- Kubectl apply: warning that kubectl will ignore no-namespaced resource `pv & namespace` in a future release if the namespace is specified and allowlist is not specified. ([#110907](https://github.com/kubernetes/kubernetes/pull/110907), [@pacoxu](https://github.com/pacoxu))

- Kube-apiserver: ensures the namespace of objects sent to admission webhooks matches the request namespace. Previously, objects without a namespace set would have the request namespace populated after mutating admission, and objects with a namespace that did not match the request namespace would be rejected after admission.

- Return a warning when applying a `pod-security.kubernetes.io` label to a PodSecurity-exempted namespace.
  Stop including the `pod-security.kubernetes.io/exempt=namespace` audit annotation on namespace requests. ([#109680](https://github.com/kubernetes/kubernetes/pull/109680), [@tallclair](https://github.com/tallclair))
