============================================
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.
The Django 4.2.x series is the last to support Python 3.8 and 3.9.
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.
