- Update to version 3.0.0:
* Breaking: 'Revision.commment' now contains the raw JSON change
message generated by django admin, rather than a string.
Accesing 'Revision.comment' directly is no longer recommended.
Instead, use 'Revision.get_comment()'.
* Breaking: django-reversion now uses '_base_manager' to
calculate deleted models, not '_default_manager'. This change
will only affect models that perform default filtering in their
'_default_manager'
* Added 'request_creates_revision' hook to 'RevisionMiddleware'
and 'views.create_revision'.
* Added 'revision_request_creates_revision' hook to
'views.RevisionMixinView'.
* Added '--meta' flag to './manage.py createrevisions'
* Fixed bug when reverting deleted nested inlines
* Added tests for django 2.1
