v3.4.0

• enhancements
  • Support added for Rails 4.2. Devise now depends on the responders gem due
    the extraction of the respond_with API from Rails. (by @lucasmazza)
  • The Simple Form templates follow the same change from 3.3.0 by using Log in and adding
    a hint about the minimum password length when validatable is enabled. (by @aried3r)
  • Controller generator added as devise:controllers SCOPE. You can use the -c flag
    to pick which controllers (unlocks, confirmations, etc) you want to generate. (by @Chun-Yang)
  • Removed the hardcoded references for "email" in the flash messages. If you are using
    different attributes as the authentication_keys they will be interpolated in the
    messages instead. (by @timoschilling)
• bug fix
  • Fixed a regression where the devise generator would fail with a ConnectionNotEstablished
    exception when executed inside a mountable engine. (by @lucasmazza)
  • Ensure to return symbols in find_scope! fixing a previous regression from 3.3.0 (by @micat)
  • Ensure all causes of failed login have the same error message (by @pjungwir)
  • The last_attempt_warning now takes effect when generating the unauthenticated
    message for your users. To keep the current behavior, this flag is now true
    by default. (by @lucasmazza)
