# Django 2.2.6 版本发行说明

*2019 年 10 月 1 日*

Django 2.2.6 fixes several bugs in 2.2.5.

## 漏洞修复

- Fixed migrations crash on SQLite when altering a model containing partial
  indexes ([#30754](https://code.djangoproject.com/ticket/30754)).
- Fixed a regression in Django 2.2.4 that caused a crash when filtering with a
  `Subquery()` annotation of a queryset containing
  `django.contrib.postgres.fields.JSONField` or
  [`HStoreField`](/zh-hans/4.0/ref/contrib/postgres/fields/#django.contrib.postgres.fields.HStoreField) ([#30769](https://code.djangoproject.com/ticket/30769)).
