- The `AdmissionReview` API sent to and received from admission webhooks has been promoted to `admission.k8s.io/v1`. Webhooks can specify a preference for receiving `v1` AdmissionReview objects with `admissionReviewVersions: ["v1","v1beta1"]`, and must respond with an API object in the same `apiVersion` they are sent. When webhooks use `admission.k8s.io/v1`, the following additional validation is performed on their responses:...

a token with the given audience bound to the current pod and its service account. This KSA token along with required annotations on the KSA defined in configuration will be sent to the credential provider plugin via its standard input (along with the image information that is already sent today). The KSA annotations to be sent are configurable in the kubelet credential provider configuration.

 * ### Fragment
 *
 * The fragment is optional: it can be null, empty, or non-empty. Unlike host, port, path, and
 * query the fragment is not sent to the webserver: it's private to the client.

 * ## Encoding
 *
 * Each component must be encoded before it is embedded in the complete URL. As we saw above, the
