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.
