============================================ Django 6.0 release notes - UNDER DEVELOPMENT ============================================ *Expected December 2025* Welcome to Django 6.0! These release notes cover the :ref:`new features `, as well as some :ref:`backwards incompatible changes ` 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 `. 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 ======================== Minor features -------------- :mod:`django.contrib.admin` ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.admindocs` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * The new :attr:`.AdminSite.password_change_form` attribute allows customizing the form used in the admin site password change view. :mod:`django.contrib.auth` ~~~~~~~~~~~~~~~~~~~~~~~~~~ * The default iteration count for the PBKDF2 password hasher is increased from 1,000,000 to 1,200,000. :mod:`django.contrib.contenttypes` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.gis` ~~~~~~~~~~~~~~~~~~~~~~~~~ * The new :attr:`.GEOSGeometry.hasm` property checks whether the geometry has the M dimension. * The new :class:`~django.contrib.gis.db.models.functions.Rotate` database function rotates a geometry by a specified angle around the origin or a specified point. :mod:`django.contrib.messages` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.postgres` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.redirects` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.sessions` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.sitemaps` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.sites` ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.staticfiles` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.syndication` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ...

This aggregate was previously supported only for PostgreSQL. * The :meth:`~django.db.models.Model.save` method now raises a specialized :exc:`Model.NotUpdated ` exception, when :ref:`a forced update ` results in no affected rows, instead of a generic :exc:`django.db.DatabaseError`.
