Short version: not yet, and that's deliberate. SparkBox ships a tested-stable Jellyfin pin rather than chasing the upstream major — right now that's 10.11.11 for every box (both the Media Center bundle and the standalone app). I checked the published SparkBox releases and none has moved the default to 12.0, so there's no action to take; when 12.0 has been verified against the bundle it will arrive through a normal SparkBox upgrade. If you'd like to run 12.0 before it becomes the default, there's a supported opt-in in the per-app overrides guide. Create state/overrides/media.yml in your SparkBox install with: services: jellyfin-media: image: jellyfin/jellyfin:12.0-rc1 healthcheck: startperiod: 300s Then run sudo sparkbox up media. Jellyfin backs up its database before it migrates, so it's reversible: to roll back, delete that file (or set the image back to 10.11.11) and run sudo sparkbox up media again. Expect rough edges while it's a release candidate — if you try it, please report anything odd so it can be fixed before 12.0 becomes the default.
