Problem and impact

Log entry shows:

/usr/local/lib/python3.11/site-packages/vobject/icalendar.py:341: PytzUsageWarning: The zone attribute is specific to pytz's interface; please migrate to a new time zone provider. For more details on how to do so, see https://pytz-deprecation-shim.readthedocs.io/en/latest/migration.html

  return toUnicode(tzinfo.zone)
/usr/local/lib/python3.11/site-packages/vobject/icalendar.py:1744: PytzUsageWarning: The localize method is no longer necessary, as this time zone supports the fold attribute (PEP 495).

return tzinfo.localize(datetime.datetime(year, month, day, hour, minute, second))

There are 3 issues with this file, it does not look like eventable/vobject is maintained any more

Expected behaviour

Unsure, either the project needs a fork to atleast migrate the Pytz changes, or Pretix needs a replacement for this library.
