Django 1.11.7 -> 2.0

2.0

========================

December 2, 2017

Welcome to Django 2.0!

These release notes cover the :ref:new features <whats-new-2.0>, as well as some :ref:backwards incompatible changes <backwards-incompatible-2.0> you'll want to be aware of when upgrading from Django 1.11 or earlier. We've :ref:dropped some features<removed-features-2.0> that have reached the end of their deprecation cycle, and we've :ref:begun the deprecation process for some features <deprecated-features-2.0>.

This release starts Django's use of a :ref:loose form of semantic versioning <internal-release-cadence>, but there aren't any major backwards incompatible changes that might be expected of a 2.0 release. Upgrading should be a similar amount of effort as past feature releases.

See the :doc:/howto/upgrade-version guide if you're updating an existing project.

Python compatibility

Django 2.0 supports Python 3.4, 3.5, and 3.6. We highly recommend and only officially support the latest release of each series.

The Django 1.11.x series is the last to support Python 2.7.

Django 2.0 will be the last release series to support Python 3.4. If you plan a deployment of Python 3.4 beyond the end-of-life for Django 2.0 (April 2019), stick with Django 1.11 LTS (supported until April 2020) instead. Note, however, that the end-of-life for Python 3.4 is March 2019.

Third-party library support for older version of Django

Following the release of Django 2.0, we suggest that third-party app authors drop support for all versions of Django prior to 1.11. At that time, you should be able to run your package's tests using python -Wd so that deprecation warnings do appear. After making the deprecation warning fixes, your app should be compatible with Django 2.0.

.. _whats-new-2.0:

What's new in Django 2.0

Simplified URL routing syntax

The new :func:django.urls.path() function allows a simpler, more readable URL routing syntax. For example, this example from previous Django releases::

url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),

could be written as::

path('articles/<int:year>/', views.year_archive),

The new syntax supports type coercion of URL parameters. In the example, the view will receive the year keyword argument as an integer rather than as a string. Also, the URLs that will match are slightly less constrained in the rewritten example. For example, the year 10000 will now match since the year integers aren't constrained to be exactly four digits long as they are in the regular expression.

The django.conf.urls.url() function from previous versions is now available as :func:django.urls.re_path. The old location remains for backwards compatibility, without an imminent deprecation. The old django.conf.urls.include() function is now importable from django.urls so you can use from django.urls import include, path, re_path in your URLconfs.

The :doc:/topics/http/urls document is rewritten to feature the new syntax and provide more details.

Mobile-friendly contrib.admin

The admin is now responsive and supports all major mobile devices. Older browsers may experience varying levels of graceful degradation.

Window expressions

The new :class:~django.db.models.expressions.Window expression allows adding an OVER clause to querysets. You can use :ref:window functions <window-functions> and :ref:aggregate functions <aggregation-functions> in the expression.

Minor features

:mod:django.contrib.admin

* The new :attr:`.ModelAdmin.autocomplete_fields` attribute and
 :meth:`.ModelAdmin.get_autocomplete_fields` method allow using an
 `Select2 <https://select2.org>`_ search widget for ``ForeignKey`` and
 ``ManyToManyField``.

:mod:`django.contrib.auth`

• The default iteration count for the PBKDF2 password hasher is increased from 36,000 to 100,000.

:mod:django.contrib.gis

* Added MySQL support for the
 :class:`~django.contrib.gis.db.models.functions.AsGeoJSON` function,
 :class:`~django.contrib.gis.db.models.functions.GeoHash` function,
 :class:`~django.contrib.gis.db.models.functions.IsValid` function,
 :lookup:`isvalid` lookup, and :ref:`distance lookups <distance-lookups>`.

* Added the :class:`~django.contrib.gis.db.models.functions.Azimuth` and
 :class:`~django.contrib.gis.db.models.functions.LineLocatePoint` functions,
 supported on PostGIS and SpatiaLite.

* Any :class:`~django.contrib.gis.geos.GEOSGeometry` imported from GeoJSON now
 has its SRID set.

