 Mostly based on [keepachangelog](https://keepachangelog.com/en/1.0.0/) except date format. a-c-f-r-o
 
+## [5.1.11] - 03.10.2024
+
+### Added
+
+- Added `%user.displayname%` placeholder. It will show users nickname, if there is one, otherwise it will show the username.
+  - Nickname won't be shown in bye messages.
+- Added initial version of grpc api. Beta
+ 
+### Fixed
+
+- Fixed a bug which caused `.bye` and `.greet` messages to be randomly disabled
+- Fixed `.lb -c` breaking sometimes, and fixed pagination
+
+### Changed
+
+- Youtube now always uses `yt-dlp`. Dropped support for `youtube-dl`
+  - If you've previously renamed your yt-dlp file to youtube-dl, please rename it back.
+- ytProvider in data/searches.yml now also controls where you're getting your song streams from.
+  - (Invidious support added for .q)
+
+## [5.1.10] - 24.09.2024
+
+### Fixed
+
+- Fixed claimed waifu decay in `games.yml`
+
+### Changed
+
+- Added some logs for greet service in case there are unforeseen issues, for easier debugging
+
+## [5.1.9] - 21.09.2024
+
+### Fixed
+
+- Fixed `.greettest`, and other `.*test` commands if you didn't have them enabled.
+- Fixed `.greetdmtest` sending messages twice.
+- Fixed a serious bug which caused greet messages to be jumbled up, and wrong ones to be sent for the wrong events.
+  - There is no database issue, all greet messages are safe, the cache was caching any setting every 3 seconds with no regard for the type of the event
+  - This also caused `.greetdm` messages to not be sent if `.greet` is enabled
+  - This bug was introduced in 5.1.8. PLEASE UPDATE if you are on 5.1.8 
+- Selfhosters only: Fixed medusa dependency loading
+  -  Note: Make sure to not publish any other DLLs besides the ones you are sure you will need, as there can be version conflicts which didn't happen before.
+
 ## [5.1.8] - 19.09.2024
