Django 1.8.4 fixes a security issue and several bugs in 1.8.3.

Bugfixes
========

* Added the ability to serialize values from the newly added
  :class:`~django.db.models.UUIDField` (:ticket:`25019`).

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

* Fixed ``QuerySet.raw()`` so ``InvalidQuery`` is not raised when using the
  ``db_column`` name of a ``ForeignKey`` field with ``primary_key=True``
  (:ticket:`12768`).

* Prevented an exception in ``TestCase.setUpTestData()`` from leaking the
  transaction (:ticket:`25176`).

* Fixed ``has_changed()`` method in ``contrib.postgres.forms.HStoreField``
  (:ticket:`25215`, :ticket:`25233`).

* Fixed the recording of squashed migrations when running the ``migrate``
  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`).

* Prevented ``varchar_patterns_ops`` and ``text_patterns_ops`` indexes for
  ``ArrayField`` (:ticket:`25180`).
