Django 5.1 release notes - UNDER DEVELOPMENT

Expected August 2024

Welcome to Django 5.1!

These release notes cover the new features, as well as some backwards incompatible changes you’ll want to be aware of when upgrading from Django 5.0 or earlier. We’ve begun the deprecation process for some features.

See the How to upgrade Django to a newer version guide if you’re updating an existing project.

Python compatibility

Django 5.1 supports Python 3.10, 3.11, and 3.12. We highly recommend and only officially support the latest release of each series.

Backwards incompatible changes in 5.1

Database backend API

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

django.contrib.gis

  • Support for PostGIS 2.5 is removed.

Dropped support for MariaDB 10.4

Upstream support for MariaDB 10.4 ends in June 2024. Django 5.1 supports MariaDB 10.5 and higher.

Dropped support for PostgreSQL 12

Upstream support for PostgreSQL 12 ends in November 2024. Django 5.1 supports PostgreSQL 13 and higher.

Miscellaneous

  • In order to improve accessibility, the admin’s changelist filter is now rendered in a <nav> tag instead of a <div>.
  • SimpleTestCase.assertURLEqual() and assertInHTML() now add ": " to the msg_prefix. This is consistent with the behavior of other assertions.
