SiYuan
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
A side-by-side editorial comparison of CommaFeed and pagedown — 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.
pagedown is down to one small fix a year, mostly absorbing changes from elsewhere.
The last six releases contain no new capability. 0.24 fixes missing horizontal rules under unnumbered h1 headers in the poster_jacobs format; 0.23 stops non-ASCII header text erroring during TOC processing; 0.22 drops a call to `xfun::attr()` before it disappears upstream; 0.21 sets an `is.paged.js` knit option so knitr knows paged.js loads its own JS and CSS; 0.20 raises the R floor; 0.19 patches a browser rendering regression with `overflow-x: clip`.

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.

pagedown sits between three things it does not control — paged.js, headless Chrome, and Pandoc — and its release history is a record of each of them moving. The one release in the window with anything resembling design intent is 0.21, which lets other packages detect a paged.js context rather than guess it. Cadence has thinned to roughly one release a year, and the last genuinely new features (long-table headers, Sass support, streamed PDF transfer) are outside this window.
Expect another single-fix release triggered by a paged.js, Chrome or Pandoc change. Nothing here suggests new output formats are coming.
