- OpenAPI V2 will no longer publish aggregated API server OpenAPI for group versions that do not match the APIService specified group version. ([#123570](https://github.com/kubernetes/kubernetes/pull/123570), [@Jefftree](https://github.com/Jefftree))

  Yes, discovery document will correctly return the resources for aggregated apiservers that do not implement aggregated disovery ([#115805](https://github.com/kubernetes/kubernetes/pull/115805), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]

certificates used by admission webhooks, custom resource conversion webhooks, and aggregated API servers must now include valid Subject Alternative Names. If you are running Kubernetes 1.22 with `GODEBUG=x509ignoreCN=0` set, check the `apiserver_kube_aggregator_x509_missing_san_total` and `apiserver_webhooks_x509_missing_san_total` metrics for non-zero values to see if the API server is connecting to webhooks or aggregated API servers using certificates that will be considered invalid in Kubernetes 1.23+....
