What is Document360?
Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.
Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.
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.

Document360
6.3COLLAB
Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.
◆ Current state
Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.
◆ Where it's heading
Two threads run through the year. One makes the knowledge base machine-readable and machine-writable: MCP server, automatic llms.txt, open-an-article-in-ChatGPT-or-Claude, then API v3. The other fences that access with admin controls before enterprise buyers have to ask. The newest release turns the AI inward for the first time — the redesigned Publish dialog puts suggestions and validation in the author's path rather than the reader's, which is a different customer for the same capability.
◆ Prediction
The AI suggestions now sitting in the Publish dialog are the obvious candidate to move into the editor itself, and the advanced v3 endpoints sold as an add-on look like the seed of a higher API tier. The Widget 2.0 forced migration is the near-term execution risk, since it puts required technical work on existing customers to a fixed timeline.
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.
