+# v0.14.0 (2023-05-26)
+
+### Added
+* Added fallback messages for calls and premium gifts.
+* Added options to automatically ratchet/delete megolm sessions to minimize
+  access to old messages.
+* Added option to not set room name/avatar even in encrypted rooms.
+* Implemented appservice pinging using MSC2659.
+* Added option to disable or filter bridging direct chats
+  (thanks to [@Steffo99] in [#892]).
+* Added options to specify different limits for forward and catchup backfilling
+  depending on chat type.
+
+### Improved
+* Improved handling logouts and certain connection errors.
+* Changed reaction bridging to preserve timestamps.
+* Disabled creating portals for DMs that don't have any messages when
+  `sync_direct_chats` is enabled.
+
+### Fixed
+* Fixed syncing mute status when portal is created through incoming message
+  rather than in startup sync.
+* Fixed bridge incorrectly trusting member list and kicking users when
+  supergroup has member list hidden.
+* Fixed sending messages after creating groups from Matrix using relaybot
+  instead of puppet (thanks to [@maltee1] in [#902]).
