What is Mattermost?

Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.

Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.

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`.

Mattermost vs pagedown: editorial side-by-side

M5.0

Every v11 release pushes ABAC further out; the blog sells the air-gap story around it.

◆ Current state

Mattermost ships a v11.x release roughly monthly, and each one extends attribute-based access control another layer: v11.9 reached channel-level policies and ranked attributes, v11.10 adds team-level ABAC membership and native user attributes. Between releases the feed is marketing content aimed at defense, federal, and other air-gapped buyers. The product work and the publishing calendar are pulling in the same direction.

◆ Where it's heading

ABAC is being built out as the organizing primitive — first channels, now teams, with user attributes moving from an integration concern into the platform itself. The surrounding posts on agentic AI in disconnected environments read as demand-shaping for the AI features shipping in the same releases. Expect the two lines to converge on running agents inside a network that cannot call out.

◆ Prediction

The next v11 release should extend ABAC to a further scope or add policy administration tooling, and the agent features will keep being framed around operating without external model APIs.

0.0

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.
