The Model Context Protocol team published an updated roadmap this week, and it's worth reading beyond the headline. The previous roadmap from March targeted four areas: transport evolution, agent communication, governance, and enterprise readiness. They delivered on all four.
The changes landed in the 2026-07-28 spec release — and the biggest one is architectural.
"Protocol-level sessions and the initialization handshake are gone, so a server can scale horizontally without holding state."
That's not a minor tweak. That's MCP crossing from "interesting protocol" to "just another HTTP workload you can run anywhere."
