Why jump from 10.11.11 directly to 12.0? -> Blog Post
You can find more details about and discuss this release on the official forums.
As always, please ensure you stop your Jellyfin server and take a full backup of your metadata/configs before upgrading!
Direct upgrades from 10.10.7 and 10.11.x to 12.0 are supported; intermediate upgrades are not required. Users running releases older than 10.10.7 are strongly encouraged to upgrade to 10.10.7 before migrating to 12.0.
Installed repository plugins (anything not built-in) should also be removed before migrating. Plugins will likely need time to adapt to the new database changes, so re-adding them afterward is the safest approach for testing.
Official plugins compatible with Jellyfin are available through the stable plugin repository. If you have changed to the unstable plugin repository please change it back.
Go to Dashboard -> Plugins -> Manage Repositories Update the Plugin Repository URL to: https://repo.jellyfin.org/files/plugin/manifest.jsonAfter migrating please perform the following steps.
Perform a full library scan to restore alternative versions Run the "Optimize database" scheduled task___


I’ve been using Jellyfin for years, on different hosts. Music has never worked on any of my devices - there’s a bug where you try to play a track and it ignores you and plays the first track off the album instead. You can literally never play anything after that. To be fair, I haven’t tested this in six months, but it was a consistent bug for years before that and I’ve tried every client under the sun. Nowadays I use Jellyfin for video and Navidrome for audio instead and it’s all good.
