+# 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]).
+
+[@Steffo99]: https://github.com/Steffo99

+[#892]: https://github.com/mautrix/telegram/pull/892
+[#902]: https://github.com/mautrix/telegram/pull/902
+
+# v0.13.0 (2023-02-26)
+
+### Added
+* Added `allow_contact_info` config option to specify whether personal names
+  and avatars for other users should be bridged.
+  * The option is only safe to enable on single-user instances, using it
+    anywhere else will cause ghost user profiles to flip back and forth between
+    personal and default ones.
+* Added config option to notify Matrix room if bridging an incoming message
+  fails.
+
+### Improved
+* Updated Docker image to Alpine 3.17.
+* Updated to Telegram API layer 152.
+* Improved handling users getting logged out.
+* Removed support for creating accounts, as Telegram only allows requesting SMS
+  login codes on the official mobile clients now.
+* Replaced moviepy with calling ffmpeg directly for generating video thumbnails.
+
+### Fixed
+* Fixed handling Telegram chat upgrades when backfilling is enabled.
+* Fixed file transfers failing if transfering the thumbnail fails.
+* Fixed bridging unnamed files with unrecognized mime types.
+* Fixed enqueueing more backfill.
+* Fixed timestamps not being saved in `telegram_file` table.
+* Fixed issues with old events being replayed if the bridge was shut down
+  uncleanly.
