+## SDK Compatibility Guarantees
+In order to allow compatibility between game server binaries and `sdk-server`, a game server binary
+using Beta and Stable SDK protos must remain compatible with a newer `sdk-server`. Why? SDK proto
+compatibility is crucial to reducing toil on our users. We don’t want to require users to redeploy
+binaries every release (6w!), and like to encourage upgrades as much as possible.
