Note that this\nmeans that the admin application will depend on the messages\ncontext processor.

Authentication backends will need to support the AnonymousUser class\nbeing passed to all methods dealing with permissions. The\nsupports_anonymous_user variable will no longer be checked and can be\nremoved from custom backends.
