What is HumHub?

HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.

The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.

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.

5.0

HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.

◆ Current state

The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.

◆ Where it's heading

The 1.19 cycle is being spent making the migration survivable on real installations rather than adding capability, which is the usual shape when a schema and directory-layout change meets databases and webroots that have accumulated years of drift. Beta.2 extends that into the installer itself, where an unreachable database was offering to re-set-up a live instance during a transient outage. The permission and visibility fixes point the same way: tightening authorisation and content boundaries is cleanup of an existing model, not an extension of it.

◆ Prediction

Only beta tags appear in this feed, so a 1.19.0 stable is the obvious next milestone, but nothing here dates it. The beta.1-to-beta.2 gap of about a month is a faster rhythm than the roughly six months between the 1.18 and 1.19 betas.

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.
