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?

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.

Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.

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

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.

◆ Current state

Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.

◆ Where it's heading

The project is running a long, deliberately cautious frontend migration: both UIs ship in the same binary, the feature gap is tracked publicly in an issue, and users opt in by URL. That arrangement should persist across several minor versions before the old WebUI is retired. The parallel v2 referential API suggests the rewrite is also being used to revise the server contract rather than only restyle the client.

◆ Prediction

Near-term releases should keep closing the NextUI feature gap issue by issue, with patch releases landing within days of each other. The old WebUI is unlikely to be removed before NextUI reaches parity and browser refresh stops falling back to it.