* Added the :attr:`.OSMWidget.default_zoom` attribute to customize the map's
 default zoom level.

* Made metadata readable and editable on rasters through the
 :attr:`~django.contrib.gis.gdal.GDALRaster.metadata`,
 :attr:`~django.contrib.gis.gdal.GDALRaster.info`, and
 :attr:`~django.contrib.gis.gdal.GDALBand.metadata` attributes.

* Allowed passing driver-specific creation options to
 :class:`~django.contrib.gis.gdal.GDALRaster` objects using ``papsz_options``.

* Allowed creating :class:`~django.contrib.gis.gdal.GDALRaster` objects in
 GDAL's internal virtual filesystem. Rasters can now be :ref:`created from and
 converted to binary data <gdal-raster-vsimem>` in-memory.

* The new :meth:`GDALBand.color_interp()
 <django.contrib.gis.gdal.GDALBand.color_interp>` method returns the color
 interpretation for the band.

:mod:`django.contrib.postgres`

• The new distinct argument for :class:~django.contrib.postgres.aggregates.ArrayAgg determines if concatenated values will be distinct.

• The new :class:~django.contrib.postgres.functions.RandomUUID database function returns a version 4 UUID. It requires use of PostgreSQL's pgcrypto extension which can be activated using the new :class:~django.contrib.postgres.operations.CryptoExtension migration operation.

• :class:django.contrib.postgres.indexes.GinIndex now supports the fastupdate and gin_pending_list_limit parameters.

• The new :class:~django.contrib.postgres.indexes.GistIndex class allows creating GiST indexes in the database. The new :class:~django.contrib.postgres.operations.BtreeGistExtension migration operation installs the btree_gist extension to add support for operator classes that aren't built-in.

• :djadmin:inspectdb can now introspect JSONField and various RangeField\s (django.contrib.postgres must be in INSTALLED_APPS).

:mod:django.contrib.sitemaps

* Added the ``protocol`` keyword argument to the
 :class:`~django.contrib.sitemaps.GenericSitemap` constructor.

Cache

• cache.set_many() now returns a list of keys that failed to be inserted. For the built-in backends, failed inserts can only happen on memcached.

File Storage

* :meth:`File.open() <django.core.files.File.open>` can be used as a context
 manager, e.g. ``with file.open() as f:``.

Forms

• The new date_attrs and time_attrs arguments for :class:~django.forms.SplitDateTimeWidget and :class:~django.forms.SplitHiddenDateTimeWidget allow specifying different HTML attributes for the DateInput and TimeInput (or hidden) subwidgets.

• The new :meth:Form.errors.get_json_data() <django.forms.Form.errors.get_json_data> method returns form errors as a dictionary suitable for including in a JSON response.

Generic Views

* The new :attr:`.ContextMixin.extra_context` attribute allows adding context
 in ``View.as_view()``.

Management Commands

• :djadmin:inspectdb now translates MySQL's unsigned integer columns to PositiveIntegerField or PositiveSmallIntegerField.

• The new :option:makemessages --add-location option controls the comment format in PO files.

• :djadmin:loaddata can now :ref:read from stdin <loading-fixtures-stdin>.

• The new :option:diffsettings --output option allows formatting the output in a unified diff format.

• On Oracle, :djadmin:inspectdb can now introspect AutoField if the column is created as an identity column.

• On MySQL, :djadmin:dbshell now supports client-side TLS certificates.

Migrations

* The new :option:`squashmigrations --squashed-name` option allows naming the
 squashed migration.

Models

• The new :class:~django.db.models.functions.StrIndex database function finds the starting index of a string inside another string.

• On Oracle, AutoField and BigAutoField are now created as identity columns_.

  .. _identity columns: https://docs.oracle.com/database/121/DRDAA/migr_tools_feat.htmDRDAA109

• The new chunk_size parameter of :meth:.QuerySet.iterator controls the number of rows fetched by the Python database client when streaming results from the database. For databases that don't support server-side cursors, it controls the number of results Django fetches from the database adapter.

