Mattermost adds Matrix Protocol federation and dual ABAC controls for Enterprise
What happened
Between the Aug 10, 2026 and Aug 17, 2026 captures of Mattermost's pricing page, Pulse recorded one change: Enterprise gains a Matrix Protocol federation integration for bidirectional cross-server sync, and Enterprise Advanced gains two new ABAC (Attribute-Based Access Controls) capabilities: team-level ABAC membership policies and native built-in user attributes. Pulse files it as a product change (feature added) with an upward direction.
It lands 45 days after Mattermost's previous change, "Mattermost: Professional plan capped at 250 users; Enterprise Agentic Platform adds new agent tooling" (Jul 3, 2026). Before that Pulse recorded "Mattermost adds classified channel marking schemes for enterprise teams" (Jun 22, 2026). Mattermost has been tracked since 2023-11-15.
In the same window Microsoft, Nextcloud and Rocket.Chat also changed their Collaboration & Productivity pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
