Key points

Jellyfin 12.0 Release Overview
Jellyfin has announced the stable release of version 12.0. This update focuses on completing the database conversion initiated in previous versions, translating that new foundation into performance improvements, and providing better support for books and comics within the media server.
Critical Upgrade Information
Upgrading to Jellyfin 12.0 requires careful attention to specific instructions. The release changes the database schema and rewrites data upon the first boot, making a full manual backup of data and configuration directories essential before proceeding. Users must be running Jellyfin 10.10.7 or any 10.11.x release prior to upgrading to 12.0.
Database and Library Changes
A significant change in Jellyfin 12.0 is the introduction of case-insensitive usernames; users with accounts differing only by capitalization must resolve this before upgrading to avoid migration failure. A full library scan is mandatory after the upgrade, as alternate versions grouped automatically by Jellyfin will be cleared. The initial scan will take longer than usual as the system checks every item against files on disk and corrects previous inaccuracies.
Post-Upgrade Steps
After installation, users are advised to perform a hard refresh or clear their web cache for the Jellyfin instance if they encounter any user experience anomalies. This step helps resolve issues caused by outdated cached assets.
