# Django 4.0.5 release notes

*June 1, 2022*

Django 4.0.5 fixes several bugs in 4.0.4.

## Bugfixes

- Fixed a bug in Django 4.0 where not all [`OPTIONS`](/ja/4.1/ref/settings/#std-setting-CACHES-OPTIONS)
  were passed to a Redis client ([#33681](https://code.djangoproject.com/ticket/33681)).
- Fixed a bug in Django 4.0 that caused a crash of `QuerySet.filter()` on
  `IsNull()` expressions ([#33705](https://code.djangoproject.com/ticket/33705)).
- Fixed a bug in Django 4.0 where a hidden quick filter toolbar in the admin's
  navigation sidebar was focusable ([#33725](https://code.djangoproject.com/ticket/33725)).
