 ## [Unreleased]
 
-### Fixed
-- **A deleted occurrence no longer comes back when the series is re-timed.**
-  Delete a single occurrence of a repeating event, then change the time of the
-  whole series, and the occurrence you had removed reappeared. Doing it the
-  other way round — "This and all following events" — lost every removal in the
-  part of the series being changed. Removals now travel with the event: they
-  keep their place in the series across a time change, a move to a different
-  day, a timezone change and a switch to or from an all-day event, and they
-  carry over when a series is split. Repeating events on your device's own
-  calendars are affected, including the birthday and anniversary calendars
-  Calendula creates from your contacts ([#248]).
