Changelogs

coverage 4.4.1 -> 4.4.2

4.4.2

---

• Support for Python 3.7. In some cases, class and module docstrings are no
  longer counted in statement totals, which could slightly change your total
  results.

• Specifying both --source and --include no longer silently ignores the
  include setting, instead it displays a warning. Thanks, Loïc Dachary. Closes
  issue 265_ and issue 101_.

• Fixed a race condition when saving data and multiple threads are tracing
  (issue 581_). It could produce a "dictionary changed size during iteration"
  RuntimeError. I believe this mostly but not entirely fixes the race
  condition. A true fix would likely be too expensive. Thanks, Peter Baughman
  for the debugging, and Olivier Grisel for the fix with tests.

• Configuration values which are file paths will now apply tilde-expansion,
  closing issue 589_.

• Now secondary config files like tox.ini and setup.cfg can be specified
  explicitly, and prefixed sections like [coverage:run] will be read. Fixes
  issue 588_.

• Be more flexible about the command name displayed by help, fixing
  issue 600_. Thanks, Ben Finney.

django-debug-toolbar -> 1.9.1

1.9

---

This version is compatible with Django 2.0 and requires Django 1.8 or
later.

Bugfixes

• The profiling panel now escapes reported data resulting in valid HTML.
• Many minor cleanups and bugfixes.

1.8

---

This version is compatible with Django 1.11 and requires Django 1.8 or
later.

Backwards incompatible changes

• debug_toolbar.middleware.show_toolbar (the default value of setting
  SHOW_TOOLBAR_CALLBACK) no longer returns False for AJAX requests.
  This is to allow reusing the SHOW_TOOLBAR_CALLBACK function to verify
  access to panel views requested via AJAX. Projects defining a custom
  SHOW_TOOLBAR_CALLBACK should remove checks for AJAX requests in order to
  continue to allow access to these panels.

Features

• New decorator debug_toolbar.decorators.require_show_toolbar prevents
  unauthorized access to decorated views by checking SHOW_TOOLBAR_CALLBACK
  every request. Unauthorized access results in a 404.
• The SKIP_TEMPLATE_PREFIXES setting allows skipping templates in
  the templates panel. Template-based form widgets' templates are
  skipped by default to avoid panel sizes going into hundreds of
  megabytes of HTML.

Bugfixes

• All views are now decorated with
  debug_toolbar.decorators.require_show_toolbar preventing unauthorized
  access.
• The templates panel now reuses contexts' pretty printed version which
  makes the debug toolbar usable again with Django 1.11's template-based
  forms rendering.
• Long SQL statements are now forcibly wrapped to fit on the screen.

1.7

---

Bugfixes

• Recursive template extension is now understood.
• Deprecation warnings were fixed.
• The SQL panel uses HMAC instead of simple hashes to verify that SQL
  statements have not been changed. Also, the handling of bytes and text
  for hashing has been hardened. Also, a bug with Python's division
  handling has been fixed for improved Python 3 support.
• An error with django-jinja has been fixed.
• A few CSS classes have been prefixed with djdt- to avoid
  conflicting class names.

1.6

---

The debug toolbar was adopted by jazzband.

Removed features

• Support for automatic setup has been removed as it was frequently
  problematic. Installation now requires explicit setup. The
  DEBUG_TOOLBAR_PATCH_SETTINGS setting has also been removed as it is now
  unused. See the :doc:installation documentation <installation> for details.

Bugfixes

• The DebugToolbarMiddleware now also supports Django 1.10's MIDDLEWARE
  setting.

1.5

---

This version is compatible with Django 1.10 and requires Django 1.8 or later.

Support for Python 3.2 is dropped.

Bugfixes

• Restore compatibility with sqlparse ≥ 0.2.0.
• Add compatibility with Bootstrap 4, Pure CSS, MDL, etc.
• Improve compatibility with RequireJS / AMD.
• Improve the UI slightly.
• Fix invalid (X)HTML.

1.4

---

This version is compatible with Django 1.9 and requires Django 1.7 or later.

New features

• New panel method :meth:debug_toolbar.panels.Panel.generate_stats allows panels
  to only record stats when the toolbar is going to be inserted into the
  response.

Bugfixes

• Response time for requests of projects with numerous media files has
  been improved.

1.3

---

This is the first version compatible with Django 1.8.

New features

• A new panel is available: Template Profiler.
• The SHOW_TOOLBAR_CALLBACK accepts a callable.
• The toolbar now provides a :ref:javascript-api.

