Answer
Components allow limited version skew; mismatches destabilize clusters.
Quick Answer
Kubernetes enforces strict version skew limits between components — typically no more than 2 minor versions between API server and kubelet. Upgrading the API server too far ahead of the kubelet can cause incompatibilities where the kubelet can't process new API features. Upgrade control plane first, then nodes, one version at a time.
