- 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.

- Achieved 2X performance improvement on both required and preferred PodAffinity. ([#76243](https://github.com/kubernetes/kubernetes/pull/76243), [@Huang-Wei](https://github.com/Huang-Wei))
