The annotation that informs about audit policy violations changed from `pod-security.kubernetes.io/audit` to `pod-security.kubernetes.io/audit-violation`. ([#105908](https://github.com/kubernetes/kubernetes/pull/105908), [@stlaz](https://github.com/stlaz))

- The status of v1beta1 CRDs without "preserveUnknownFields:false" now shows a violation, "spec.preserveUnknownFields: Invalid value: true: must be false". ([#93078](https://github.com/kubernetes/kubernetes/pull/93078), [@vareti](https://github.com/vareti))

extensions/v1beta1 to the new networking.k8s.io/v1 API group. The structure remains unchanged from the v1beta1 API. The net.beta.kubernetes.io/network-policy annotation on Namespaces (used to opt in to isolation) has been removed. Instead, isolation is now determined on a per-pod basis. A NetworkPolicy may target a pod for isolation by including the pod in its spec.podSelector. Targeted Pods accept the traffic specified in the respective NetworkPolicy (and nothing else). Pods not targeted by any NetworkPolicy accept...

- Replaced *_admission_latencies_milliseconds_summary and *_admission_latencies_milliseconds metrics because they were reporting seconds rather than milliseconds. They were also subject to multiple naming guideline violations (units should be in base units and "duration" is the best practice labelling to measure the time a request takes). Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary, as these now report the unit as described,...
