rails--rails/activemodel/CHANGELOG.md

• Allows configurable attribute name for #has_secure_password. This still defaults to an attribute named 'password', causing no breaking change. There is a new method #authenticate_XXX where XXX is the configured attribute name, making the existing #authenticate now an alias for this when the attribute is the default 'password'. Example:

  class User < ActiveRecord::Base
      has_secure_password :activation_token, validations: false
  end
  
  user = User.new()
  user.activation_token = "a_new_token"
  user.activation_token_digest                        # => "$2a$10$0Budk0Fi/k2CDm2PEwa3Be..."
  user.authenticate_activation_token('a_new_token')   # => user

• Add config.active_model.i18n_full_message in order to control whether the full_message error format can be overridden at the attribute or model level in the locale files. This is false by default.

• Rails 6 requires Ruby 2.4.1 or newer.
