Django 2.0 release notes - UNDER DEVELOPMENT
|
|
============================================
|
|
|
|
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>`.
|
|
|
|
See the :doc:`/howto/upgrade-version` guide if you're updating an existing
|
|
project.
|
|
|
|
Python compatibility
|
|
====================
|
|
|
|
Django 2.0 supports Python 3.5+. Since Django 1.11, support for Python 2.7 and
|
|
3.4 is removed. We **highly recommend** and only officially support the latest
|
|
release of each series.
|
|
|
|
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 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.

|
These features have reached the end of their deprecation cycle and are removed
|
|
in Django 2.0. See :ref:`deprecated-features-1.9` and
|
|
:ref:`deprecated-features-1.10` for details, 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 ``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.

|
required.
|
|
|
|
* ``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.

|
|
* ``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
|
|
