 Feature gate descriptions:
 
+`ControlPlaneKubeletLocalMode`
+: With this feature gate enabled, when joining a new control plane node, kubeadm will configure the kubelet
+to connect to the local kube-apiserver. This ensures that there will not be a violation of the version skew
+policy during rolling upgrades.
+
 `EtcdLearnerMode`
 : With this feature gate enabled, when joining a new control plane node, a new etcd member will be created
 as a learner and promoted to a voting member only after the etcd data are fully aligned.
