Django 1.10.1 release notes
===========================
*Under development*
Django 1.10.1 fixes several bugs in 1.10.
Bugfixes
========
* Fixed a crash in MySQL connections where ``SELECT @@SQL_AUTO_IS_NULL``
doesn't return a result (:ticket:`26991`).
* Allowed ``User.is_authenticated`` and ``User.is_anonymous`` properties to be
compared using ``==`` and ``!=`` (:ticket:`26988`).
* Removed the broken ``BaseCommand.usage()`` method which was for
``optparse`` support (:ticket:`27000`).
* Fixed a checks framework crash with an empty ``Meta.default_permissions``
(:ticket:`26997`).
* Fixed a regression in the number of queries when using ``RadioSelect`` with a
``ModelChoiceField`` form field (:ticket:`27001`).
* Fixed a crash if ``request.META['CONTENT_LENGTH']`` is an empty string
(:ticket:`27005`).
* Fixed the ``isnull`` lookup on a ``ForeignKey`` with its ``to_field``
pointing to a ``CharField`` or pointing to a ``CharField`` defined with
``primary_key=True`` (:ticket:`26983`).
* Prevented the ``migrate`` command from raising
``InconsistentMigrationHistory`` in the presence of unapplied squashed
migrations (:ticket:`27004`).
* Fixed a regression in ``Client.force_login()`` which required specifying a
``backend`` rather than automatically using the first one if multiple
backends are configured (:ticket:`27027`).
* Made ``QuerySet.bulk_create()`` properly initialize model instances on
backends, such as PostgreSQL, that support returning the IDs of the created
records so that many-to-many relationships can be used on the new objects
(:ticket:`27026`).
* Fixed crash of ``django.views.static.serve()`` with ``show_indexes`` enabled
(:ticket:`26973`).
* Fixed ``ClearableFileInput`` to avoid the ``required`` HTML attribute when
initial data exists (:ticket:`27037`).
* Fixed annotations with database functions when combined with lookups on
PostGIS (:ticket:`27014`).
* Reallowed the ``{% for %}`` tag to unpack any iterable (:ticket:`27058`).
* Fixed ``makemigrations`` crash if a database is read-only (:ticket:`27054`).
* Removed duplicated managers in ``Model._meta.managers`` (:ticket:`27073`).
* Fixed ``contrib.admindocs`` crash when a view is in a class, such as some of
the admin views (:ticket:`27018`).
* Reverted a few admin checks that checked ``field.many_to_many`` back to
``isinstance(field, models.ManyToManyField)`` since it turned out the checks
weren't suitable to be generalized like that (:ticket:`26998`).
* Added the database alias to the ``InconsistentMigrationHistory`` message
raised by ``makemigrations`` and ``migrate`` (:ticket:`27089`).
* Fixed the creation of ``ContentType`` and ``Permission`` objects for models
of applications without migrations when calling the ``migrate`` command with
no migrations to apply (:ticket:`27044`).
* Included the already applied migration state changes in the ``Apps`` instance
provided to the ``pre_migrate`` signal receivers to allow ``ContentType``
renaming to be performed on model rename (:ticket:`27100`).
* Reallowed subclassing ``UserCreationForm`` without ``USERNAME_FIELD`` in
``Meta.fields`` (:ticket:`27111`).
* Fixed a regression in model forms where model fields with a ``default`` that
didn't appear in POST data no longer used the ``default`` (:ticket:`27039`).
