We’re happy to announce the release of Django MongoDB Backend 5.2.4, a bug fix and performance release for the 5.2.x LTS series, which supports Django 5.2 LTS.

Bug fixes

  • Prevented django_mongodb_backend.transaction.atomic() from silencing exceptions raised on commit.
  • Fixed a crash when saving a model with PolymorphicEmbeddedModelField or PolymorphicEmbeddedModelArrayField that specifies embedded_models as a list of concrete models.

Performance improvements

  • Improved QuerySet join ($lookup) performance by pushing complex conditions from the WHERE ($match) clause to the $lookup stage.

See the full release notes for details: django-mongodb-backend/docs/releases/5.2.x.rst at main · mongodb/django-mongodb-backend · GitHub

Install or upgrade with pip install --upgrade django-mongodb-backend==5.2.4.
