Django 1.8.6 release notes
==========================
*November 4, 2015*
Django 1.8.6 adds official support for Python 3.5 and fixes several bugs in
1.8.5.
Bugfixes
========
* Fixed a regression causing ``ModelChoiceField`` to ignore
``prefetch_related()`` on its queryset (:ticket:`25496`).
* Allowed "mode=memory" in SQLite test database name if supported
(:ticket:`12118`).
* Fixed system check crash on ``ForeignKey`` to abstract model
(:ticket:`25503`).
* Fixed incorrect queries when you have multiple ``ManyToManyField``\s on
different models that have the same field name, point to the same model, and
have their reverse relations disabled (:ticket:`25545`).
* Allowed filtering over a ``RawSQL`` annotation (:ticket:`25506`).
* Made the ``Concat`` database function idempotent on SQLite (:ticket:`25517`).
* Avoided a confusing stack trace when starting :djadmin:`runserver` with an
invalid :setting:`INSTALLED_APPS` setting (:ticket:`25510`). This regression
appeared in 1.8.5 as a side effect of fixing :ticket:`24704`.
* Made deferred models use their proxied model's ``_meta.apps`` for caching
and retrieval (:ticket:`25563`). This prevents any models generated in data
migrations using ``QuerySet.defer()`` from leaking to test and application
code.
* Fixed a typo in the name of the ``strictly_above`` PostGIS lookup
(:ticket:`25592`).
* Fixed crash with ``contrib.postgres.forms.SplitArrayField`` and
``IntegerField`` on invalid value (:ticket:`25597`).
* Added a helpful error message when Django and South migrations exist in the
same directory (:ticket:`25618`).
* Fixed a regression in ``URLValidator`` that allowed URLs with consecutive
dots in the domain section (like ``http://example..com/``) to pass
(:ticket:`25620`).
* Fixed a crash with ``GenericRelation`` and
``BaseModelAdmin.to_field_allowed`` (:ticket:`25622`).
