Outline
Outline gave AI assistants write access to the wiki, then spent months on the human side.
A side-by-side editorial comparison of Whimsical and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
Whimsical rebuilt itself as a diagramming surface agents can drive, then went back to polishing the canvas
The agent work landed in two steps: April put Whimsical inside ChatGPT and shipped a remote MCP server reachable from Claude, Cursor and other agents without the desktop app; July shipped Ask Whimsical, an in-product AI agent that creates diagrams, wireframes and mind maps and searches the workspace. Since then the releases have gone back to craft — dark mode across whiteboarding and embeds, Turbopuffer-backed search, icons inside flowchart shapes, snappier elbow connectors, SVG export and a Linux desktop app. MCP coverage keeps widening, most recently to editable doc tables.
A mature media server whose releases are format edge cases and Kobo plumbing.
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.

Whimsical is treating the agent as a second class of user with the same rights as a person: everything reachable in the UI is progressively becoming reachable over MCP, and the doc tables becoming editable rather than readable is the tell. Meanwhile the human-facing work targets the reasons people leave a diagramming tool — search that finds things across a large workspace, exports that survive the trip elsewhere, and a canvas that is comfortable to sit in for hours. The two tracks are not competing for the same roadmap slots, which suggests both are considered core.
Expect MCP write coverage to keep expanding toward boards and wireframes, matching what Ask Whimsical can already do in-product, and for the ChatGPT integration to be joined by equivalents in other assistant surfaces given the remote MCP server already makes that cheap.

The work concentrates where a self-hosted library server actually breaks: malformed EPUBs, archive formats readers assume will just open, and the sync protocols third-party devices speak. Kobo integration keeps taking attention — content restriction enforcement, proxying raw request bodies to the Kobo store — which suggests e-reader compatibility is where the user pressure sits. Translation batches from Weblate appear in most releases.
Expect more format-tolerance work on EPUB and archive handling, with the Kobo and KOReader integrations continuing to absorb the fixes that a mature library server accumulates.

noVNC ships about once a year, and its betas and finals carry identical notes.
Lidarr's release notes still tell you not to update Radarr — the fork's seams are showing.
