Elgg vs Mattermost: at a glance
What is Elgg?
A social-networking engine in careful maintenance across two supported branches.
Elgg is running a two-branch release cadence: a 7.0.x line taking bug fixes and a 6.3.x line receiving backports. The recent pairs shipped within two hours of each other — 7.0.5 carrying a single performance fix that stops likes generating ajax response data for unsupported entities, while 6.3.8 carries the longer list: improved sanitization of installer config values, a valid client IP for the core, embedded-image handling in notification emails, mute-option validation, and a permission check before a profile header image can be changed. Contributor counts stay in the low single digits with the same one or two maintainers on nearly every release.
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.

Elgg
5.0COLLAB
A social-networking engine in careful maintenance across two supported branches.
◆ Current state
Elgg is running a two-branch release cadence: a 7.0.x line taking bug fixes and a 6.3.x line receiving backports. The recent pairs shipped within two hours of each other — 7.0.5 carrying a single performance fix that stops likes generating ajax response data for unsupported entities, while 6.3.8 carries the longer list: improved sanitization of installer config values, a valid client IP for the core, embedded-image handling in notification emails, mute-option validation, and a permission check before a profile header image can be changed. Contributor counts stay in the low single digits with the same one or two maintainers on nearly every release.
◆ Where it's heading
This is a mature project maintaining a stable base rather than pushing new capability, and the balance between the branches is worth noting: the older 6.3 line is receiving more substantive hardening than the current 7.0 line, which has already settled into single-commit patches. That is what a project looks like when most of its deployments have not migrated yet. The 6.3.8 items — input sanitization, permission validation before a mutating action — are the security-shaped fixes that earlier 6.3 releases summarised only as 'small security update'.
◆ Prediction
Expect the alternating pattern to continue: 7.0.x patches as issues surface, with matching 6.3.x backports carrying the hardening work, until a 7.1 cycle opens. The entries give no indication of when that might be.
Mattermost
5.0COLLAB
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.
