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 (#35223).

• Fixed a bug in Django 5.0 that caused a migration crash on PostgreSQL 15+ when adding a partial UniqueConstraint with nulls_distinct (#35329).
• Fixed a crash in Django 5.0 when performing queries involving table aliases and lookups on a GeneratedField of the aliased table (#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 "%" (#35336).
