+      This Authlogic configuration option (%s) is deprecated. Use normal
+      ActiveRecord validations instead. For example, instead of the Authlogic
+      method validates_length_of_email_field_options, you can use
+
+          validates :email, length: { ... }
+
+      These deprecated Authlogic methods will be removed in the next major version.
