Notion pages are indexed org-wide with page-level grants, incremental refresh on webhook, and a revocation sweep that retracts brain copies when a grant goes away.
Fathom connects per user rather than per org, with an optional pinned brain.
Artifact file-bundle storage with a version tree, plus external-MCP file uploads and a file-serve endpoint.
Routine trigger types split into schedule and event.
Referral summary endpoint.
MCP server — create_skill authors a skill from chat or Claude Code.
MCP server — read-only list_skills and get_skill.
MCP server — share a skill into an agent brain.
MCP server — recall_directives for team-stack directive recall.
Improvements4
Chat explains its tool calls as it works instead of going quiet.
Agent brains can be selected in chat and are searched without being asked for.
All sources moved under Brains.
Slack notifications default on for teammates.
Fixes4
Chat — the loop runs on the Responses API, fixing reasoning and tool-call handling; bounded DB and Redis operations stop a hanging conversation.
GitHub — deleting the integration uninstalls the app.
Email — routine deliverables render Markdown to HTML instead of emailing raw Markdown.
Billing — a first Pro org can check out directly.
Security1
Team documents — brain-scoped ingest is gated on brain access alone, and homed at the brain's own workspace.
