  10. ========

  11. 

  12. * Fixed a bug in Django 3.1 where ``FileField`` instances with a callable

  13.   storage were not correctly deconstructed (:ticket:`31941`).

  14. 

  15. * Fixed a regression in Django 3.1 where the :attr:`.QuerySet.ordered`

  16.   attribute returned incorrectly ``True`` for ``GROUP BY`` queries (e.g.

  17.   ``.annotate().values()``) on models with ``Meta.ordering``. A model's

  18.   ``Meta.ordering`` doesn't affect such queries (:ticket:`31990`).

  19. 

  20. * Fixed a regression in Django 3.1 where a queryset would crash if it contained

  21.   an aggregation and a ``Q`` object annotation (:ticket:`32007`).

  22. 

  23. * Fixed a bug in Django 3.1 where a test database was not synced during

  24.   creation when using the :setting:`MIGRATE <TEST_MIGRATE>` test database

  25.   setting (:ticket:`32012`).

  26. 

  27. * Fixed a ``django.contrib.admin.EmptyFieldListFilter`` crash when using on a

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

  29. 

  30. * Fixed a regression in Django 3.1.1 where the admin changelist filter sidebar

  31.   would not scroll for a long list of available filters (:ticket:`31986`).
