In order to improve accessibility and enable screen readers to associate fieldsets with their help text, the form fieldset now includes the aria-describedby HTML attribute.

Models¶

QuerySet.explain() now supports the generic_plan option on PostgreSQL 16+.
RowRange now accepts positive integers for the start argument and negative integers for the end argument.
The new exclusion argument of RowRange and ValueRange allows excluding rows, groups, and ties from the window frames.

Templates¶

Custom tags may now set extra data on the Parser object that will later be made available on the Template instance. Such data may be used, for example, by the template loader, or other template clients.
The new {% query_string %} template tag allows changing a QueryDict instance for use in links, for example, to generate a link to the next page while keeping any filtering options in place.

Tests¶

assertContains(), assertNotContains(), and assertInHTML() assertions now add haystacks to assertion error messages.
The Django test runner now supports a --screenshots option to save screenshots for Selenium tests.
The RequestFactory, AsyncRequestFactory, Client, and AsyncClient classes now support the query_params parameter, which accepts a dictionary of query string keys and values. This allows setting query strings on any HTTP methods more easily.
```
self.client.post("/items/1", query_params={"action": "delete"})
await self.async_client.post("/items/1", query_params={"action": "delete"})
```

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.

Features deprecated in 5.1¶

Miscellaneous¶

The ModelAdmin.log_deletion() and LogEntryManager.log_action() methods are deprecated. Subclasses should implement ModelAdmin.log_deletions() and LogEntryManager.log_actions() instead.
