-* Fixed bridging long text messages from Signal
-  (thanks to [@maltee1] in [#506]).
-* Improved handling of ping timeouts in Signal websocket.

-    room will not have a ghost user for the recipient until they accept the
-    message request.
-* Added support for syncing existing groups on login instead of having to wait
-  for new messages.
-* Added notices if decrypting incoming message from Signal fails.
-* Added bridging of group metadata from Matrix to Signal

-  (thanks to [@maltee1] in [#495]).
-* Improved handling of missed Signal group metadata changes

+  * All users will have to re-link the bridge.
-    migrated (e.g. log config). If you prevented the bridge from writing to
+  * Primary device mode is no longer supported.
-    the config file, you'll have to temporarily allow it or update it yourself.
-  * The bridge doesn't use signald anymore, all users will have to re-link the
-    bridge. signald can be deleted after upgrading.
-  * Primary device mode is no longer supported, signal-cli is recommended if
-    you don't want to use the official Signal mobile apps.
-  * Some old features are not yet supported (e.g. group management features).
 * Renamed main branch from `master` to `main`.
-* Added support for edits and message formatting.
