* Fixed a regression in Django 2.2.1 that caused a crash when migrating
permissions for proxy models with a multiple database setup if the
``default`` entry was empty (:ticket:`31021`).
* Fixed a data loss possibility in the
:meth:`~django.db.models.query.QuerySet.select_for_update()`. When using
``'self'`` in the ``of`` argument with :ref:`multi-table inheritance
<multi-table-inheritance>`, a parent model was locked instead of the
queryset's model (:ticket:`30953`).
