============================================ Django 6.2 release notes - UNDER DEVELOPMENT ============================================ *Expected April 2027* Welcome to Django 6.2! These release notes cover the :ref:`new features `, as well as some :ref:`backwards incompatible changes ` you should be aware of when upgrading from Django 6.1 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. Django 6.2 is designated as a :term:`long-term support release `. It will receive security updates for at least three years after its release. Support for the previous LTS, Django 5.2, will end in April 2028. Python compatibility ==================== Django 6.2 supports Python 3.12, 3.13 and 3.14. We **highly recommend** and only officially support the latest release of each series. .. _whats-new-6.2: What's new in Django 6.2 ======================== Minor features -------------- :mod:`django.contrib.admin` ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.admindocs` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.auth` ~~~~~~~~~~~~~~~~~~~~~~~~~~ * The default iteration count for the PBKDF2 password hasher is increased from 1,500,000 to 1,800,000. :mod:`django.contrib.contenttypes` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :mod:`django.contrib.gis` ~~~~~~~~~~~~~~~~~~~~~~~~~ * ... :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` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * ...

Management Commands ~~~~~~~~~~~~~~~~~~~ * The new :djadmin:`listurls` command lists the URLs from the project's root URLconf, including the view class or function (and name, if present). * The :djadmin:`makemigrations` command now tracks all changes to unmanaged models, including field additions, removals, alterations, constraints, and model renames. After upgrading, you will see new migrations detected for unmanaged models that have changed since their creation. * Whether to suppress an :exc:`ImportError` escaping from a settings module is configurable by the new :attr:`.BaseCommand.requires_settings` attribute (default ``True``). In previous versions, such errors were always suppressed. Migrations ~~~~~~~~~~ * ... Models ~~~~~~ * ... Requests and Responses ~~~~~~~~~~~~~~~~~~~~~~ * ... Security ~~~~~~~~ * ... Serialization ~~~~~~~~~~~~~ * ... Signals ~~~~~~~ * ... Tasks ~~~~~ * ... Templates ~~~~~~~~~ * ... Tests ~~~~~ * :meth:`~django.test.Client.force_login` now skips members of :setting:`AUTHENTICATION_BACKENDS` not implementing ``(a)get_user()``, e.g. permission-only backends. URLs ~~~~ * ... Utilities ~~~~~~~~~ * :func:`.utils.module_loading.import_string` now supports modules. Previously, top-level modules did not work, and submodules only worked if already imported. * ... Validators ~~~~~~~~~~ * ... .. _backwards-incompatible-6.2: Backwards incompatible changes in 6.2 ===================================== Database backend API -------------------- This section describes changes that may be needed in third-party database backends. * ... Miscellaneous ------------- * To facilitate the deprecation of the ``safe`` parameter of :class:`~django.http.JsonResponse`, it now defaults to ``False``, because the pollution vulnerability in the ``Array`` prototype was fixed in `ES5 `_. * :class:`~django.core.serializers.json.DjangoJSONEncoder` now omits the millisecond component of serialized ``datetime.datetime`` and ``datetime.time`` objects if they have zero milliseconds. For example, ``datetime.datetime(2000, 1, 1, 0, 0, 0, 1)`` now serializes to ``"2000-01-01T00:00:00"`` rather than ``"2000-01-01T00:00:00.000"``. * :func:`.utils.module_loading.import_string` now deterministically favors submodules in ambiguous cases where depending on prior import state, a same-named attribute of the parent module might have been returned instead. * The minimum supported version of ``asgiref`` is increased from 3.9.1 to 3.12.1. .. _deprecated-features-6.2: Features deprecated in 6.2 ========================== Miscellaneous ------------- * The :class:`~django.middleware.MiddlewareMixin` class moved from ``django.utils.deprecation`` to ``django.middleware``. The old import path is deprecated. * The ``safe`` parameter is deprecated from :class:`~django.http.JsonResponse`. Omitting the argument is equivalent to the prior ``safe=False`` usage. * Calling :meth:`.QuerySet.aiterator` after ``prefetch_related()`` without providing a ``chunk_size`` is deprecated. It currently falls back to a ``chunk_size`` of 2000, but a ``ValueError`` will be raised in Django 7.1.
