What is CoScreen?

CoScreen ships its final build and declares End of Life after a year of quiet.

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

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.

CoScreen ships its final build and declares End of Life after a year of quiet.

◆ Current state

CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.

◆ Where it's heading

The cadence tells the story: steady usability and performance work through 2024 and into early 2025, a last genuine feature drop in August 2025, then silence until today's EOL. This is a sunset, not a pivot. Users can expect the app to keep running on 8.11.14 but to receive no further fixes or OS-compatibility updates.

◆ Prediction

With EOL declared and a final build shipped, the only moves left are wind-down mechanics: a hard shutdown date, export or migration guidance, and eventual removal from distribution. No further feature work is coming.

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.
