* kubelets that specify `--cloud-provider` now only report addresses in Node status as determined by the cloud provider ([#65594](https://github.com/kubernetes/kubernetes/pull/65594), [@liggitt](https://github.com/liggitt))
   * kubelet serving certificate rotation now reacts to changes in reported node addresses, and will request certificates for addresses set by an external cloud provider

regression that could incorrectly reject pods with `OutOfCpu` errors if they were rapidly scheduled after other pods were reported as complete in the API. The Kubelet now waits to report the phase of a pod as terminal in the API until all running containers are guaranteed to have stopped and no new containers can be started.  Short-lived pods may take slightly longer (~1s) to report Succeeded or Failed after this change. ([#108366](https://github.com/kubernetes/kubernetes/pull/108366), [@smarterclay...
