``pytz`` is a required dependency and support for ``settings.TIME_ZONE = None`` is removed
------------------------------------------------------------------------------------------
To simplify Django's timezone handling, ``pytz`` is now a required dependency.
It's automatically installed along with Django.
Support for ``settings.TIME_ZONE = None`` is removed as the behavior isn't
commonly used and is questionably useful. If you want to automatically detect
the timezone based on the system timezone, you can use `tzlocal
<https://pypi.python.org/pypi/tzlocal>`_::
from tzlocal import get_localzone
TIME_ZONE = get_localzone().zone
This works similar to ``settings.TIME_ZONE = None`` except that it also sets
``os.environ['TZ']``. `Let us know

if there's a use case where you find you can't adapt your code to set a
``TIME_ZONE``.