• :meth:.QuerySet.earliest, :meth:.QuerySet.latest, and :attr:Meta.get_latest_by <django.db.models.Options.get_latest_by> now allow ordering by several fields.

• Added the :class:~django.db.models.functions.ExtractQuarter function to extract the quarter from :class:~django.db.models.DateField and :class:~django.db.models.DateTimeField, and exposed it through the :lookup:quarter lookup.

• Added the :class:~django.db.models.functions.TruncQuarter function to truncate :class:~django.db.models.DateField and :class:~django.db.models.DateTimeField to the first day of a quarter.

• Added the :attr:~django.db.models.Index.db_tablespace parameter to class-based indexes.

• If the database supports a native duration field (Oracle and PostgreSQL), :class:~django.db.models.functions.Extract now works with :class:~django.db.models.DurationField.

• Added the of argument to :meth:.QuerySet.select_for_update(), supported on PostgreSQL and Oracle, to lock only rows from specific tables rather than all selected tables. It may be helpful particularly when :meth:~.QuerySet.select_for_update() is used in conjunction with :meth:~.QuerySet.select_related().

• The new field_name parameter of :meth:.QuerySet.in_bulk allows fetching results based on any unique model field.

• :meth:.CursorWrapper.callproc() now takes an optional dictionary of keyword parameters, if the backend supports this feature. Of Django's built-in backends, only Oracle supports it.

• The new :meth:connection.execute_wrapper() <django.db.backends.base.DatabaseWrapper.execute_wrapper> method allows :doc:installing wrappers around execution of database queries </topics/db/instrumentation>.

• The new filter argument for built-in aggregates allows :ref:adding different conditionals <conditional-aggregation> to multiple aggregations over the same fields or relations.

• Added support for expressions in :attr:Meta.ordering <django.db.models.Options.ordering>.

• The new named parameter of :meth:.QuerySet.values_list allows fetching results as named tuples.

• The new :class:.FilteredRelation class allows adding an ON clause to querysets.

Pagination

* Added :meth:`Paginator.get_page() <django.core.paginator.Paginator.get_page>`
 to provide the documented pattern of handling invalid page numbers.

Requests and Responses

• The :djadmin:runserver Web server supports HTTP 1.1.

Templates

* To increase the usefulness of :meth:`.Engine.get_default` in third-party
 apps, it now returns the first engine if multiple ``DjangoTemplates`` engines
 are configured in ``TEMPLATES`` rather than raising ``ImproperlyConfigured``.

* Custom template tags may now accept keyword-only arguments.

Tests

• Added threading support to :class:~django.test.LiveServerTestCase.

• Added settings that allow customizing the test tablespace parameters for Oracle: :setting:DATAFILE_SIZE, :setting:DATAFILE_TMP_SIZE, :setting:DATAFILE_EXTSIZE, and :setting:DATAFILE_TMP_EXTSIZE.

Validators

* The new :class:`.ProhibitNullCharactersValidator` disallows the null
 character in the input of the :class:`~django.forms.CharField` form field
 and its subclasses. Null character input was observed from vulnerability
 scanning tools. Most databases silently discard null characters, but
 psycopg2 2.7+ raises an exception when trying to save a null character to
 a char/text field with PostgreSQL.

.. _backwards-incompatible-2.0:

Backwards incompatible changes in 2.0
=====================================

Removed support for bytestrings in some places
----------------------------------------------

To support native Python 2 strings, older Django versions had to accept both
bytestrings and unicode strings. Now that Python 2 support is dropped,
bytestrings should only be encountered around input/output boundaries (handling
of binary fields or HTTP streams, for example). You might have to update your
code to limit bytestring usage to a minimum, as Django no longer accepts
bytestrings in certain code paths.

