A side-by-side editorial comparison of Mattermost and tufte — release velocity, themes, recent moves, and the top alternatives to consider.
Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.
Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.
After three quiet years, tufte 0.15 finally lets Tufte-style documents cross-reference.
Almost every release before the latest is a Pandoc compatibility fix — sidenotes breaking on Pandoc 2.15, margin references misplaced on 2.11, table and citation handling in `tufte_handout()`, `--wrap preserve` for margin content on 2.19. Then 0.15.0 in May 2026 breaks the pattern: `tufte_handout2()`, `tufte_book2()` and `tufte_html2()` wrap the corresponding bookdown formats, enabling text references and cross-references in captions, and `margin_fig_pos` gives global control over margin-figure placement.

ABAC is being built out as the organizing primitive — first channels, now teams, with user attributes moving from an integration concern into the platform itself. The surrounding posts on agentic AI in disconnected environments read as demand-shaping for the AI features shipping in the same releases. Expect the two lines to converge on running agents inside a network that cannot call out.
The next v11 release should extend ABAC to a further scope or add policy administration tooling, and the agent features will keep being framed around operating without external model APIs.

The package spent years absorbing upstream Pandoc churn without adding anything, and has now moved to sit on top of bookdown rather than reimplement around it. That is the sustainable direction for a format package this small: inherit cross-referencing and text references instead of maintaining a parallel implementation. Release intervals remain long, so this is unlikely to become a fast-moving package.
Expect the bookdown-backed formats to absorb further fixes as the recommended path, with the plain `tufte_*()` formats staying frozen against Pandoc changes.
