- consumers of the 'certificatesigningrequests/approval' API must now have permission to 'approve' CSRs for the specific signer requested by the CSR. More information on the new signerName field and the required authorization can be found at https://kubernetes.io/docs/reference/access-authn-authz/certificate-signing-requests#authorization ([#88246](https://github.com/kubernetes/ku...

### Bug or Regression

- Fix nil pointer panic in BuildOpenAPIV2 and BuildOpenAPIV3 utilities, used by kube-apiserver's openAPI controller, when a CRD is missing version the requested version. ([#128940](https://github.com/kubernetes/kubernetes/pull/128940), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

### Other (Cleanup or Flake)

- Fixes an issue where the vsphere cloud provider will not trust a certificate if:
  - The issuer of the certificate is unknown (x509.UnknownAuthorityError)
  - The requested name does not match the set of authorized names (x509.HostnameError)

  - `kube-apiserver` publishes `apiserver_requested_deprecated_apis` gauge metrics set to `1` for deprecated APIs which have been requested, with `group`, `version`, `resource`, `subresource`, and `removed_release` labels ([#73032](https://github.com/kubernetes/kubernetes/pull/73032), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Instrumentation and Testing]