For example, ``reverse()`` now uses ``str()`` instead of ``force_text()`` to
coerce the ``args`` and ``kwargs`` it receives, prior to their placement in
the URL. For bytestrings, this creates a string with an undesired ``b`` prefix
as well as additional quotes (``str(b'foo')`` is ``"b'foo'"``). To adapt, call
``decode()`` on the bytestring before passing it to ``reverse()``.

Database backend API
--------------------

This section describes changes that may be needed in third-party database
backends.

* The ``DatabaseOperations.datetime_cast_date_sql()``,
 ``datetime_cast_time_sql()``, ``datetime_trunc_sql()``,
 ``datetime_extract_sql()``, and ``date_interval_sql()`` methods now return
 only the SQL to perform the operation instead of SQL and a list of
 parameters.

* Third-party database backends should add a ``DatabaseWrapper.display_name``
 attribute with the name of the database that your backend works with. Django
 may use it in various messages, such as in system checks.

* The first argument of ``SchemaEditor._alter_column_type_sql()`` is now
 ``model`` rather than ``table``.

* The first argument of ``SchemaEditor._create_index_name()`` is now
 ``table_name`` rather than ``model``.

* To enable ``FOR UPDATE OF`` support, set
 ``DatabaseFeatures.has_select_for_update_of = True``. If the database
 requires that the arguments to ``OF`` be columns rather than tables, set
 ``DatabaseFeatures.select_for_update_of_column = True``.

* To enable support for :class:`~django.db.models.expressions.Window`
 expressions, set ``DatabaseFeatures.supports_over_clause`` to ``True``. You
 may need to customize the ``DatabaseOperations.window_start_rows_start_end()``
 and/or ``window_start_range_start_end()`` methods.

* Third-party database backends should add a
 ``DatabaseOperations.cast_char_field_without_max_length`` attribute with the
 database data type that will be used in the
 :class:`~django.db.models.functions.Cast` function for a ``CharField`` if the
 ``max_length`` argument isn't provided.

* The first argument of ``DatabaseCreation._clone_test_db()`` and
 ``get_test_db_clone_settings()`` is now ``suffix`` rather
 than ``number`` (in case you want to rename the signatures in your backend
 for consistency). ``django.test`` also now passes those values as strings
 rather than as integers.

* Third-party database backends should add a
 ``DatabaseIntrospection.get_sequences()`` method based on the stub in
 ``BaseDatabaseIntrospection``.

Dropped support for Oracle 11.2
-------------------------------

The end of upstream support for Oracle 11.2 is Dec. 2020. Django 1.11 will be
supported until April 2020 which almost reaches this date. Django 2.0
officially supports Oracle 12.1+.

Default MySQL isolation level is read committed
-----------------------------------------------

MySQL's default isolation level, repeatable read, may cause data loss in
typical Django usage. To prevent that and for consistency with other databases,
the default isolation level is now read committed. You can use the
:setting:`DATABASES` setting to :ref:`use a different isolation level
<mysql-isolation-level>`, if needed.

:attr:`AbstractUser.last_name <django.contrib.auth.models.User.last_name>` ``max_length`` increased to 150
----------------------------------------------------------------------------------------------------------

A migration for :attr:`django.contrib.auth.models.User.last_name` is included.
If you have a custom user model inheriting from ``AbstractUser``, you'll need
to generate and apply a database migration for your user model.

If you want to preserve the 30 character limit for last names, use a custom
form::

   from django.contrib.auth.forms import UserChangeForm

   class MyUserChangeForm(UserChangeForm):
       last_name = forms.CharField(max_length=30, required=False)

If you wish to keep this restriction in the admin when editing users, set
``UserAdmin.form`` to use this form::

   from django.contrib.auth.admin import UserAdmin
   from django.contrib.auth.models import User

   class MyUserAdmin(UserAdmin):
       form = MyUserChangeForm

   admin.site.unregister(User)
   admin.site.register(User, MyUserAdmin)

``QuerySet.reverse()`` and ``last()`` are prohibited after slicing
------------------------------------------------------------------

Calling ``QuerySet.reverse()`` or ``last()`` on a sliced queryset leads to
unexpected results due to the slice being applied after reordering. This is
now prohibited, e.g.::

   >>> Model.objects.all()[:2].reverse()
   Traceback (most recent call last):
   ...
   TypeError: Cannot reverse a query once a slice has been taken.

