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.
.. _whats-new-6.0:
What's new in Django 6.0
========================
Content Security Policy support
-------------------------------
Built-in support for the :ref:`Content Security Policy (CSP) <security-csp>`
standard is now available, making it easier to protect web applications against
content injection attacks such as cross-site scripting (XSS). CSP allows
declaring trusted sources of content by giving browsers strict rules about
which scripts, styles, images, or other resources can be loaded.
CSP policies can now be enforced or monitored directly using built-in tools:
headers are added via the
:class:`~django.middleware.csp.ContentSecurityPolicyMiddleware`, nonces are
supported through the :func:`~django.template.context_processors.csp` context
processor, and policies are configured using the :setting:`SECURE_CSP` and
:setting:`SECURE_CSP_REPORT_ONLY` settings.
These settings accept Python dictionaries and support Django-provided constants
for clarity and safety. For example::
from django.utils.csp import CSP
SECURE_CSP = {
"default-src": [CSP.SELF],
"script-src": [CSP.SELF, CSP.NONCE],
"img-src": [CSP.SELF, "https:"],
}
The resulting ``Content-Security-Policy`` header would be set to:
.. code-block:: text
default-src 'self'; script-src 'self' 'nonce-SECRET'; img-src 'self' https:
To get started, follow the :doc:`CSP how-to guide </howto/csp>`. For in-depth
guidance, see the :ref:`CSP security overview <security-csp>` and the
:doc:`reference docs </ref/csp>`.

.. _backwards-incompatible-6.0:
Backwards incompatible changes in 6.0
=====================================
Database backend API
--------------------
This section describes changes that may be needed in third-party database
backends.
* ``BaseDatabaseCreation.create_test_db(serialize)`` is deprecated. Use
``serialize_db_to_string()`` instead.
* :class:`~django.db.backends.base.schema.BaseDatabaseSchemaEditor` and
PostgreSQL backends no longer use ``CASCADE`` when dropping a column.
Dropped support for MariaDB 10.5
--------------------------------
Upstream support for MariaDB 10.5 ends in June 2025. Django 6.0 supports
MariaDB 10.6 and higher.
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
* ``selenium`` 4.23.0
* ``sqlparse`` 0.5.0
* ``tblib`` 3.0.0
Miscellaneous
-------------
* The :ref:`JSON <serialization-formats-json>` serializer now writes a newline
at the end of the output, even without the ``indent`` option set.
* The undocumented ``django.utils.http.parse_header_parameters()`` function is
refactored to use Python's :py:class:`email.message.Message` for parsing.
Input headers exceeding 10000 characters will now raise :exc:`ValueError`.
* Widgets from :mod:`django.contrib.gis.forms.widgets` now render without
inline JavaScript in templates. If you have customized any geometry widgets
or their templates, you may need to :ref:`update them
<geometry-widgets-customization>` to match the new layout.
* Message levels ``messages.DEBUG`` and ``messages.INFO`` now have distinct
icons and CSS styling in the admin. Previously, these used the same icon and
styling as the ``messages.SUCCESS`` level. Since
:meth:`.ModelAdmin.message_user` uses the ``messages.INFO`` level by default,
set the level to ``messages.SUCCESS`` to retain the previous icon and
styling.
* The minimum supported version of ``asgiref`` is increased from 3.8.1 to
3.9.1.
.. _deprecated-features-6.0:
Features deprecated in 6.0
==========================
Miscellaneous
-------------
* ``BaseDatabaseCreation.create_test_db(serialize)`` is deprecated. Use
``serialize_db_to_string()`` instead.
* The PostgreSQL ``StringAgg`` class is deprecated in favor of the generally
available :class:`~django.db.models.StringAgg` class.
* The PostgreSQL ``OrderableAggMixin`` is deprecated in favor of the
``order_by`` attribute now available on the ``Aggregate`` class.
* The default protocol in :tfilter:`urlize` and :tfilter:`urlizetrunc` will
change from HTTP to HTTPS in Django 7.0. Set the transitional setting
``URLIZE_ASSUME_HTTPS`` to ``True`` to opt into assuming HTTPS during the
Django 6.x release cycle.
* ``URLIZE_ASSUME_HTTPS`` transitional setting is deprecated.
* Setting :setting:`ADMINS` or :setting:`MANAGERS` to a list of (name, address)
tuples is deprecated. Set to a list of email address strings instead. Django
never used the name portion. To include a name, format the address string as
``'"Name" <address>'`` or use Python's :func:`email.utils.formataddr`.
* Support for the ``orphans`` argument being larger than or equal to the
``per_page`` argument of :class:`django.core.paginator.Paginator` and
:class:`django.core.paginator.AsyncPaginator` is deprecated.
* Using a percent sign in a column alias or annotation is deprecated.
