SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
A side-by-side editorial comparison of Mattermost and tufte — release velocity, themes, recent moves, and the top alternatives to consider.
Access control keeps getting finer-grained for defense buyers, buried in a blog that mostly publishes essays.
Most of this feed is editorial aimed at defense, government, and critical-infrastructure audiences — air-gapped networking, Zero Trust gaps in collaboration tooling, sensitive-data translation, mobile data protection. The actual product news arrives as periodic version digests. The most recent, v11.9, adds channel-level ABAC policies, ranked attributes, and program masking, plus native Azure Blob Storage so files stay in the infrastructure a team already runs.
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.

The product is pushing authorization granularity steadily downward — from server and team scope toward per-channel policy, with attribute ranking and masking to express which parts of a program a given user may see. That is a direct answer to the sovereignty argument the blog keeps making: perimeter and identity controls stop short of where the work happens. Storage is following the same logic, meeting customers inside their existing cloud tenancy rather than asking them to relocate data.
Expect the ABAC surface to keep extending into finer objects and administrative delegation, and further deployment-native storage and infrastructure integrations. The editorial run on agentic AI in mission-critical operations suggests agent governance is being positioned before it is shipped, though the release notes here do not yet show it.

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.
