1.1.2

Backwards incompatible changes:

• Activation view no longer contains username. If you override
  userena/templates/userena/emails/activation_email_message.txt and
  userena/templates/userena/emails/confirmation_email_message_new.txt be sure
  to remove username from the URL.

1.1

Backwards incompatible changes:

• Userena now requires Django >= 1.3 because of the use of class based views.

1.0.1

Backwards incompatible changes:

• Removed the user relationship outside UserenaBaseProfile model. This
  allows the user to define it's own relationship and fixes a conflict while
  running manage.py test. To migrate, place the user field inside your
  profile model, instead of inheriting it from the abstract class.
