What probably matters to youSection of the release
What
New client resources are compiled in: deployments and session thread events with streaming (managed-agents-2026-04-01), dreams (dreaming-2026-04-21), tunnels and tunnel certificates (mcp-tunnels-2026-06-22), memory-store versions including redaction (agent-memory-2026-07-22), a binary skill-version download, and an MCP OAuth validation call on vault credentials. Messages, batches and token counting lift a user profile id field into a header.
