* Added a system check warning if the old ``TEMPLATE_*`` settings are defined
  in addition to the new ``TEMPLATES`` setting.

  ``db_column`` name of a ``ForeignKey`` field with ``primary_key=True``
  (:ticket:`12768`).

  command (:ticket:`25231`).

* Moved the :ref:`unsaved model instance assignment data loss check
  <unsaved-model-instance-check-18>` to ``Model.save()`` to allow easier usage
  of in-memory models (:ticket:`25160`).
