I was finally able to find time to update Subsonic-Fluid with support for Subsonic 6. You can find the new script in the existing repo.
Please make sure to use the subsonic6.js version. I’m leaving the old version in the project just in case someone still needs it.
Now if we could only get the last.fm bug in the v6 HTML player fixed all would be well in the universe once again. Please let me know if you have any questions or run into any issues.
