  6. 

  7. Django 1.11.1 adds a minor feature and fixes several bugs in 1.11.

  8. 

  9. Allowed disabling server-side cursors on PostgreSQL

  10. ===================================================

  11. 

  12. The change in Django 1.11 to make :meth:`.QuerySet.iterator()` use server-side

  13. cursors on PostgreSQL prevents running Django with PgBouncer in transaction

  14. pooling mode. To reallow that, use the :setting:`DISABLE_SERVER_SIDE_CURSORS

  15. <DATABASE-DISABLE_SERVER_SIDE_CURSORS>` setting in :setting:`DATABASES`.

  16. 

  17. See :ref:`transaction-pooling-server-side-cursors` for more discussion.

  19. Bugfixes

  20. ========

  21. 

  22. * Made migrations respect ``Index``’s ``name`` argument. If you created a

  23.   named index with Django 1.11, ``makemigrations`` will create a migration to

  24.   recreate the index with the correct name (:ticket:`28051`).

  25. 

  26. * Fixed a crash when using a ``__icontains`` lookup on a ``ArrayField``

  27.   (:ticket:`28038`).

  28.

  30.   argument (:ticket:`28042`).

  31.

  42.   ``_session_cache`` isn't populated (:ticket:`28066`).

  43.

  52. 

  53. * Restored the output of the ``class`` attribute in the ``<ul>`` of widgets

  56. 

  57. * Fixed crash in ``BaseGeometryWidget.subwidgets()`` (:ticket:`28039`).

  58. 

  59. * Fixed exception reraising in ORM query execution when ``cursor.execute()``

  61. 

  62. * Fixed a regression where ``CheckboxSelectMultiple``, ``NullBooleanSelect``,

  63.   ``RadioSelect``, ``SelectMultiple``, and ``Select`` localized option values

  64.   (:ticket:`28075`).

  65. 

  66. * Corrected the stack level of unordered queryset pagination warnings

  67.   (:ticket:`28109`).

  68. 

  69. * Fixed a regression causing incorrect queries for ``__in`` subquery lookups

  70.   when models use ``ForeignKey.to_field`` (:ticket:`28101`).

  71. 

  72. * Fixed crash when overriding the template of

  73.   ``django.views.static.directory_index()`` (:ticket:`28122`).

  74.

  102. * Corrected the return type of ``ArrayField(CITextField())`` values retrieved

  103.   from the database (:ticket:`28161`).
