Django 3.1.7 release notes

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

*February 19, 2021*

Django 3.1.7 fixes a security issue and a bug in 3.1.6.

CVE-2021-23336: Web cache poisoning via ``django.utils.http.limited_parse_qsl()``

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

Django contains a copy of :func:`urllib.parse.parse_qsl` which was added to

backport some security fixes. A further security fix has been issued recently

such that ``parse_qsl()`` no longer allows using ``;`` as a query parameter

separator by default. Django now includes this fix. See :bpo:`42967` for

further details.

Bugfixes

========

* Fixed a regression in Django 3.1 that caused ``RuntimeError`` instead of

  connection errors when using only the ``'postgres'`` database

  (:ticket:`32403`).