Bugfixes

• The toolbar handle cannot leave the visible area anymore when the toolbar is
  collapsed.
• The root level logger is preserved.
• The RESULTS_CACHE_SIZE setting is taken into account.
• CSS classes are prefixed with djdt- to prevent name conflicts.
• The private copy of jQuery no longer registers as an AMD module on sites
  that load RequireJS.

1.2

---

New features

• The JQUERY_URL setting defines where the toolbar loads jQuery from.

Bugfixes

• The toolbar now always loads a private copy of jQuery in order to avoid
  using an incompatible version. It no longer attemps to integrate with AMD.

This private copy is available in djdt.jQuery. Third-party panels are
encouraged to use it because it should be as stable as the toolbar itself.

1.1

---

This is the first version compatible with Django 1.7.

New features

• The SQL panel colors queries depending on the stack level.
• The Profiler panel allows configuring the maximum depth.

Bugfixes

• Support languages where lowercase and uppercase strings may have different
  lengths.
• Allow using cursor as context managers.
• Make the SQL explain more helpful on SQLite.
• Various JavaScript improvements.

Deprecated features

• The INTERCEPT_REDIRECTS setting is superseded by the more generic
  DISABLE_PANELS.

1.0

---

This is the first stable version of the Debug Toolbar!

It includes many new features and performance improvements as well a few
backwards-incompatible changes to make the toolbar easier to deploy, use,
extend and maintain in the future.

You're strongly encouraged to review the installation and configuration docs
and redo the setup in your projects.

Third-party panels will need to be updated to work with this version.

factory-boy -> 2.9.2

2.9.2

---

Bugfix:

• Fix declaration corruption bug when a factory defined foo__bar__baz=1 and a caller
  provided a foo__bar=x parameter at call time: this got merged into the factory's base
  declarations.

2.9.1

---

Bugfix:

• Fix packaging issues (see Tag formatter documentation zestsoftware/zest.releaser#212)
• Don't crash when debugging PostGenerationDeclaration

2.9.0

---

This version brings massive changes to the core engine, thus reducing the number of
corner cases and weird behaviourrs.

New:

• :issue:275: factory.fuzzy and factory.faker now use the same random seed.
• Add :class:factory.Maybe, which chooses among two possible declarations based
  on another field's value (powers the :class:~factory.Trait feature).
• :class:~factory.PostGenerationMethodCall only allows to pass one positional argument; use keyword arguments for
  extra parameters.

Deprecation:

• factory.fuzzy.get_random_state is deprecated, factory.random.get_random_state should be used instead.
• factory.fuzzy.set_random_state is deprecated, factory.random.set_random_state should be used instead.
• factory.fuzzy.reseed_random is deprecated, factory.random.reseed_random should be used instead.

• Add support for random-yet-realistic values through fake-factory <https://pypi.python.org/pypi/fake-factory>_,
  through the :class:factory.Faker class.
• :class:factory.Iterator no longer begins iteration of its argument at import time,
  thus allowing to pass in a lazy iterator such as a Django queryset
  (i.e factory.Iterator(models.MyThingy.objects.all())).
• Simplify imports for ORM layers, now available through a simple factory import,
  at factory.alchemy.SQLAlchemyModelFactory / factory.django.DjangoModelFactory / factory.mongoengine.MongoEngineFactory.

Bugfix:

• Avoid issues when using :meth:factory.django.mute_signals on a base factory class (see :issue:183).
• Fix limitations of :class:factory.StubFactory, that can now use :class:factory.SubFactory and co (see :issue:131).

Deprecation:

• Remove deprecated features from :ref:v2.4.0
• Remove the auto-magical sequence setup (based on the latest primary key value in the database) for Django and SQLAlchemy;
  this relates to issues :issue:170, :issue:153, :issue:111, :issue:103, :issue:92, :issue:78. See FactoryBoy/factory_boy@13d310f for technical details.

.. warning:: Version 2.5.0 removes the 'auto-magical sequence setup' bug-and-feature.
This could trigger some bugs when tests expected a non-zero sequence reference.

Upgrading
"""""""""

.. warning:: Version 2.5.0 removes features that were marked as deprecated in :ref:v2.4.0 <v2.4.0>.

All FACTORY_*-style attributes are now declared in a class Meta: section:

.. code-block:: python

Old-style, deprecated

class MyFactory(factory.Factory):
FACTORY_FOR = models.MyModel
FACTORY_HIDDEN_ARGS = ['a', 'b', 'c']

New-style

class MyFactory(factory.Factory):
class Meta:
model = models.MyModel
exclude = ['a', 'b', 'c']

A simple shell command to upgrade the code would be:

.. code-block:: sh

sed -i: inplace update
grep -l: only file names, not matching lines

sed -i 's/FACTORY_FOR =/class Meta:\n model =/' $(grep -l FACTORY_FOR $(find . -name '*.py'))

This takes care of all FACTORY_FOR occurences; the files containing other attributes to rename can be found with grep -R FACTORY .

