Django 3.0.1 release notes
==========================
*Expected January 2, 2020*
Django 3.0.1 fixes several bugs in 3.0.
Bugfixes
========
* Fixed a regression in Django 3.0 by restoring the ability to use Django
inside Jupyter and other environments that force an async context, by adding
and option to disable :ref:`async-safety` mechanism with
``DJANGO_ALLOW_ASYNC_UNSAFE`` environment variable (:ticket:`31056`).
* Fixed a regression in Django 3.0 where ``RegexPattern``, used by
:func:`~django.urls.re_path`, returned positional arguments to be passed to
the view when all optional named groups were missing (:ticket:`31061`).
* Reallowed, following a regression in Django 3.0,
:class:`~django.db.models.expressions.Window` expressions to be used in
conditions outside of queryset filters, e.g. in
:class:`~django.db.models.expressions.When` conditions (:ticket:`31060`).
