Django 1.11.1 release notes

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 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 ` setting in :setting:`DATABASES`.

See Transaction pooling and server-side cursors for more discussion.
