Django 6.0 release notes - UNDER DEVELOPMENT
============================================

*Expected December 2025*

Welcome to Django 6.0!

These release notes cover the :ref:`new features <whats-new-6.0>`, as well as
some :ref:`backwards incompatible changes <backwards-incompatible-6.0>` you'll
want to be aware of when upgrading from Django 5.2 or earlier. We've
:ref:`begun the deprecation process for some features
<deprecated-features-6.0>`.

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

Python compatibility
====================

Django 6.0 supports Python 3.12 and 3.13. We **highly recommend** and only
officially support the latest release of each series.

The Django 5.2.x series is the last to support Python 3.10 and 3.11.

Third-party library support for older version of Django
=======================================================

Following the release of Django 6.0, we suggest that third-party app authors
drop support for all versions of Django prior to 5.2. 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 6.0.

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

Dropped support for Python < 3.12
---------------------------------

Because Python 3.12 is now the minimum supported version for Django, any
optional dependencies must also meet that requirement. The following versions
of each library are the first to add or confirm compatibility with Python 3.12:

* ``aiosmtpd`` 1.4.5
* ``argon2-cffi`` 23.1.0
* ``bcrypt`` 4.1.1
* ``geoip2`` 4.8.0
* ``Pillow`` 10.1.0
* ``mysqlclient`` 2.2.1
* ``numpy`` 1.26.0
* ``PyYAML`` 6.0.2
* ``psycopg`` 3.1.12
* ``psycopg2`` 2.9.9
* ``redis-py`` 5.1.0
