We are glad to announce that Devise 3.1.0.rc is out. On this version, we have focused on some security enhancements regarding our defaults and the deprecation of TokenAuthenticatable. This blog post explains the rationale behind those changes and how to upgrade. Devise 3.1.0.rc runs on both Rails 3.2 and Rails 4.0. There is a TL;DR for upgrading at the end of this post. Note: We have yanked 3.1.0.