Form fields no longer accept optional arguments as positional arguments
-----------------------------------------------------------------------

To help prevent runtime errors due to incorrect ordering of form field
arguments, optional arguments of built-in form fields are no longer accepted
as positional arguments. For example::

   forms.IntegerField(25, 10)

raises an exception and should be replaced with::

   forms.IntegerField(max_value=25, min_value=10)

``call_command()`` validates the options it receives
----------------------------------------------------

``call_command()`` now validates that the argument parser of the command being
called defines all of the options passed to ``call_command()``.

For custom management commands that use options not created using
``parser.add_argument()``, add a ``stealth_options`` attribute on the command::

   class MyCommand(BaseCommand):
       stealth_options = ('option_name', ...)

Indexes no longer accept positional arguments
---------------------------------------------

For example::

   models.Index(['headline', '-pub_date'], 'index_name')

raises an exception and should be replaced with::

   models.Index(fields=['headline', '-pub_date'], name='index_name')

Foreign key constraints are now enabled on SQLite
-------------------------------------------------

This will appear as a backwards-incompatible change (``IntegrityError:
FOREIGN KEY constraint failed``) if attempting to save an existing model
instance that's violating a foreign key constraint.

Foreign keys are now created with ``DEFERRABLE INITIALLY DEFERRED`` instead of
``DEFERRABLE IMMEDIATE``. Thus, tables may need to be rebuilt to recreate
foreign keys with the new definition, particularly if you're using a pattern
like this::

   from django.db import transaction

   with transaction.atomic():
       Book.objects.create(author_id=1)
       Author.objects.create(id=1)

If you don't recreate the foreign key as ``DEFERRED``, the first ``create()``
would fail now that foreign key constraints are enforced.

Backup your database first! After upgrading to Django 2.0, you can then
rebuild tables using a script similar to this::

   from django.apps import apps
   from django.db import connection

   for app in apps.get_app_configs():
       for model in app.get_models(include_auto_created=True):
           if model._meta.managed and not (model._meta.proxy or model._meta.swapped):
               for base in model.__bases__:
                   if hasattr(base, '_meta'):
                       base._meta.local_many_to_many = []
               model._meta.local_many_to_many = []
               with connection.schema_editor() as editor:
                   editor._remake_table(model)

This script hasn't received extensive testing and needs adaption for various
cases such as multiple databases. Feel free to contribute improvements.

In addition, because of a table alteration limitation of SQLite, it's prohibited
to perform :class:`~django.db.migrations.operations.RenameModel` and
:class:`~django.db.migrations.operations.RenameField` operations on models or
fields referenced by other models in a transaction. In order to allow migrations
containing these operations to be applied, you must set the
``Migration.atomic`` attribute to ``False``.

Miscellaneous
-------------

* The ``SessionAuthenticationMiddleware`` class is removed. It provided no
 functionality since session authentication is unconditionally enabled in
 Django 1.10.

* The default HTTP error handlers (``handler404``, etc.) are now callables
 instead of dotted Python path strings. Django favors callable references
 since they provide better performance and debugging experience.

* :class:`~django.views.generic.base.RedirectView` no longer silences
 ``NoReverseMatch`` if the ``pattern_name`` doesn't exist.

* When :setting:`USE_L10N` is off, :class:`~django.forms.FloatField` and
 :class:`~django.forms.DecimalField` now respect :setting:`DECIMAL_SEPARATOR`
 and :setting:`THOUSAND_SEPARATOR` during validation. For example, with the
 settings::

    USE_L10N = False
    USE_THOUSAND_SEPARATOR = True
    DECIMAL_SEPARATOR = ','
    THOUSAND_SEPARATOR = '.'

 an input of ``"1.345"`` is now converted to ``1345`` instead of ``1.345``.

