### AI overview

Jellyfin 12.0 introduces a new versioning scheme and a database rewrite that makes upgrading a consequential operation. Users must meet the supported upgrade path, back up and verify restoration of their configuration and database, complete a full library scan, remove or recompile third-party plugins, and account for removed legacy API and login support.

### Source excerpt

Jellyfin 12.0 shipped on September 7, 2026, after months stuck in release candidate limbo. It's the biggest Jellyfin release since the project forked from Emby in 2018, and the version number itself is the first clue: this build reports as 12.0, not 10.12.0. That's not a typo. Jellyfin has dropped the "10" major prefix that led its version numbers since the fork.
