### Node

### CLI

This release includes a change to [kubectl get and describe to work better with extensions](https://github.com/kubernetes/enhancements/issues/515), as the server, rather than the client, returns this information for a smoother user experience.

  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 
  But, registering appropriate `QueueingHintFn` is, of course, better from a scheduling performance perspective. ([#118551](https://github.com/kubernetes/kubernetes/pull/118551), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling, Storage and Testing]

    * Action required:
    * Anyone who generated server cert for admission webhooks need to regenerate the cert. Previously, when generating server cert for the admission webhook, the CN value doesn't matter. Now you must set it to the DNS name of the webhook service, i.e., `<service.Name>.<service.Namespace>.svc`.

### API Change

#### New API types/versions:
- A new IngressClass resource has been added to enable better Ingress configuration. ([#88509](https://github.com/kubernetes/kubernetes/pull/88509), [@robscott](https://github.com/robscott)) [SIG API Machinery, Apps, CLI, Network, Node and Testing]
