# 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.

## Poprawki błędów

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

- Changed `contrib.gis` to raise `ImproperlyConfigured` rather than `GDALException` if `gdal` isn’t installed, to allow third-party apps to catch that exception (#28178).

- Fixed `django.utils.http.is_safe_url()` crash on invalid IPv6 URLs (#28142).

- Fixed a regression where `Model._state.adding` wasn’t set correctly on multi-table inheritance parent models after saving a child model (#28210).

- 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).

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