===========================
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`).
