### Network

- Ingress objects are now persisted in etcd using the networking.k8s.io/v1beta1 version ([#77139](https://github.com/kubernetes/kubernetes/pull/77139), [@cmluciano](https://github.com/cmluciano))
- Transparent kube-proxy restarts when using IPVS are now allowed. ([#75283](https://github.com/kubernetes/kubernetes/pull/75283), [@lbernail](https://github.com/lbernail))

- **Overhauled metrics**: Kubernetes has previously made extensive use of a global metrics registry to register metrics to be exposed. By implementing a metrics registry, metrics are registered in more transparent means. Previously, Kubernetes metrics have been excluded from any kind of stability requirements.

* Node-Problem-Detector configuration is now decoupled from the Kubernetes release on GKE/GCE. ([#73288](https://github.com/kubernetes/kubernetes/pull/73288), [@wangzhen127](https://github.com/wangzhen127))
* [IPVS] Allow for transparent kube-proxy restarts ([#75283](https://github.com/kubernetes/kubernetes/pull/75283), [@lbernail](https://github.com/lbernail))

- Previously, the pod name and namespace were eliminated in the event log message. This PR attempts to add the preemptor pod UID in the preemption event message logs for easier debugging and safer transparency.
