# Django 2.1.12 リリースノート

Django 2.1.12 fixes a regression in 2.1.11.

## バグ修正

- Fixed crash of `KeyTransform()` for
  `django.contrib.postgres.fields.JSONField` and
  [`HStoreField`](/ja/6.1/ref/contrib/postgres/fields/#django.contrib.postgres.fields.HStoreField) when using on
  expressions with params ([#30672](https://code.djangoproject.com/ticket/30672)).
