What is Flarum?

Flarum's 2.0 has been in release-candidate territory for most of a year.

Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.

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.

Flarum's 2.0 has been in release-candidate territory for most of a year.

◆ Current state

Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.

◆ Where it's heading

The substance that is visible points at making large forums viable: eliminating N+1 queries on the discussion list, adding a composite index to fix slow unread-notification counts, and caching scheduler timestamps. Those are the changes a forum makes when instances have outgrown the original query patterns. The steady RC cadence with no beta regression suggests a stabilisation grind rather than continued feature work — but the opaque release notes make the remaining scope hard to read from outside.

◆ Prediction

A 2.0 stable release is the obvious next step, though five candidates without a published scope makes the timing unclear. Watch whether rc.6 arrives on the same three-to-six week spacing or the gap widens.

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.
