Django 1.11.2 release notes

June 1, 2017

Django 1.11.2 adds a minor feature and fixes several bugs in 1.11.1. Also, the latest string translations from Transifex are incorporated.

Minor feature

The new LiveServerTestCase.port attribute reallows the use case of binding to a specific port following the bind to port zero change in Django 1.11.

Bugfixes

• Added detection for GDAL 2.1 and 2.0, and removed detection for unsupported versions 1.7 and 1.8 (#28181).

• Allowed DjangoJSONEncoder to serialize django.utils.deprecation.CallableBool (#28230).

• Relaxed the validation added in Django 1.11 of the fields in the defaults argument of QuerySet.get_or_create() and update_or_create() to reallow settable model properties (#28222).

• Fixed MultipleObjectMixin.paginate_queryset() crash on Python 2 if the InvalidPage message contains non-ASCII (#28204).

• Prevented Subquery from adding an unnecessary CAST which resulted in invalid SQL (#28199).

• Corrected detection of GDAL 2.1 on Windows (#28181).

• Made date-based generic views return a 404 rather than crash when given an out of range date (#28209).

• Fixed a regression where file_move_safe() crashed when moving files to a CIFS mount (#28170).
