* Fixed a data loss possibility in the admin changelist view when a custom
:ref:`formset's prefix <formset-prefix>` contains regular expression special
characters, e.g. `'$'` (:ticket:`31031`).
* 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
