# Django 2.1.3 release notes

*2018年11月1日*

Django 2.1.3 fixes several bugs in 2.1.2.

## Bugfixes

- Fixed a regression in Django 2.0 where combining `Q` objects with `__in`
  lookups and lists crashed ([#29838](https://code.djangoproject.com/ticket/29838)).
- Fixed a regression in Django 1.11 where `django-admin shell` may hang
  on startup ([#29774](https://code.djangoproject.com/ticket/29774)).
- Fixed a regression in Django 2.0 where test databases aren't reused with
  `manage.py test --keepdb` on MySQL ([#29827](https://code.djangoproject.com/ticket/29827)).
- Fixed a regression where cached foreign keys that use `to_field` were
  incorrectly cleared in `Model.save()` ([#29896](https://code.djangoproject.com/ticket/29896)).
- Django 2.0 で、並列での保存時に同じディレクトリを作成しようとした場合に、`FileSystemStorage` が `FileExistsError` 例外を起こしてクラッシュするリグレッションを修正しました ([#29890](https://code.djangoproject.com/ticket/29890))。
