ActiveRecord dirty tracking that compares every attribute to it's value before type cast and marks all changes detected as changed attributes. This makes it possible to detect `user.name.upcase!` `user.roles << 'some_role'` and similar implicit changes. To make it automatic on `save`, this module sets up a `before_validation` callback when included into a model.
