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 litedown — 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.
litedown grows from a lean renderer into a book and site generator
litedown is Yihui Xie's minimal R Markdown alternative, shipping every few months with a tight list of chunk options and rendering controls. Recent releases added output filtering, plot selection via fig.keep, offline HTML rendering, and context queries from inside chunks. The newest release adds book and website project templates discoverable from RStudio's New Project dialog.

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 is moving up a level: from rendering one document to scaffolding whole projects, which is the territory bookdown and blogdown occupy in the older stack. The chunk-option work continues underneath, consistently driven by named community requests rather than a roadmap.
Expect the book and site templates to gain the surrounding tooling — navigation, cross-file references, publishing helpers — that a project generator needs.
