Versie 12.0 van Jellyfin is uitgekomen, als opvolger van versie 10.11. Deze mediaserver is een fork van Emby en is ontstaan nadat Emby closedsource werd en er voor zogenaamde premiumfeatures betaald moest gaan worden, zoals dat ook bij Plex het geval is. Jellyfin is echter volledig opensource gebleven en alle functionaliteit is aanwezig. Het draait op Windows, macOS, Linux of in een Docker-container. Verder zijn er clients voor elk OS, mediaspelers, tv's en mobiele apparaten. Uitgebreide informatie over de veranderingen in deze uitgave kan hier worden gevonden; dit is de inleiding daaruit:
Jellyfin 12.0We are pleased to bring you Jellyfin 12.0, our new stable release. This release continues in the same direction as 10.11: finishing what the database conversion started, turning that new foundation into real performance work, and finally giving books and comics the support they have deserved for years.
This release changes the database schema and actively rewrites data on first boot, so a backup is the only way back to your previous version.
- As always for major upgrades, ensure you STOP Jellyfin and take a FULL MANUAL BACKUP OF YOUR DATA AND CONFIG DIRECTORIES before upgrading!
- You must be running Jellyfin 10.10.7 or any 10.11.x release before upgrading to 12.0. Upgrading directly from 10.11.x is fully supported and no intermediate step is needed. If you are on anything older than 10.10.7, upgrade to 10.10.7 first, then upgrade to 12.0.
- Check your usernames before upgrading. Usernames are now case insensitive, so two accounts can't have names that only differ by capitalization. If you have users that match this pattern the database migration will fail.
- A full library scan is REQUIRED after upgrading. As part of fixing how alternate versions are stored, versions that Jellyfin grouped automatically, not ones you merged yourself, are cleared during the upgrade. Until you run the scan those versions will look like they are missing.
- The first scan after upgrading will take significantly longer than normal, and some movies may appear as newly added. This is expected. Jellyfin now checks every item in your library against the files on disk to clear out leftovers from previous versions, and anything that was previously filed incorrectly gets corrected as it goes. Do not stop the server while migrations are running.
- Once installed, please ensure you hard refresh (e.g. Ctrl+Shift+R or similar) and/or clear your web cache for your Jellyfin instance if you notice any UX anomalies. Bad cached assets are the #1 cause of such issues.
- Remove any third-party plugins before upgrading. Plugins built for 10.11 will not load on 12.0 and need updated builds from their authors, so give them time to catch up before adding them back. Official plugins have been updated for 12.0 support.
- Very old third-party clients will stop working. Support for the legacy
/emby/and/mediabrowser/addresses has been removed, and the deprecated way of signing in is now disabled, including on existing servers. Clients that have not seen an update in years are the ones at risk here.- This release contains security fixes, so we recommend upgrading rather than staying on an older release once you are ready.
- As always with major Jellyfin releases, bugs will exist. Please prefix bug reports with "[12.0]" so we can triage them quickly, and see point 1 one more time: take a backup.