* Subclasses of :class:`~django.contrib.auth.models.AbstractBaseUser` are no
 longer required to implement ``get_short_name()`` and ``get_full_name()``.
 (The base implementations that raise ``NotImplementedError`` are removed.)
 ``django.contrib.admin`` uses these methods if implemented but doesn't
 require them. Third-party apps that use these methods may want to adopt a
 similar approach.

* The ``FIRST_DAY_OF_WEEK`` and ``NUMBER_GROUPING`` format settings are now
 kept as integers in JavaScript and JSON i18n view outputs.

* :meth:`~django.test.TransactionTestCase.assertNumQueries` now ignores
 connection configuration queries. Previously, if a test opened a new database
 connection, those queries could be included as part of the
 ``assertNumQueries()`` count.

* The default size of the Oracle test tablespace is increased from 20M to 50M
 and the default autoextend size is increased from 10M to 25M.

* To improve performance when streaming large result sets from the database,
 :meth:`.QuerySet.iterator` now fetches 2000 rows at a time instead of 100.
 The old behavior can be restored using the ``chunk_size`` parameter. For
 example::

     Book.objects.iterator(chunk_size=100)

* Providing unknown package names in the ``packages`` argument of the
 :class:`~django.views.i18n.JavaScriptCatalog` view now raises ``ValueError``
 instead of passing silently.

* A model instance's primary key now appears in the default ``Model.__str__()``
 method, e.g. ``Question object (1)``.

* ``makemigrations`` now detects changes to the model field ``limit_choices_to``
 option. Add this to your existing migrations or accept an auto-generated
 migration for fields that use it.

* Performing queries that require :ref:`automatic spatial transformations
 <automatic-spatial-transformations>` now raises ``NotImplementedError``
 on MySQL instead of silently using non-transformed geometries.

* ``django.core.exceptions.DjangoRuntimeWarning`` is removed. It was only used
 in the cache backend as an intermediate class in ``CacheKeyWarning``'s
 inheritance of ``RuntimeWarning``.

* Renamed ``BaseExpression._output_field`` to ``output_field``. You may need
 to update custom expressions.

* In older versions, forms and formsets combine their ``Media`` with widget
 ``Media`` by concatenating the two. The combining now tries to :ref:`preserve
 the relative order of elements in each list <form-media-asset-order>`.
 ``MediaOrderConflictWarning`` is issued if the order can't be preserved.

* ``django.contrib.gis.gdal.OGRException`` is removed. It's been an alias for
 ``GDALException`` since Django 1.8.

* Support for GEOS 3.3.x is dropped.

* The way data is selected for ``GeometryField`` is changed to improve
 performance, and in raw SQL queries, those fields must now be wrapped in
 ``connection.ops.select``. See the :ref:`Raw queries note<gis-raw-sql>` in
 the GIS tutorial for an example.

.. _deprecated-features-2.0:

Features deprecated in 2.0
==========================

``context`` argument of ``Field.from_db_value()`` and ``Expression.convert_value()``
------------------------------------------------------------------------------------

The ``context`` argument of ``Field.from_db_value()`` and
``Expression.convert_value()`` is unused as it's always an empty dictionary.
The signature of both methods is now::

   (self, value, expression, connection)

instead of::

   (self, value, expression, connection, context)

Support for the old signature in custom fields and expressions remains until
Django 3.0.

Miscellaneous
-------------

* The ``django.db.backends.postgresql_psycopg2`` module is deprecated in favor
 of ``django.db.backends.postgresql``. It's been an alias since Django 1.9.
 This only affects code that imports from the module directly. The
 ``DATABASES`` setting can still use
 ``'django.db.backends.postgresql_psycopg2'``, though you can simplify that by
 using the ``'django.db.backends.postgresql'`` name added in Django 1.9.

* ``django.shortcuts.render_to_response()`` is deprecated in favor of
 :func:`django.shortcuts.render`. ``render()`` takes the same arguments
 except that it also requires a ``request``.

