The MCP team shipped the RC for the next spec, and the headline is statelessness at the protocol layer via six coordinated SEPs, plus an Extensions framework, Tasks, MCP Apps, authorization hardening, and a formal deprecation policy. Source: Model Context Protocol Blog The practical win is real: remote MCP servers that needed sticky sessions can now run behind a plain round-robin load balancer, and clients can cache tools/list per a server ttlMs. There are breaking changes with a ten-week validation window, final ships July 28. If you operate MCP infrastructure, start reading now, this is a re-architecture, not a point release.
