All adhoc MAC applications have been updated to use HMAC, using SHA1 to
generate unique keys for each application based on the SECRET_KEY, which is
common practice for this situation. In all cases, backwards compatibility
with existing hashes has been maintained, aiming to phase this out as per
the normal deprecation process. In this way, under most normal
circumstances the old hashes will have expired (e.g. by session expiration
etc.) before they become invalid.
In the case of the messages framework and the cookie backend, which was
already using HMAC, there is the possibility of a backwards incompatibility
if the SECRET_KEY is shorter than the default 50 bytes, but the low
likelihood and low impact meant compatibility code was not worth it.
All known instances where tokens/hashes were compared using simple string
equality, which could potentially open timing based attacks, have also been
fixed using a constant-time comparison function.
There are no known practical attacks against the existing implementations,
so these security improvements will not be backported.

This is BACKWARDS INCOMPATIBLE if you were using the completely undocumented moderation view from 1.1. That view's been removed in favor of the admin actions.
Thanks, Thejaswi Puthraya.

The is a potentially backwards-incompatible change for users already relying on the internals of comment moderaration. To wit:
* The moderation system now listens to the new `comment_will_be_posted`/`comment_was_posted` signals instead of `pre/post_save`. This means that import request-based information is available to moderation as it should be.
* Some experimental code from `django.contrib.comments.moderation` has been removed. It was never intended to be merged into Django, and was completely untested and likely buggy.

This began life as (part of) James Bennett's comment-utils app, and was adapted to be part of Django by Thejaswi Puthraya and Jannis Leidel. Thanks, all!

This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering. For the first case, django.test.TransactionTestCase should be used. TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case. See the testing doc for full details.
Many thanks to:
* Marc Remolt for the initial proposal and implementation.
* Luke Plant for initial testing and improving the implementation.
* Ramiro Morales for feedback and help with tracking down a mysterious PostgreSQL issue.
* Eric Holscher for feedback regarding the effect of the change on the Ellington testsuite.
* Russell Keith-Magee for guidance and feedback from beginning to end.

Much of this work was done by Thejaswi Puthraya as part of Google's Summer of Code project; much thanks to him for the work, and to them for the program.
This is a backwards-incompatible change; see the upgrading guide in docs/ref/contrib/comments/upgrade.txt for instructions if you were using the old comments system.
