=========================== Django 1.11.2 release notes =========================== *Under development* Django 1.11.2 fixes several bugs in 1.11.1. Bugfixes ======== * Added detection for GDAL 2.1 and 2.0, and removed detection for unsupported versions 1.7 and 1.8 (:ticket:`28181`). * Changed ``contrib.gis`` to raise ``ImproperlyConfigured`` rather than ``GDALException`` if ``gdal`` isn't installed, to allow third-party apps to catch that exception (:ticket:`28178`). * Fixed ``django.utils.http.is_safe_url()`` crash on invalid IPv6 URLs (:ticket:`28142`). * Fixed regression causing pickling of model fields to crash (:ticket:`28188`). * Fixed ``django.contrib.auth.authenticate()`` when multiple authentication backends don't accept a positional ``request`` argument (:ticket:`28207`). * Fixed introspection of index field ordering on PostgreSQL (:ticket:`28197`). * Fixed a regression where ``Model._state.adding`` wasn't set correctly on multi-table inheritance parent models after saving a child model (:ticket:`28210`). * Allowed ``DjangoJSONEncoder`` to serialize ``django.utils.deprecation.CallableBool`` (:ticket:`28230`).
