  arguments (fixture names) (:ticket:`24571`).

  ``get_language_bidi()`` when translations are deactivated (:ticket:`24569`).

* Fixed :djadmin:`squashmigrations` command when using
  :class:`~django.db.migrations.operations.SeparateDatabaseAndState`
  (:ticket:`24278`).

* Stripped microseconds from ``datetime`` values when using an older version of
  the MySQLdb DB API driver as it does not support fractional seconds
  (:ticket:`24584`).

* Fixed a migration crash when altering
  :class:`~django.db.models.ManyToManyField`\s (:ticket:`24513`).

* Fixed a crash with ``QuerySet.update()`` on foreign keys to one-to-one fields
  (:ticket:`24578`).

* Fixed a regression in the model detail view of
  :mod:`~django.contrib.admindocs` when a model has a reverse foreign key
  relation (:ticket:`24624`).

* Prevented arbitrary file inclusions in :mod:`~django.contrib.admindocs`
  (:ticket:`24625`).

* Fixed a crash with ``QuerySet.update()`` on foreign keys to instances with
  ``uuid`` primary keys (:ticket:`24611`).

  remove usage of referencing views by dotted path in
  :func:`~django.conf.urls.url` which is deprecated in Django 1.8
  (:ticket:`24635`).

* Fixed queries where an expression was referenced in ``order_by()``, but wasn't
