- `kube-apiserver` added:
  - `alpha` support (guarded by the `ServiceAccountTokenJTI` feature gate) for adding a `jti` (JWT ID) claim to service account tokens it issues, adding an `authentication.kubernetes.io/credential-id` audit annotation in audit logs when the tokens are issued, and `authentication.kubernetes.io/credential-id` entry in the extra user info when the token is used to authenticate.

- X.509 client certificate authentication to kube-apiserver now produces credential IDs (derived from the certificate's signature) for use by audit logging.

- Added `auditAnnotations` to `ValidatingAdmissionPolicy`, enabling CEL to be used to add audit annotations to request audit events.
  Added `validationActions` to `ValidatingAdmissionPolicyBinding`, enabling validation failures to be handled by any combination of the warn, audit and deny enforcement actions. ([#115973](https://github.com/kubernetes/kubernetes/pull/115973), [@jpbetz](https://github.com/jpbetz))

- The EndpointSlice controller now waits for EndpointSlice and Node caches to be synced before starting. ([#94086](https://github.com/kubernetes/kubernetes/pull/94086), [@robscott](https://github.com/robscott)) [SIG Apps and Network]
- The audit event sourceIPs list will now always end with the IP that sent the request directly to the API server. ([#87167](https://github.com/kubernetes/kubernetes/pull/87167), [@tallclair](https://github.com/tallclair)) [SIG API Machinery and Auth]

- Updated an audit annotation key used by the `…/serviceaccounts/<name>/token` resource handler.
