pagedown vs SOGo
A side-by-side editorial comparison of pagedown and SOGo — release velocity, themes, recent moves, and the top alternatives to consider.
pagedown vs SOGo: at a glance
What is pagedown?
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`.
What is SOGo?
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.

pagedown is down to one small fix a year, mostly absorbing changes from elsewhere.
◆ Current state
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`.
◆ Where it's heading
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.
◆ Prediction
Expect another single-fix release triggered by a paged.js, Chrome or Pandoc change. Nothing here suggests new output formats are coming.
SOGo
2.5COLLAB
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
◆ Current state
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.
◆ Where it's heading
The pattern is a codebase whose input-handling surface is being systematically probed, largely by the community reporting to the project's bug address, and patched in batches. Release numbering has stopped being reliable as a timeline — 5.12.7 shipped after 5.12.8 — so version order tells you nothing about what a deployment contains. The two non-security releases in this window were both regression repairs from the security releases that preceded them, which is the cost of shipping fixes at this cadence.
◆ Prediction
Given four security batches in five months and CVE identifiers still being assigned retroactively, another batch on the same cadence is the most likely next release, with a regression patch following it.
