# Django REST framework 3.15

At the Internet, on March 15th, 2024, with 176 commits by 138 authors, we are happy to announce the release of Django REST framework 3.15.

## Django 5.0 and Python 3.12 support

The latest release now fully supports Django 5.0 and Python 3.12.

The current minimum versions of Django still is 3.0 and Python 3.6.

## Primary Support of UniqueConstraint

`ModelSerializer` generates validators for [UniqueConstraint](https://docs.djangoproject.com/en/4.0/ref/models/constraints/#uniqueconstraint) (both UniqueValidator and UniqueTogetherValidator)

## ValidationErrors improvements

The `ValidationError` has been aligned with Django's, currently supporting the same style (signature) and nesting.

## SimpleRouter non-regex matching support

By default the URLs created by `SimpleRouter` use regular expressions. This behavior can be modified by setting the `use_regex_path` argument to `False` when instantiating the router.

## ZoneInfo as the primary source of timezone data

Dependency on pytz has been removed and deprecation warnings have been added, Django will provide ZoneInfo instances as long as USE_DEPRECATED_PYTZ is not enabled. More info on the migration can be found [in this guide](https://pytz-deprecation-shim.readthedocs.io/en/latest/migration.html).

##  Align `SearchFilter` behaviour to `django.contrib.admin` search

Searches now may contain _quoted phrases_ with spaces, each phrase is considered as a single search term, and it will raise a validation error if any null-character is provided in search. See the [Filtering API guide](../api-guide/filtering.md) for more information.

## Default values propagation

Model fields' default values are now propagated to serializer fields, for more information see the [Serializer fields API guide](../api-guide/fields.md#default).

## Other fixes and improvements

There are a number of fixes and minor improvements in this release, ranging from documentation, internal infrastructure (typing, testing, requirements, deprecation, etc.), security and overall behaviour.

See the [release notes](release-notes.md) page for a complete listing.