2.4.1

---

Bugfix:

• Fix overriding deeply inherited attributes (set in one factory, overridden in a subclass, used in a sub-sub-class).

2.4.0

• Add :class:~factory.fuzzy.FuzzyFloat (:issue:124)
• Declare target model and other non-declaration fields in a class Meta section.

Deprecation:

• Use of FACTORY_FOR and other FACTORY class-level attributes is deprecated and will be removed in 2.5.
  Those attributes should now declared within the :class:class Meta <factory.FactoryOptions> attribute:

 For :class:`factory.Factory`:

 * Rename :attr:`~factory.Factory.FACTORY_FOR` to :attr:`~factory.FactoryOptions.model`
 * Rename :attr:`~factory.Factory.ABSTRACT_FACTORY` to :attr:`~factory.FactoryOptions.abstract`

2.2.1

---

Bugfix:

• Fixed sequence counter for :class:~factory.django.DjangoModelFactory when a factory
  inherits from another factory relating to an abstract model.

2.2.0

---

Bugfix:

• Removed duplicated :class:~factory.alchemy.SQLAlchemyModelFactory lurking in :mod:factory
  (:issue:83)
• Properly handle sequences within object inheritance chains.
  If FactoryA inherits from FactoryB, and their associated classes share the same link,
  sequence counters will be shared (:issue:93)
• Properly handle nested :class:~factory.SubFactory overrides

New:

  fields defined in wrapping factories.
• Move :class:~factory.django.DjangoModelFactory and :class:~factory.mogo.MogoFactory
  to their own modules (:mod:factory.django and :mod:factory.mogo)
• Add the :meth:~factory.Factory.reset_sequence classmethod to :class:~factory.Factory
  to ease resetting the sequence counter for a given factory.
• Add debug messages to factory logger.
• Add a :meth:~factory.Iterator.reset method to :class:~factory.Iterator (:issue:63)

Upgrading
"""""""""

This version deprecates a few magic or undocumented features.
All warnings will turn into errors starting from v2.0.0.

  factory.SubFactory('some.module.Symbol')
• Replace factory.InfiniteIterator(iterable) with factory.Iterator(iterable)

pylint 1.7.2 -> 1.8.1

1.8

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

Release date: 2017-12-15

• Respect disable=... in config file when running with --py3k.

• New warning shallow-copy-environ added

 Shallow copy of os.environ doesn't work as people may expect. os.environ
 is not a dict object but rather a proxy object, so any changes made
 on copy may have unexpected effects on os.environ

 Instead of copy.copy(os.environ) method os.environ.copy() should be
 used.

 See https://bugs.python.org/issue15373 for details.

 This is emitted for function definitions
 in which keyword arguments are placed before variable
 positional arguments (*args).

 This may lead to args list getting modified if keyword argument's value
 is not provided in the function call assuming it will take default value
 provided in the definition.

• The invalid-name check contains the name of the template that caused the failure

pytest 3.2.2 -> 3.3.1

3.3.1

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

Bug Fixes

• Fix issue about -p no:<plugin> having no effect. (2920 <https://github.com/pytest-dev/pytest/issues/2920>_)

• Fix regression with warnings that contained non-strings in their arguments in
  Python 2. (2956 <https://github.com/pytest-dev/pytest/issues/2956>_)

• Always escape null bytes when setting PYTEST_CURRENT_TEST. (2957 <https://github.com/pytest-dev/pytest/issues/2957>_)

• Fix ZeroDivisionError when using the testmon plugin when no tests
  were actually collected. (2971 <https://github.com/pytest-dev/pytest/issues/2971>_)

• Bring back TerminalReporter.writer as an alias to
  TerminalReporter._tw. This alias was removed by accident in the 3.3.0
  release. (2984 <https://github.com/pytest-dev/pytest/issues/2984>_)

• The pytest-capturelog plugin is now also blacklisted, avoiding errors when
  running pytest with it still installed. (3004 <https://github.com/pytest-dev/pytest/issues/3004>_)

Improved Documentation

• Fix broken link to plugin pytest-localserver. (2963 <https://github.com/pytest-dev/pytest/issues/2963>_)

