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.

What is Nextcloud?

Nextcloud runs three LTS branches in parallel, shipping bug fixes and quiet performance wins.

Nextcloud is simultaneously maintaining three major release lines (32.x, 33.x, 34.x), publishing patch updates every few weeks. Recent work fixes file-sharing edge cases, corrects share permission logic, and patches OCM federation bugs. Performance work targets group membership lookups, swapping full group-object fetches for leaner ID-only queries across branches.

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.

5.0

Nextcloud runs three LTS branches in parallel, shipping bug fixes and quiet performance wins.

◆ Current state

Nextcloud is simultaneously maintaining three major release lines (32.x, 33.x, 34.x), publishing patch updates every few weeks. Recent work fixes file-sharing edge cases, corrects share permission logic, and patches OCM federation bugs. Performance work targets group membership lookups, swapping full group-object fetches for leaner ID-only queries across branches.

◆ Where it's heading

The three-track maintenance cadence signals a hardening phase following v34's release, prioritizing stability over new surface area. OCM fixes accumulating across branches suggest cross-instance federation use is growing and generating real-world bug reports. If this pattern holds, a v35 feature push is the next inflection point — the current batch is largely invisible to end users.

◆ Prediction

The next meaningful surface change will likely come with v35 feature work; the cross-branch group-query performance push and OCM federation fixes hint that enterprise scale and cross-instance collaboration are the focus areas going into the next major.
