What is Excalidraw?

Excalidraw library cadence is glacial — v0.18 in March 2025, then silence; feed is mostly GitHub-profile noise.

The captured changelog tracks the npm library at github.com/excalidraw/excalidraw, not the hosted app at excalidraw.com. The library has shipped four substantive releases over two-and-a-half years: v0.16.1 (Sep 2023), v0.17.0 (Nov 2023), v0.17.3 (Feb 2024), and v0.18.0 (March 2025). The latest entry is from April 2026 but is a GitHub-profile scraping artifact, not a release. Half the feed is GitHub user-profile pages ('Sorry, something went wrong') that landed instead of release content.

What is Mattermost?

Mattermost ships v11.8 compliance controls amid heavy sovereign-defence content

Mattermost's feed mixes genuine releases with a steady stream of sovereign-collaboration and defence thought-leadership essays and partnership PR (Whitespace, archTIS, Arqit). The substantive release this window is v11.8 — classification banners, automated data-spillage reporting, and mobile ephemeral mode — squarely aimed at regulated and mission-critical operators.

Excalidraw vs Mattermost: editorial side-by-side

Excalidraw logo1.3

Excalidraw library cadence is glacial — v0.18 in March 2025, then silence; feed is mostly GitHub-profile noise.

◆ Current state

The captured changelog tracks the npm library at github.com/excalidraw/excalidraw, not the hosted app at excalidraw.com. The library has shipped four substantive releases over two-and-a-half years: v0.16.1 (Sep 2023), v0.17.0 (Nov 2023), v0.17.3 (Feb 2024), and v0.18.0 (March 2025). The latest entry is from April 2026 but is a GitHub-profile scraping artifact, not a release. Half the feed is GitHub user-profile pages ('Sorry, something went wrong') that landed instead of release content.

◆ Where it's heading

v0.18.0 was the high-water release — command palette, multiplayer undo/redo, editable element stats, text wrapping, and laser pointer. Since then the library has been quiet for over a year while the hosted app at excalidraw.com presumably continued to evolve through unversioned deploys. This pattern suggests the team has shifted investment toward the SaaS product and integrations, with the open-source library treated as a stable embedding target rather than the frontier of feature work.

◆ Prediction

The library will likely see another minor release rather than going dormant — there is too much downstream embedding (Notion, Obsidian, etc.) for it to fully fall behind the SaaS app — but expect months between releases, not weeks. The feed-source issue is fixable: the crawler should target the GitHub Releases API or RSS, not the HTML release pages and contributor profiles that produce the current noise.

Mattermost ships v11.8 compliance controls amid heavy sovereign-defence content

◆ Current state

Mattermost's feed mixes genuine releases with a steady stream of sovereign-collaboration and defence thought-leadership essays and partnership PR (Whitespace, archTIS, Arqit). The substantive release this window is v11.8 — classification banners, automated data-spillage reporting, and mobile ephemeral mode — squarely aimed at regulated and mission-critical operators.

◆ Where it's heading

Mattermost is doubling down on secure, self-hosted collaboration for defence, government, and regulated industries — compliance tooling in the product, sovereign-AI and post-quantum partnerships around it. The product arc is incremental hardening of an already security-focused platform; the directional bets show up as partnerships and essays more than as single releases.

◆ Prediction

Expect continued compliance and data-governance features in point releases, with more defence-sector partnership announcements framing the strategy.
