+- Re-implemented the API, added support for duration/current in seconds & shuffle+repeat
+  - made the original API "legacy" (still works the same)
+  - Now using the correct HTTP verb for all new endpoints
 - Implemented TIDAL's universal links. All links are now universal.
 - Custom `tidal://` protocol fixed - By [TheRockYT](https://github.com/TheRockYT)
 - Global media shortcuts removed since TIDAL includes them by default - By [TheRockYT]
