Django 5.0 release notes - UNDER DEVELOPMENT
|
|
|
|
|
============================================
|
|
|
|
|
|
|
|
|
|
*Expected December 2023*
|
|
|
|
|
|
|
|
|
|
Welcome to Django 5.0!
|
|
|
|
|
|
|
|
|
|
These release notes cover the :ref:`new features <whats-new-5.0>`, as well as
|
|
|
|
|
some :ref:`backwards incompatible changes <backwards-incompatible-5.0>` you'll
|
|
|
|
|
want to be aware of when upgrading from Django 4.2 or earlier. We've
|
|
|
|
|
:ref:`begun the deprecation process for some features
|
|
|
|
|
<deprecated-features-5.0>`.
|
|
|
|
|
|
|
|
|
|
See the :doc:`/howto/upgrade-version` guide if you're updating an existing
|
|
|
|
|
project.
|
|
|
|
|
|
|
|
|
|
Python compatibility
|
|
|
|
|
====================
|
|
|
|
|
|
|
|
|
|
Django 5.0 supports Python 3.10, 3.11, and 3.12. 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 5.0, we suggest that third-party app authors
|
|
|
|
|
drop support for all versions of Django prior to 4.2. At that time, you should
|
|
|
|
|
be able to run your package's tests using ``python -Wd`` so that deprecation
|
|
|
|
|
warnings appear. After making the deprecation warning fixes, your app should be
|
|
|
|
|
compatible with Django 5.0.
