# Django 4.2.2 release notes

*June 5, 2023*

Django 4.2.2 fixes several bugs in 4.2.1.

## Poprawki błędów

- Fixed a regression in Django 4.2 that caused an unnecessary
  `DBMS_LOB.SUBSTR()` wrapping in the `__isnull` and `__exact=None`
  lookups for `TextField()`/`BinaryField()` on Oracle ([#34544](https://code.djangoproject.com/ticket/34544)).
- Restored, following a regression in Django 4.2, `get_prep_value()` call in
  `JSONField` subclasses ([#34539](https://code.djangoproject.com/ticket/34539)).
- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.defer()`
  when passing a `ManyToManyField` or `GenericForeignKey` reference. While
  doing so is a no-op, it was allowed in older version ([#34570](https://code.djangoproject.com/ticket/34570)).
- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.only()`
  when passing a reverse `OneToOneField` reference ([#34612](https://code.djangoproject.com/ticket/34612)).
- Fixed a bug in Django 4.2 where [`makemigrations --update`](/pl/6.0/ref/django-admin/#cmdoption-makemigrations-update) didn’t
  respect the `--name` option ([#34568](https://code.djangoproject.com/ticket/34568)).
- Fixed a performance regression in Django 4.2 when compiling queries without
  ordering ([#34580](https://code.djangoproject.com/ticket/34580)).
- Fixed a regression in Django 4.2 where nonexistent stylesheet was linked on a
  “Congratulations!” page ([#34588](https://code.djangoproject.com/ticket/34588)).
- Fixed a regression in Django 4.2 that caused a crash of
  `QuerySet.aggregate()` with expressions referencing other aggregates
  ([#34551](https://code.djangoproject.com/ticket/34551)).
- Fixed a regression in Django 4.2 that caused a crash of
  `QuerySet.aggregate()` with aggregates referencing subqueries
  ([#34551](https://code.djangoproject.com/ticket/34551)).
- Fixed a regression in Django 4.2 that caused a crash of querysets on SQLite
  when filtering on `DecimalField` against values outside of the defined
  range ([#34590](https://code.djangoproject.com/ticket/34590)).
- Fixed a regression in Django 4.2 that caused a serialization crash on a
  `ManyToManyField` without a natural key when its `Manager`’s base
  `QuerySet` used `select_related()` ([#34620](https://code.djangoproject.com/ticket/34620)).
