Full changelog

Calendar – recurring event end time shifted by UTC offset: When expanding recurring events server-side, end_datetime for each instance was computed via .toISOString(), which always appends a Z (UTC) suffix. Stored datetimes use no timezone marker (naive local-time strings), so browsers interpreted the Z-suffixed recurring instances as UTC — shifting displayed end times by the user's UTC offset (e.g. +2 h for UTC+2). The fix preserves the format of the original datetime: naive sources produce a timezone-free YYYY-MM-DDTHH:MM string; Z-suffixed sources (e.g. CalDAV imports) retain the ISO/UTC path.
