<ul class="simple">
<li>Fixed a crash in MySQL connections where <code class="docutils literal notranslate"><span class="pre">SELECT</span> <span class="pre">@@SQL_AUTO_IS_NULL</span></code>
doesn’t return a result (<a class="reference external" href="https://code.djangoproject.com/ticket/26991">#26991</a>).</li>
<li>Allowed <code class="docutils literal notranslate"><span class="pre">User.is_authenticated</span></code> and <code class="docutils literal notranslate"><span class="pre">User.is_anonymous</span></code> properties to be
compared using <code class="docutils literal notranslate"><span class="pre">==</span></code>, <code class="docutils literal notranslate"><span class="pre">!=</span></code>, and <code class="docutils literal notranslate"><span class="pre">|</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/26988">#26988</a>, <a class="reference external" href="https://code.djangoproject.com/ticket/27154">#27154</a>).</li>
<li>Removed the broken <code class="docutils literal notranslate"><span class="pre">BaseCommand.usage()</span></code> method which was for
<code class="docutils literal notranslate"><span class="pre">optparse</span></code> support (<a class="reference external" href="https://code.djangoproject.com/ticket/27000">#27000</a>).</li>
<li>Fixed a checks framework crash with an empty <code class="docutils literal notranslate"><span class="pre">Meta.default_permissions</span></code>
(<a class="reference external" href="https://code.djangoproject.com/ticket/26997">#26997</a>).</li>
<li>Fixed a regression in the number of queries when using <code class="docutils literal notranslate"><span class="pre">RadioSelect</span></code> with a
<code class="docutils literal notranslate"><span class="pre">ModelChoiceField</span></code> form field (<a class="reference external" href="https://code.djangoproject.com/ticket/27001">#27001</a>).</li>
<li>Fixed a crash if <code class="docutils literal notranslate"><span class="pre">request.META['CONTENT_LENGTH']</span></code> is an empty string
(<a class="reference external" href="https://code.djangoproject.com/ticket/27005">#27005</a>).</li>
<li>Fixed the <code class="docutils literal notranslate"><span class="pre">isnull</span></code> lookup on a <code class="docutils literal notranslate"><span class="pre">ForeignKey</span></code> with its <code class="docutils literal notranslate"><span class="pre">to_field</span></code>
pointing to a <code class="docutils literal notranslate"><span class="pre">CharField</span></code> or pointing to a <code class="docutils literal notranslate"><span class="pre">CharField</span></code> defined with
<code class="docutils literal notranslate"><span class="pre">primary_key=True</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/26983">#26983</a>).</li>
<li>Prevented the <code class="docutils literal notranslate"><span class="pre">migrate</span></code> command from raising
<code class="docutils literal notranslate"><span class="pre">InconsistentMigrationHistory</span></code> in the presence of unapplied squashed
migrations (<a class="reference external" href="https://code.djangoproject.com/ticket/27004">#27004</a>).</li>
<li>Fixed a regression in <code class="docutils literal notranslate"><span class="pre">Client.force_login()</span></code> which required specifying a
<code class="docutils literal notranslate"><span class="pre">backend</span></code> rather than automatically using the first one if multiple
backends are configured (<a class="reference external" href="https://code.djangoproject.com/ticket/27027">#27027</a>).</li>
<li>Made <code class="docutils literal notranslate"><span class="pre">QuerySet.bulk_create()</span></code> 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
(<a class="reference external" href="https://code.djangoproject.com/ticket/27026">#27026</a>).</li>
<li>Fixed crash of <code class="docutils literal notranslate"><span class="pre">django.views.static.serve()</span></code> with <code class="docutils literal notranslate"><span class="pre">show_indexes</span></code> enabled
(<a class="reference external" href="https://code.djangoproject.com/ticket/26973">#26973</a>).</li>
<li>Fixed <code class="docutils literal notranslate"><span class="pre">ClearableFileInput</span></code> to avoid the <code class="docutils literal notranslate"><span class="pre">required</span></code> HTML attribute when
initial data exists (<a class="reference external" href="https://code.djangoproject.com/ticket/27037">#27037</a>).</li>
<li>Fixed annotations with database functions when combined with lookups on
PostGIS (<a class="reference external" href="https://code.djangoproject.com/ticket/27014">#27014</a>).</li>
<li>Reallowed the <code class="docutils literal notranslate"><span class="pre">{%</span> <span class="pre">for</span> <span class="pre">%}</span></code> tag to unpack any iterable (<a class="reference external" href="https://code.djangoproject.com/ticket/27058">#27058</a>).</li>
<li>Made <code class="docutils literal notranslate"><span class="pre">makemigrations</span></code> skip inconsistent history checks on non-default
databases if database routers aren’t in use or if no apps can be migrated
to the database (<a class="reference external" href="https://code.djangoproject.com/ticket/27054">#27054</a>, <a class="reference external" href="https://code.djangoproject.com/ticket/27110">#27110</a>, <a class="reference external" href="https://code.djangoproject.com/ticket/27142">#27142</a>).</li>
<li>Removed duplicated managers in <code class="docutils literal notranslate"><span class="pre">Model._meta.managers</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/27073">#27073</a>).</li>
<li>Fixed <code class="docutils literal notranslate"><span class="pre">contrib.admindocs</span></code> crash when a view is in a class, such as some of
the admin views (<a class="reference external" href="https://code.djangoproject.com/ticket/27018">#27018</a>).</li>
<li>Reverted a few admin checks that checked <code class="docutils literal notranslate"><span class="pre">field.many_to_many</span></code> back to
<code class="docutils literal notranslate"><span class="pre">isinstance(field,</span> <span class="pre">models.ManyToManyField)</span></code> since it turned out the checks
weren’t suitable to be generalized like that (<a class="reference external" href="https://code.djangoproject.com/ticket/26998">#26998</a>).</li>
<li>Added the database alias to the <code class="docutils literal notranslate"><span class="pre">InconsistentMigrationHistory</span></code> message
raised by <code class="docutils literal notranslate"><span class="pre">makemigrations</span></code> and <code class="docutils literal notranslate"><span class="pre">migrate</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/27089">#27089</a>).</li>
<li>Fixed the creation of <code class="docutils literal notranslate"><span class="pre">ContentType</span></code> and <code class="docutils literal notranslate"><span class="pre">Permission</span></code> objects for models
of applications without migrations when calling the <code class="docutils literal notranslate"><span class="pre">migrate</span></code> command with
no migrations to apply (<a class="reference external" href="https://code.djangoproject.com/ticket/27044">#27044</a>).</li>
<li>Included the already applied migration state changes in the <code class="docutils literal notranslate"><span class="pre">Apps</span></code> instance
provided to the <code class="docutils literal notranslate"><span class="pre">pre_migrate</span></code> signal receivers to allow <code class="docutils literal notranslate"><span class="pre">ContentType</span></code>
renaming to be performed on model rename (<a class="reference external" href="https://code.djangoproject.com/ticket/27100">#27100</a>).</li>
<li>Reallowed subclassing <code class="docutils literal notranslate"><span class="pre">UserCreationForm</span></code> without <code class="docutils literal notranslate"><span class="pre">USERNAME_FIELD</span></code> in
<code class="docutils literal notranslate"><span class="pre">Meta.fields</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/27111">#27111</a>).</li>
<li>Fixed a regression in model forms where model fields with a <code class="docutils literal notranslate"><span class="pre">default</span></code> that
didn’t appear in POST data no longer used the <code class="docutils literal notranslate"><span class="pre">default</span></code> (<a class="reference external" href="https://code.djangoproject.com/ticket/27039">#27039</a>).</li>
