+### Added
+- Settings → Calendars now says what is different about a calendar instead of
+  leaving you to guess. Ones you can only view — a subscribed calendar, a
+  calendar shared with you read-only — are marked **Read-only** ([#76]).
+- Calendars your device isn't syncing are marked **Not synced**, moved to the
+  bottom of their account and left without a switch. None of their events are on
+  the device, so the switch they used to have could not have shown you anything
+  — the calendar simply looked broken. They are no longer offered when you pick
+  a calendar for a new or an imported event either: an event saved there would
+  never reach the account. Whether an account syncs a calendar stays that
+  account's own app's decision ([#78]).
+- The birthday and anniversary calendars Calendula fills from your contacts are
+  marked **Filled from your contacts**, which is why they can't be picked for a
+  new event: anything you put there would be removed again on the next sync.
+  Deleting one is held back while special dates are switched on — Calendula
+  would simply create it again — and the calendar's editor says so; turn the
+  feature off under Settings → Special dates and the delete works as usual
+  ([#76]).
+- The calendar picker in the event form and in the .ics import screen now ends
+  with a **"Missing a calendar?"** row that opens Settings → Calendars, where
+  those marks then explain why a calendar isn't offered ([#76]).
+
+### Changed
+- Calendula's source code now lives on **Codeberg**, where its issues already
+  were. The **Source code** and **License** links in Settings → About point
+  there, so reporting a bug and reading the code no longer land on two different
+  sites. Nothing about the app itself changes, and the F-Droid repository is
+  unaffected.

 ### Fixed
 - Search results now show an all-day event's real date. West of UTC — anywhere in
   the Americas, say — a search hit was dated one day early, disagreeing with the