* The ``DEFAULT_CONTENT_TYPE`` setting is deprecated. It doesn't interact well
 well with third-party apps and is obsolete since HTML5 has mostly superseded
 XHTML.

* ``HttpRequest.xreadlines()`` is deprecated in favor of iterating over the
 request.

* The ``field_name`` keyword argument to :meth:`.QuerySet.earliest` and
 :meth:`.QuerySet.latest` is deprecated in favor of passing the field
 names as arguments. Write ``.earliest('pub_date')`` instead of
 ``.earliest(field_name='pub_date')``.

.. _removed-features-2.0:

Features removed in 2.0
=======================

These features have reached the end of their deprecation cycle and are removed
in Django 2.0.

See :ref:`deprecated-features-1.9` for details on these changes, including how
to remove usage of these features.

* The ``weak`` argument to ``django.dispatch.signals.Signal.disconnect()`` is
 removed.

* ``django.db.backends.base.BaseDatabaseOperations.check_aggregate_support()``
 is removed.

* The ``django.forms.extras`` package is removed.

* The ``assignment_tag`` helper is removed.

* The ``host`` argument to ``SimpleTestCase.assertsRedirects()`` is removed.
 The compatibility layer which allows absolute URLs to be considered equal to
 relative ones when the path is identical is also removed.

* ``Field.rel`` and ``Field.remote_field.to`` are removed.

* The ``on_delete`` argument for ``ForeignKey`` and ``OneToOneField`` is now
 required in models and migrations. Consider squashing migrations so that you
 have less of them to update.

* ``django.db.models.fields.add_lazy_relation()`` is removed.

* When time zone support is enabled, database backends that don't support time
 zones no longer convert aware datetimes to naive values in UTC anymore when
 such values are passed as parameters to SQL queries executed outside of the
 ORM, e.g. with ``cursor.execute()``.

* ``django.contrib.auth.tests.utils.skipIfCustomUser()`` is removed.

* The ``GeoManager`` and ``GeoQuerySet`` classes are removed.

* The ``django.contrib.gis.geoip`` module is removed.

* The ``supports_recursion`` check for template loaders is removed from:

 * ``django.template.engine.Engine.find_template()``
 * ``django.template.loader_tags.ExtendsNode.find_template()``
 * ``django.template.loaders.base.Loader.supports_recursion()``
 * ``django.template.loaders.cached.Loader.supports_recursion()``

* The ``load_template`` and ``load_template_sources`` template loader methods
 are removed.

* The ``template_dirs`` argument for template loaders is removed:

 * ``django.template.loaders.base.Loader.get_template()``
 * ``django.template.loaders.cached.Loader.cache_key()``
 * ``django.template.loaders.cached.Loader.get_template()``
 * ``django.template.loaders.cached.Loader.get_template_sources()``
 * ``django.template.loaders.filesystem.Loader.get_template_sources()``

* ``django.template.loaders.base.Loader.__call__()`` is removed.

* Support for custom error views that don't accept an ``exception`` parameter
 is removed.

* The ``mime_type`` attribute of ``django.utils.feedgenerator.Atom1Feed`` and
 ``django.utils.feedgenerator.RssFeed`` is removed.

* The ``app_name`` argument to ``include()`` is removed.

* Support for passing a 3-tuple (including ``admin.site.urls``) as the first
 argument to ``include()`` is removed.

* Support for setting a URL instance namespace without an application namespace
 is removed.

* ``Field._get_val_from_obj()`` is removed.

* ``django.template.loaders.eggs.Loader`` is removed.

* The ``current_app`` parameter to the ``contrib.auth`` function-based views is
 removed.

* The ``callable_obj`` keyword argument to
 ``SimpleTestCase.assertRaisesMessage()`` is removed.

* Support for the ``allow_tags`` attribute on ``ModelAdmin`` methods is
 removed.

* The ``enclosure`` keyword argument to ``SyndicationFeed.add_item()`` is
