What is Jellyfin?

Jellyfin renumbers to 12.0 and spends the whole cycle paying down its backend rewrite.

Jellyfin is deep in a 12.0 release-candidate train — five RCs since late June — that exists almost entirely to stabilize the backend rewrite shipped in 10.11.0. The project also renumbered along the way: 10.11.x becomes 12.x, dropping a leading "10." that had made every release read as minor. The outgoing 10.11.x stable line is still getting fixes, but 10.11.11 is down to a single locking change.

What is Komga?

After two years of quiet fixes, Komga puts a whole new web UI in front of users.

Komga's recent history is almost entirely maintenance — archive-format edge cases, EPUB table-of-contents parsing, Kobo and OPDS compatibility, and a long tail of dependency bumps and translations. Release 1.26.0 breaks that pattern by shipping NextUI, a rewritten web interface, in beta and served alongside the existing one from the same server. The old UI remains the default, and the new one is reached from a sidebar link or a /next path, with a published list of what is still missing.

Jellyfin
COLLAB
5.0

Jellyfin renumbers to 12.0 and spends the whole cycle paying down its backend rewrite.

◆ Current state

Jellyfin is deep in a 12.0 release-candidate train — five RCs since late June — that exists almost entirely to stabilize the backend rewrite shipped in 10.11.0. The project also renumbered along the way: 10.11.x becomes 12.x, dropping a leading "10." that had made every release read as minor. The outgoing 10.11.x stable line is still getting fixes, but 10.11.11 is down to a single locking change.

◆ Where it's heading

The RC rounds are getting narrower as the train converges. RC1 was a cumulative dump covering the move to .NET 10, removal of legacy API route middleware and deprecated API members, and an HLS transcode seeking refactor; RC5 is batched database lookups and a fix for image endpoints upscaling past the source resolution. The 10.11.x branch is now being maintained mainly as an upgrade floor — 12.0 refuses to install on anything older than 10.10.7 and runs a multi-minute migration on first boot.

◆ Prediction

With RC5 down to query batching and individual endpoint fixes, a 12.0 final looks near — likely one or two more RCs at most. The plugin story is the loose end: the RCs still tell testers to disable external plugins and reinstall from the unstable repository, and that has to resolve before a general release.

6.3

After two years of quiet fixes, Komga puts a whole new web UI in front of users.

◆ Current state

Komga's recent history is almost entirely maintenance — archive-format edge cases, EPUB table-of-contents parsing, Kobo and OPDS compatibility, and a long tail of dependency bumps and translations. Release 1.26.0 breaks that pattern by shipping NextUI, a rewritten web interface, in beta and served alongside the existing one from the same server. The old UI remains the default, and the new one is reached from a sidebar link or a /next path, with a published list of what is still missing.

◆ Where it's heading

This is a staged frontend replacement rather than a cutover: two UIs on one web server, a v2 referential API landing in the same release to back the new client, and a hotfix a few hours later for NextUI CSS layers under Tomcat. The backend is simplifying in parallel — RAR5 support moved to plain Java and libarchive was dropped from the Docker image and the tray app, removing a native dependency from the build. Feature work outside the UI stays narrow and format-focused.

◆ Prediction

Expect a run of point releases closing the gaps in NextUI's feature list and hardening the two-UI serving path, with the beta label staying on until parity is reached. A default switch is unlikely before the missing features land.
