Django 1.9.1 release notes
==========================

*Under development*

Django 1.9.1 fixes several bugs in 1.9.

Bugfixes
========

* Fixed ``BaseCache.get_or_set()`` with the ``DummyCache`` backend
  (:ticket:`25840`).

* Fixed a regression in ``FormMixin`` causing forms to be validated twice
  (:ticket:`25548`).

* Fixed a system check crash with nested ``ArrayField``\s (:ticket:`25867`).

* Fixed a state bug when migrating a ``SeparateDatabaseAndState`` operation
  backwards (:ticket:`25896`).

* Fixed a regression in ``CommonMiddleware`` causing ``If-None-Match`` checks
  to always return HTTP 200 (:ticket:`25900`).

* Fixed missing ``varchar/text_pattern_ops`` index on ``CharField`` and
  ``TextField`` respectively when using ``AlterField`` on PostgreSQL
  (:ticket:`25412`).

* Fixed admin's delete confirmation page's summary counts of related objects
  (:ticket:`25883`).

* Added ``from __future__ import unicode_literals`` to the default ``apps.py``
  created by ``startapp`` on Python 2 (:ticket:`25909`). Add this line to your
  own ``apps.py`` files created using Django 1.9 if you want your migrations
  to work on both Python 2 and Python 3.
