What is Excalidraw?

Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.

This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.

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.

Excalidraw vs Komga: editorial side-by-side

Excalidraw logo0.0

Excalidraw's package went ESM-only in 0.18 — a big release, then 16 months of silence on this feed.

◆ Current state

This feed tracks the embeddable @excalidraw/excalidraw package rather than the hosted app, so every entry is a library release aimed at developers integrating the canvas. Version 0.18.0 in March 2025 was the large one: command palette, multiplayer undo and redo, flowcharts, elbow arrows, scene search, image cropping, element linking, CJK fonts, and a move from UMD to ES modules that broke existing consumers. Earlier releases are smaller, mostly programmatic API surface and rendering fixes. Nothing has been captured since.

◆ Where it's heading

The package's direction has been to expose more of the editor to host applications — API subscribers, programmatic element creation, viewport control, sidebar tabs — so Excalidraw can be embedded as a component rather than only used as a site. The ESM transition fits that: tree-shakable output matters to the teams shipping it inside their own products. With no releases captured in over a year, this source no longer says anything about current activity, which more likely reflects the crawl target than the project.

◆ Prediction

Insufficient data for a forward call from this feed: the last captured release predates the window by more than a year, so any prediction would be about the package's dormancy rather than Excalidraw's actual roadmap.

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.
