1.11.1

===========================

May 6, 2017

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

Allowed disabling server-side cursors on PostgreSQL

The change in Django 1.11 to make :meth:.QuerySet.iterator() use server-side
cursors on PostgreSQL prevents running Django with pgBouncer in transaction
pooling mode. To reallow that, use the :setting:DISABLE_SERVER_SIDE_CURSORS <DATABASE-DISABLE_SERVER_SIDE_CURSORS> setting in :setting:DATABASES.

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

  named index with Django 1.11, makemigrations will create a migration to
  recreate the index with the correct name (:ticket:28051).

  (:ticket:28038).

  from the database (:ticket:28161).

• Fixed QuerySet.prefetch_related() crash when fetching relations in nested
  Prefetch objects (:ticket:27554).
