Introduction

Jellyfin, the open-source media server competing with Plex and Emby, has just released version 12.0, bringing a host of notable improvements and new features. This release marks a significant milestone in Jellyfin's evolution, particularly with performance optimization and the introduction of long-awaited support for books and comics.

Key Enhancements

Database Optimization

One of the standout improvements in Jellyfin 12.0 is the overhaul of the database. This update changes the database schema and actively rewrites data upon first boot, necessitating a full backup before upgrading. This overhaul results in improved performance, especially for metadata processing and search queries.

Support for Books and Comics

Jellyfin 12.0 finally addresses the demands of many users by integrating enhanced support for books and comics. This feature allows for better organization and visualization of collections, making Jellyfin an even more comprehensive media platform.

Library Scan

After the upgrade, a full library scan is required. This process ensures that all alternative versions are correctly stored and that any leftover files from previous versions are cleaned up.

Upgrade Guidelines

Before upgrading to Jellyfin 12.0, it is crucial to follow certain steps. Make sure to back up your data and verify that you are running at least version 10.10.7. Additionally, since usernames are now case insensitive, check that there are no accounts with names differing only by capitalization.

Conclusion

Jellyfin 12.0 represents a significant advancement for users looking to maximize the efficiency and reach of their personal media servers. With significant improvements in the database and the addition of features for books and comics, this upgrade is a must. Ready to make the move?
