------------------------------------------+------------------------
Python 3.9 introduced `zoneinfo` timezone objects, with backports
available to Python 3.6.
As [https://groups.google.com/g/django-developers/c/PtIyadoC-fI per
discussion on mailing list] we will adopt `zoneinfo` in Django 4.0, using
a `pytz` compatibility shim for those who need it until Django 5.0.
In addition, as per [https://groups.google.com/g/django-
developers/c/cXIyCcjMOds/m/L1H2hlHpCgAJ follow-up discussion], we will
make it possible to use `zoneinfo` objects from Django 3.2, leaving any
handling of DST changes to early-adopter user code. (`make_aware()`'s
`is_dst` likely to be deprecated in Django 4.0 — see follow-up discussion
and [https://github.com/django/django/pull/13877#issuecomment-758769902
comment on initial PR].)
