called more than once in a single admission evaluation.\n\nIfNeeded: the webhook will be called at least one additional time as part of the admission evaluation if the object being admitted is modified by other admission plugins after the initial webhook call. Webhooks that specify this option *must* be idempotent, able to process objects they previously admitted. Note: * the number of additional invocations is not guaranteed to be exactly one. * if additional invocations result in further modifications...

* The webhook admission plugin now works even if the API server and the nodes are in two separate networks,for example, in GKE.
The webhook admission plugin now lets the webhook author use the DNS name of the service as the CommonName when generating the server cert for the webhook.

- The `PodSecurity `admission plugin has graduated to `beta` and is enabled by default. The admission configuration version has been promoted to `pod-security.admission.config.k8s.io/v1beta1`. See https://kubernetes.io/docs/concepts/security/pod-security-admission/ for usage guidelines.

- The deprecated `SecurityContextDeny` admission plugin, which has been deprecated since `v1.27`, has been removed. It is recommended to use the Pod Security Admission plugin instead, which has been available since v1.25. Refer to the [Kubernetes documentation](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#securitycontextdeny) for more information.
