Django 5.0.4 release notes
==========================
*April 3, 2024*
Django 5.0.4 fixes several bugs in 5.0.3.
Bugfixes
========
* Fixed a bug in Django 5.0 that caused a crash of ``Model.full_clean()`` on
fields with expressions in ``db_default``. As a consequence,
``Model.full_clean()`` no longer validates for empty values in fields with
``db_default`` (:ticket:`35223`).
* Fixed a regression in Django 5.0 where the ``AdminFileWidget`` could be
rendered with two ``id`` attributes on the "Clear" checkbox
(:ticket:`35273`).
* Fixed a bug in Django 5.0 that caused a migration crash on PostgreSQL 15+
when adding a partial ``UniqueConstraint`` with ``nulls_distinct``
(:ticket:`35329`).
* Fixed a crash in Django 5.0 when performing queries involving table aliases
and lookups on a ``GeneratedField`` of the aliased table (:ticket:`35344`).
* Fixed a bug in Django 5.0 that caused a migration crash when adding a
``GeneratedField`` relying on the ``__contains`` or ``__icontains``
lookups or using a ``Value`` containing a ``"%"`` (:ticket:`35336`).
