  8. 

  9. Bugfixes

  10. ========

  11. 

  12. * Fixed ``BaseCache.get_or_set()`` with the ``DummyCache`` backend

  13.   (:ticket:`25840`).

  14. 

  15. * Fixed a regression in ``FormMixin`` causing forms to be validated twice

  16.   (:ticket:`25548`, :ticket:`26018`).

  17. 

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

  19. 

  20. * Fixed a state bug when migrating a ``SeparateDatabaseAndState`` operation

  21.   backwards (:ticket:`25896`).

  22. 

  23. * Fixed a regression in ``CommonMiddleware`` causing ``If-None-Match`` checks

  24.   to always return HTTP 200 (:ticket:`25900`).

  25. 

  26. * Fixed missing ``varchar/text_pattern_ops`` index on ``CharField`` and

  27.   ``TextField`` respectively when using ``AlterField`` on PostgreSQL

  28.   (:ticket:`25412`).

  29. 

  30. * Fixed admin's delete confirmation page's summary counts of related objects

  31.   (:ticket:`25883`).

  32. 

  33. * Added ``from __future__ import unicode_literals`` to the default ``apps.py``

  34.   created by ``startapp`` on Python 2 (:ticket:`25909`). Add this line to your

  35.   own ``apps.py`` files created using Django 1.9 if you want your migrations

  36.   to work on both Python 2 and Python 3.

  37. 

  38. * Prevented ``QuerySet.delete()`` from crashing on MySQL when querying across

  39.   relations (:ticket:`25882`).

  40. 

  41. * Fixed evaluation of zero-length slices of ``QuerySet.values()``

  42.   (:ticket:`25894`).

  43. 

  44. * Fixed a state bug when using an ``AlterModelManagers`` operation

  45.   (:ticket:`25852`).

  46. 

  47. * Fixed ``TypedChoiceField`` change detection with nullable fields

  48.   (:ticket:`25942`).

  49. 

  50. * Fixed incorrect timezone warnings in custom admin templates that don't have

  51.   a ``data-admin-utc-offset`` attribute in the ``body`` tag.

  52.   (:ticket:`25845`).

  53. 

  54. * Fixed a regression which prevented using a language not in Django's default

  55.   language list (:setting:`LANGUAGES`) (:ticket:`25915`).

  56. 

  57. * Avoided hiding some exceptions, like an invalid ``INSTALLED_APPS`` setting,

  58.   behind ``AppRegistryNotReady`` when starting ``runserver`` (:ticket:`25510`).

  59.   This regression appeared in 1.8.5 as a side effect of fixing :ticket:`24704`

  60.   and by mistake the fix wasn't applied to the ``stable/1.9.x`` branch.

  61. 

  62. * Fixed ``migrate --fake-initial`` detection of many-to-many tables

  63.   (:ticket:`25922`).

  64. 

  65. * Restored the functionality of the admin's ``list_editable`` add and change

  66.   buttons (:ticket:`25903`).

  67. 

  68. * Fixed ``isnull`` query lookup for ``ForeignObject``

  69.   (:ticket:`25972`).

  70. 

  71. * Fixed a regression in the admin which ignored line breaks in read-only fields

  72.   instead of converting them to ``<br>`` (:ticket:`25465`).

  73. 

  74. * Fixed incorrect object reference in

  75.   ``SingleObjectMixin.get_context_object_name()`` (:ticket:`26006`).

  76. 

  77. * Made ``loaddata`` skip disabling and enabling database constraints when it

  78.   doesn't load any fixtures (:ticket:`23372`).

  79. 

  80. * Restored ``contrib.auth`` hashers compatibility with ``py-bcrypt``

  81.   (:ticket:`26016`).

  82. 

  83. * Fixed a crash in ``QuerySet.values()/values_list()`` after an ``annotate()``

  84.   and ``order_by()`` when ``values()/values_list()`` includes a field not in

  85.   the ``order_by()`` (:ticket:`25316`).
