* PodSecurityPolicy admission sets `podsecuritypolicy.admission.k8s.io/admit-policy` and `podsecuritypolicy.admission.k8s.io/validate-policy` annotations containing the name of the policy that allowed a pod to be admitted. (PodSecurityPolicy also gained the ability to [limit hostPath volume mounts to be read-only](https://kubernetes.io/docs/concepts/policy/pod-security-policy/#volumes-and-file-systems).)
