Kubernetes note people miss: AgentgatewayModel is experimental and off by default. Higher-level than hand-wiring backends + HTTPRoutes. Existing APIs stay. Upgrade first. Pilot one non-prod model second.

I matched my agentgateway 1.4.0 write-up to the official release notes. Not just features — breaking changes + a High severity MCP auth advisory too. If you skimmed 1.4 as “nice UI stuff,” read this thread.

A few upgrade notes so nobody gets surprised: • bump CRDs before controller/proxy • standalone chart/values changed — read them • musl images are gone • DaemonSet gateways exist if you need node-local Blind helm upgrade is a bad idea on this one.

agentgateway 1.4.0 shipped today. I went through everything between 1.3.0 and 1.4.0 and wrote up what actually matters if you run this in the real world — not every PR, just the stuff that changes day-2 ops. 🧵
