v1.44.1

Fixed

• Recurring weekday calendar events (for example a Monday to Friday school schedule) synced from CalDAV or an ICS subscription no longer disappear when the series contains individually edited occurrences. Such a modified occurrence (iCalendar RECURRENCE-ID) previously overwrote the whole series and collapsed it into a single stray event on an unexpected date; modified occurrences are now kept as their own entries, the original time slot is suppressed, and excluded dates (EXDATE, for example public holidays) are now honored on CalDAV calendars too. Affected calendars repair themselves on the next sync (#549).
