What happened
Jellyfin 10.11.7, released on 31 March 2026, fixed four important security vulnerabilities. The project advised users of every earlier server version to update immediately.
Version 10.11.8 followed on 5 April to fix regressions from 10.11.7. Jellyfin 10.11.9 added playback and user-management fixes, 10.11.10 added three more security fixes, and 10.11.11 followed with another user-management fix.
As of 13 August 2026, 10.11.11 is the latest stable Jellyfin Server patch.
Jellyfin also confirmed that 10.11 is the final branch using the permanent 10. prefix. The next major server release is 12.0, not 10.12.
Who is affected
Act now if your Jellyfin dashboard reports:
- a version earlier than 10.11.7
- an intermediate 10.11 patch when a later stable patch is available
- an unknown or unrecorded server version
Also review documentation, scripts or notes that refer to a future “Jellyfin 10.12”.
What to do
- Record the installed version and installation method.
- Read the official release notes between that version and the newest stable 10.11 patch.
- Take an offline backup of Jellyfin data and configuration.
- Update only Jellyfin during the maintenance window.
- Follow startup logs and verify users, libraries, playback, plugins and remote access.
- Keep the previous application reference and backup until the update proves stable.
Do not deliberately target 10.11.7 or 10.11.10 when a later stable 10.11 patch is available through the normal channel.
Jellyfin 12
Jellyfin 12 remains a separate major migration. Reaching a healthy 10.11.11 server is sensible preparation, but it does not replace the Jellyfin 12 backup, plugin and migration checks.
