Django 2.2.16 release notes
===========================

*Expected September 1, 2020*

Django 2.2.16 fixes two data loss bugs in 2.2.15.

Bugfixes
========

* Fixed a data loss possibility in the
  :meth:`~django.db.models.query.QuerySet.select_for_update()`. When using
  related fields pointing to a proxy model in the ``of`` argument, the
  corresponding model was not locked (:ticket:`31866`).

* Fixed a data loss possibility, following a regression in Django 2.0, when
  copying model instances with a cached fields value (:ticket:`31863`).