Trivial/Internal Changes

• Update github "bugs" link in CONTRIBUTING.rst (2949 <https://github.com/pytest-dev/pytest/issues/2949>_)

3.3.0

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

Deprecations and Removals

• Pytest no longer supports Python 2.6 and 3.3. Those Python versions
  are EOL for some time now and incur maintenance and compatibility costs on
  the pytest core team, and following up with the rest of the community we
  decided that they will no longer be supported starting on this version. Users
  which still require those versions should pin pytest to <3.3. (2812 <https://github.com/pytest-dev/pytest/issues/2812>_)

• Remove internal _preloadplugins() function. This removal is part of the
  pytest_namespace() hook deprecation. (2636 <https://github.com/pytest-dev/pytest/issues/2636>_)

• Internally change CallSpec2 to have a list of marks instead of a broken
  mapping of keywords. This removes the keywords attribute of the internal
  CallSpec2 class. (2672 <https://github.com/pytest-dev/pytest/issues/2672>_)

• Remove ParameterSet.deprecated_arg_dict - its not a public api and the lack
  of the underscore was a naming error. (2675 <https://github.com/pytest-dev/pytest/issues/2675>_)

• Remove the internal multi-typed attribute Node._evalskip and replace it
  with the boolean Node._skipped_by_mark. (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• The params list passed to pytest.fixture is now for
  all effects considered immutable and frozen at the moment of the pytest.fixture
  call. Previously the list could be changed before the first invocation of the fixture
  allowing for a form of dynamic parametrization (for example, updated from command-line options),
  but this was an unwanted implementation detail which complicated the internals and prevented
  some internal cleanup. See issue 2959 <https://github.com/pytest-dev/pytest/issues/2959>_
  for details and a recommended workaround.

Features

• pytest_fixture_post_finalizer hook can now receive a request
  argument. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• Replace the old introspection code in compat.py that determines the available
  arguments of fixtures with inspect.signature on Python 3 and
  funcsigs.signature on Python 2. This should respect __signature__
  declarations on functions. (2267 <https://github.com/pytest-dev/pytest/issues/2267>_)

• Report tests with global pytestmark variable only once. (2549 <https://github.com/pytest-dev/pytest/issues/2549>_)

• Now pytest displays the total progress percentage while running tests. The
  previous output style can be set by configuring the console_output_style
  setting to classic. (2657 <https://github.com/pytest-dev/pytest/issues/2657>_)

• Match warns signature to raises by adding match keyword. (2708 <https://github.com/pytest-dev/pytest/issues/2708>_)

• Pytest now captures and displays output from the standard logging module.
  The user can control the logging level to be captured by specifying options
  in pytest.ini, the command line and also during individual tests using
  markers. Also, a caplog fixture is available that enables users to test
  the captured log during specific tests (similar to capsys for example).
  For more information, please see the logging docs <https://docs.pytest.org/en/latest/logging.html>. This feature was
  introduced by merging the popular pytest-catchlog <https://pypi.org/project/pytest-catchlog/> plugin, thanks to Thomas Hisch <https://github.com/thisch>. Be advised that during the merging the
  backward compatibility interface with the defunct pytest-capturelog has
  been dropped. (2794 <https://github.com/pytest-dev/pytest/issues/2794>)

• Add allow_module_level kwarg to pytest.skip(), enabling to skip the
  whole module. (2808 <https://github.com/pytest-dev/pytest/issues/2808>_)

• Allow setting file_or_dir, -c, and -o in PYTEST_ADDOPTS. (2824 <https://github.com/pytest-dev/pytest/issues/2824>_)

• Return stdout/stderr capture results as a namedtuple, so out and
  err can be accessed by attribute. (2879 <https://github.com/pytest-dev/pytest/issues/2879>_)

• Add capfdbinary, a version of capfd which returns bytes from
  readouterr(). (2923 <https://github.com/pytest-dev/pytest/issues/2923>_)

• Add capsysbinary a version of capsys which returns bytes from
  readouterr(). (2934 <https://github.com/pytest-dev/pytest/issues/2934>_)

• Implement feature to skip setup.py files when run with
  --doctest-modules. (502 <https://github.com/pytest-dev/pytest/issues/502>_)

Bug Fixes

• Resume output capturing after capsys/capfd.disabled() context manager.
  (1993 <https://github.com/pytest-dev/pytest/issues/1993>_)

