# khal v0.9.1 released

This is a bug fix release for python 3.6.

Under python 3.6, datetimes with timezone information that is missing from the icalendar file would be treated if they were in the system’s local timezone, not as if they were in khal’s configured default timezone. This could therefore lead to erroneous offsets in start and end times for those events.

To check if you are affected by this bug, delete khal’s database file (usually `~/.local/share/khal/khal.db`), rerun khal and watch for error messages that look like the one below:

> warning: DTSTART localized in invalid or incomprehensible timezone FOO in events/event_dt_local_missing_tz.ics. This could lead to this event being wrongly displayed.

All users (of python 3.6) are advised to upgrade as soon as possible.

Get khal v0.9.1 from this site, or from pypi.
