+
+# v0.15.1 (2023-12-26)
+
+* Updated Telegram API to layer 169.
+* Updated Docker image to Alpine 3.19.
+* Fixed some potential cases where a portal room would be created for the
+  relaybot even if `ignore_unbridged_group_chat` was enabled.
+* Fixed member sync in groups with hidden members causing puppeted Matrix users
+  to be kicked even if they're still in the group.
+
+# v0.15.0 (2023-11-26)
+
+* Removed support for MSC2716 backfilling.
+* Added `add-contact` and `delete-contact` commands.
+* Updated Telegram API layer to 166.
+  * Includes receiving view-once media, blockquotes, quote replies and other
+    such things
+* Fixed AuthKeyNotFound errors not being handled and causing users to get stuck
+  in a non-logged-in state.
+
+# v0.14.2 (2023-09-19)
+
+* **Security:** Updated Pillow to 10.0.1.
+* Added support for double puppeting with arbitrary `as_token`s.
+  See [docs](https://docs.mau.fi/bridges/general/double-puppeting.html#appservice-method-new) for more info.
+* Added support for sending webm and tgs files as stickers.
+* Updated to Telegram API layer 161.
+* Fixed cached usernames for Telegram users being cleared incorrectly, leading
+  to mentions not being bridged as usernames.
+* Fixed reaction bridging failing if the server running the bridge was rebooted
+  less than 12 hours ago.
+
+# v0.14.1 (2023-06-26)
+
+### Added
+* Added option to delete megolm sessions that were received before the
+  automatic ratcheting options were introduced.
+* Added config option to use IPv6 for Telegram connection
+  (thanks to [@exciler] in [#920]).
+
+### Improved
+* Dropped support for Python 3.8.
+* Updated Docker image to Alpine 3.18.
+* Added timeout for forward backfills to prevent it from getting stuck
+  permanently.
+
+### Fixed
+* Fixed `bridge.filter.users` config option not being read correctly.
+* Fixed proxy support to use python-socks instead of pysocks.

+[@exciler]: https://github.com/exciler
+[#920]: https://github.com/mautrix/telegram/pull/920
+
+# 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]).
