Zoho Sign
Zoho Sign adds the EU's highest signature tier, one week after wiring itself to agents.
A side-by-side editorial comparison of CommaFeed and tufte — release velocity, themes, recent moves, and the top alternatives to consider.
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
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.

Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.

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.
