Available since almost two weeks:

"New in this release.

⚠️ BREAKING CHANGE: This release removes the Last.fm shared API-key, as previously announced here.
If you use any Last.fm functionality (scrobbling, biographies, album descriptions), please check the documentation on how to create your own API Key, it is free and should only take you a couple of minutes. NOTE: Remember to re-enable scrobbling after changing the API Key and restarting the server.

In this release we focused on support and compatibility with OpenSubsonic, increasing the overall user experience when using a compatible Subsonic client. Click here for the full list of what is implemented and what is missing for now.

NOTE: Even though this release does not force a full rescan, you should do it at your discretion, to import more tags available in the scanner, ex: structured lyrics."
