instruction sequences leading to reduced memory retention, and slightly faster load time.

  Jean Boussier

• Add in: range parameter to numericality validator.

  Michal Papis

• Add locale argument to ActiveModel::Name#initialize to be used to generate the singular, plural, route_key and singular_route_key values.
