 - `ServerSideFieldValidation`: Enables server-side field validation. This means the validation
   of resource schema is performed at the API server side rather than the client side
   (for example, the `kubectl create` or `kubectl apply` command line).
+- `ServiceNodePortStaticSubrange`: Enables the use of different port allocation
+  strategies for NodePort Services. For more details, see
+  [reserve NodePort ranges to avoid collisions](/docs/concepts/services-networking/service/#avoid-nodeport-collisions).
 - `SidecarContainers`: Allow setting the `restartPolicy` of an init container to
   `Always` so that the container becomes a sidecar container (restartable init containers).
