- Graduate MatchLabelKeys/MismatchLabelKeys feature in PodAffinity/PodAntiAffinity to Beta ([#123638](https://github.com/kubernetes/kubernetes/pull/123638), [@sanposhiho](https://github.com/sanposhiho)) [SIG API Machinery, Apps, Scheduling and Testing]

- The Kubernetes apiserver now emits a warning message for Pods with a null labelSelector in podAffinity or topologySpreadConstraints. The null labelSelector means "match none". Using it in podAffinity or topologySpreadConstraint could lead to unintended behavior.
