------------------
- **Breaking:** ``Revision.comment`` 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()``.
(RamezIssac).
- **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`` (ivissani).
- Added ``request_creates_revision`` hook to ``RevisionMiddleware`` and ``views.create_revision``. (kklingenberg).
- Added ``revision_request_creates_revision`` hook to ``views.RevisionMixinView``. (kklingenberg).
- Added ``--meta`` flag to ``./manage.py createrevisions`` (massover).
- Fixed bug when reverting deleted nested inlines (Primož Kariž).
- Added tests for django 2.1 (claudep).