• pytest_fixture_setup and pytest_fixture_post_finalizer hooks are now
  called for all conftest.py files. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• If an exception happens while loading a plugin, pytest no longer hides the
  original traceback. In python2 it will show the original traceback with a new
  message that explains in which plugin. In python3 it will show 2 canonized
  exceptions, the original exception while loading the plugin in addition to an
  exception that PyTest throws about loading a plugin. (2491 <https://github.com/pytest-dev/pytest/issues/2491>_)

• capsys and capfd can now be used by other fixtures. (2709 <https://github.com/pytest-dev/pytest/issues/2709>_)

• Internal pytester plugin properly encodes bytes arguments to
  utf-8. (2738 <https://github.com/pytest-dev/pytest/issues/2738>_)

• testdir now uses use the same method used by tmpdir to create its
  temporary directory. This changes the final structure of the testdir
  directory slightly, but should not affect usage in normal scenarios and
  avoids a number of potential problems. (2751 <https://github.com/pytest-dev/pytest/issues/2751>_)

• Pytest no longer complains about warnings with unicode messages being
  non-ascii compatible even for ascii-compatible messages. As a result of this,
  warnings with unicode messages are converted first to an ascii representation
  for safety. (2809 <https://github.com/pytest-dev/pytest/issues/2809>_)

• Change return value of pytest command when --maxfail is reached from
  2 (interrupted) to 1 (failed). (2845 <https://github.com/pytest-dev/pytest/issues/2845>_)

• Fix issue in assertion rewriting which could lead it to rewrite modules which
  should not be rewritten. (2939 <https://github.com/pytest-dev/pytest/issues/2939>_)

• Handle marks without description in pytest.ini. (2942 <https://github.com/pytest-dev/pytest/issues/2942>_)

Trivial/Internal Changes

• pytest now depends on attrs <https://pypi.org/project/attrs/>_ for internal
  structures to ease code maintainability. (2641 <https://github.com/pytest-dev/pytest/issues/2641>_)

• Refactored internal Python 2/3 compatibility code to use six. (2642 <https://github.com/pytest-dev/pytest/issues/2642>_)

• Stop vendoring pluggy - we're missing out on its latest changes for not
  much benefit (2719 <https://github.com/pytest-dev/pytest/issues/2719>_)

• Internal refactor: simplify ascii string escaping by using the
  backslashreplace error handler in newer Python 3 versions. (2734 <https://github.com/pytest-dev/pytest/issues/2734>_)

• Remove unnecessary mark evaluator in unittest plugin (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• Calls to Metafunc.addcall now emit a deprecation warning. This function
  is scheduled to be removed in pytest-4.0. (2876 <https://github.com/pytest-dev/pytest/issues/2876>_)

• Internal move of the parameterset extraction to a more maintainable place.
  (2877 <https://github.com/pytest-dev/pytest/issues/2877>_)

• Internal refactoring to simplify scope node lookup. (2910 <https://github.com/pytest-dev/pytest/issues/2910>_)

• Configure pytest to prevent pip from installing pytest in unsupported
  Python versions. (2922 <https://github.com/pytest-dev/pytest/issues/2922>_)

3.2.5

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

Bug Fixes

• Remove py<1.5 restriction from pytest as this can cause version
  conflicts in some installations. (2926 <https://github.com/pytest-dev/pytest/issues/2926>_)

3.2.4

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

Bug Fixes

• Fix the bug where running with --pyargs will result in items with
  empty parent.nodeid if run from a different root directory. (2775 <https://github.com/pytest-dev/pytest/issues/2775>_)

• Fix issue with pytest.parametrize if argnames was specified as keyword arguments.
  (2819 <https://github.com/pytest-dev/pytest/issues/2819>_)

• Strip whitespace from marker names when reading them from INI config. (2856 <https://github.com/pytest-dev/pytest/issues/2856>_)

• Show full context of doctest source in the pytest output, if the line number of
  failed example in the docstring is < 9. (2882 <https://github.com/pytest-dev/pytest/issues/2882>_)

• Match fixture paths against actual path segments in order to avoid matching folders which share a prefix.
  (2836 <https://github.com/pytest-dev/pytest/issues/2836>_)

Improved Documentation

• Introduce a dedicated section about conftest.py. (1505 <https://github.com/pytest-dev/pytest/issues/1505>_)

• Explicitly mention xpass in the documentation of xfail. (1997 <https://github.com/pytest-dev/pytest/issues/1997>_)

• Clarify language of proposal for fixtures parameters (2893 <https://github.com/pytest-dev/pytest/issues/2893>_)

• List python 3.6 in the documented supported versions in the getting started
  document. (2903 <https://github.com/pytest-dev/pytest/issues/2903>_)

Django 1.11.6 -> 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,

  :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.

• 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
