Jellyfin 12.0

Jellyfin 12.0 is a major stable release that rewrites the database schema on first boot, requiring a full manual backup and a complete library scan after upgrade. Users must run version 10.10.7 or later, ensure usernames are case-insensitive, remove incompatible plugins, and note that legacy /emby/ and /mediabrowser/ client endpoints are no longer supported. The update also adds security fixes and official plugin support for the new version.
