The official source reports this update: v3.0.6. Changelog New Features Stateless MCP serving. MCPConfig(stateless=True) serves /mcp without session tracking, so any replica can answer any request and a multi-instance deployment needs no session affinity. Costs server-initiated notifications and SSE resumability, so it stays off by default. See cookbook . MCPTools(protocol_mode=...) selects which MCP protocol era to negotiate. Defaults to "legacy" , preserving today's session-based behaviour; "auto" negotiates the newest era both sides support (sessionless from 2026-07-28 ). Existing servers are unaffected — a modern server still accepts the legacy handshake.
