Mattermost vs Notion: at a glance
What is Mattermost?
Attribute-based access control keeps climbing a layer per release; the AI agents get failure handling.
Mattermost ships a v11.x release roughly monthly and each one pushes attribute-based access control one layer further out: v11.9 took ABAC to channel-level policies, v11.10 takes it to team membership and lets admins write policies against native user attributes instead of standing up an identity integration first. Between releases the feed is almost entirely thought-leadership aimed at defense and regulated buyers - zero trust, air-gapped networks, data sovereignty. The AI agent work has moved past capability into reliability, with dynamic tool calling, on-demand file context, and automatic fallback when a model goes down.
What is Notion?
Every release now lands on the agent: what triggers it, what it can reach, what it costs.
Since Notion 3.6 shipped External Agents, essentially the whole changelog has been agent infrastructure. Custom Agents gained a meeting-note trigger, calendar tools, and a one-click path to share docs into their context; Workers got usage tracking in the credits dashboard ahead of the beta ending; and the model picker now exposes scorecards for speed, intelligence and cost with a per-request effort dial. The one non-agent item in the window is high contrast mode.

Mattermost
5.0COLLAB
Attribute-based access control keeps climbing a layer per release; the AI agents get failure handling.
◆ Current state
Mattermost ships a v11.x release roughly monthly and each one pushes attribute-based access control one layer further out: v11.9 took ABAC to channel-level policies, v11.10 takes it to team membership and lets admins write policies against native user attributes instead of standing up an identity integration first. Between releases the feed is almost entirely thought-leadership aimed at defense and regulated buyers - zero trust, air-gapped networks, data sovereignty. The AI agent work has moved past capability into reliability, with dynamic tool calling, on-demand file context, and automatic fallback when a model goes down.
◆ Where it's heading
The ABAC arc is the spine of this product right now, and it is being built outward from a single policy engine rather than bolted onto each surface separately - channels, then teams, then the attribute source itself. Dropping the integration requirement for user attributes is the tell: Mattermost wants ABAC to be configurable by an admin in an afternoon, not a deployment project. The agent features are converging on the same buyer, since a model that silently fails is not deployable in the environments this release notes are written for.
◆ Prediction
The next release most likely extends ABAC to a further object - playbooks, boards, or integrations - or adds policy simulation and audit tooling, since admins writing policies across three scopes now need a way to see what a rule will actually block before it blocks it.
Notion
6.3PMCOMMS
Every release now lands on the agent: what triggers it, what it can reach, what it costs.
◆ Current state
Since Notion 3.6 shipped External Agents, essentially the whole changelog has been agent infrastructure. Custom Agents gained a meeting-note trigger, calendar tools, and a one-click path to share docs into their context; Workers got usage tracking in the credits dashboard ahead of the beta ending; and the model picker now exposes scorecards for speed, intelligence and cost with a per-request effort dial. The one non-agent item in the window is high contrast mode.
◆ Where it's heading
Notion is assembling the unglamorous half of an agent platform - triggers, permissions, connections, metering - rather than adding capabilities. The sequencing is deliberate: agents that can act on your calendar and fire off meeting notes need a permission model and a visible bill before anyone runs them on a team. Surfacing model cost and effort to the end user points the same way, pushing the spend decision down to whoever writes the prompt.
◆ Prediction
The Workers beta ending is the next dated event to watch, and pricing for it is the likeliest announcement; expect further agent triggers beyond meeting notes and more connected tool surfaces on the calendar pattern.
