==========================

3.1.2

==========================

*October 1, 2020*

Django 3.1.2 fixes several bugs in 3.1.1.

Bugfixes
========

* Fixed a bug in Django 3.1 where ``FileField`` instances with a callable
storage were not correctly deconstructed (:ticket:`31941`).

setting (:ticket:`32012`).

``GenericRelation`` (:ticket:`32038`).

* Fixed a regression in Django 3.1.1 where the admin changelist filter sidebar
would not scroll for a long list of available filters (:ticket:`31986`).
