We removed the standard set from Alchemy core!
In order to get the standard set back, install the `alchemy-demo_kit` gem.

    def renamed_t_method
      warn = <<-WARN
We renamed alchemy's `t` method override into `_t` to avoid conflicts with Rails own t method!
If you use the `t` method to translate alchemy scoped keys, then you have to use the `_t` method from now on.

    def migrated_to_devise
      warn = <<-WARN
We changed the authentication provider from Authlogic to Devise.

If you are upgrading from an old Alchemy version < 2.5.0, then you have to make changes to your Devise configuration.

1. Run:

$ rails g alchemy:devise

And alter the encryptor to authlogic_sha512
and the stretches value from 10 to 20

# config/initializers/devise.rb
config.stretches = Rails.env.test? ? 1 : 20
config.encryptor = :authlogic_sha512

2. Add the encryptable module to your Alchemy config.yml:

# config/alchemy/config.yml
devise_modules:
  - :database_authenticatable
  - :trackable
  - :validatable
  - :timeoutable
  - :recoverable
  - :encryptable
