Jellyfin, the open source media server, has released their 6th RC for version 10.11.0.
This is a preview release, intended for those interested in testing 10.11.0 before it’s final public release.
If you intend to test this, BE SURE you stop your Jellyfin server and take a full backup before upgrading!
WIP release notes here for now: https://notes.jellyfin.org/v10.11.0_features
See the GitHub link for more details and a full list of changes.
Well you would lose the watched status for all your media, as well as any custom settings and whatnot.
My plan, when the time comes to upgrade, is to copy the DB and bring up an isolated container using the copy, let the upgrade proceed in the background, then swap to the new container when the upgrade is done. That way there’s minimal downtime and no data loss.
