It's not yet officially published on subsonic.org, but Subsonic 6.1.3 is now available for download from
https://sourceforge.net/projects/subson ... onic/6.1.3
It contains some important bug fixes:
Bugfix: Avoid player getting stuck when playing transcoded tracks.
Bugfix: Externally modified tracks disappear in Subsonic.
Bugfix: Hide links, buttons etc in the web interface if a user is not allowed to play music.
Sorry for taking so long to address these issues!
I would be glad to get feedback on this before making the release official.
Thanks!
Sindre
