    Version 3.4.0

    Works with firefox 109.0a1 and later
    What's new in 3.4.0

    • Google Calendar sync now works both ways automatically: after the first sync, changes made in DayMark and in Google Calendar keep each other up to date.
    • The first sync is much faster and shows its progress ("Syncing… n of total").
    • Choosing a calendar is clearer: the chosen calendar stays chosen, and the Google dialog shows whether its first sync is finished. An interrupted sync continues where it stopped.
    • Editing an event in DayMark no longer removes a meeting's place, notes, guests or reminders in Google Calendar.
    • Events made in Google Calendar without a colour no longer fall into one of your categories, and their titles are kept whole.
    • The popup is exactly as tall as the calendar, with no empty strip, and it no longer flickers when it opens.
    • Many smaller fixes and improvements.
