- Improve speed of vSphere PV provisioning and reduce number of API calls ([#102351](https://github.com/kubernetes/kubernetes/pull/102351), [@gnufied](https://github.com/gnufied)) [SIG Cloud Provider and Storage]
- Register/Deregister Targets in chunks for AWS TargetGroup ([#101592](https://github.com/kubernetes/kubernetes/pull/101592), [@M00nF1sh](https://github.com/M00nF1sh)) [SIG Cloud Provider]

  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

* Refactor kube-proxy configuration ([#34727](https://github.com/kubernetes/kubernetes/pull/34727), [@ncdc](https://github.com/ncdc))

### Other notable changes

* kubeadm: Fix invalid assign statement so it is possible to register the master kubelet with other initial Taints ([#45376](https://github.com/kubernetes/kubernetes/pull/45376), [@luxas](https://github.com/luxas))

For more information, see [#51899](https://github.com/kubernetes/kubernetes/issues/51899).

* Minikube version 0.22.2 or lower does not work with kubectl version 1.8 or higher. This issue is caused by the presence of an unregistered type in the minikube API server. New versions of kubectl force validate the OpenAPI schema, which is not registered with all known types in the minikube API server.

*   Added Windows support to the system verification check. ([#53730](https://github.com/kubernetes/kubernetes/pull/53730),[ @bsteciuk](https://github.com/bsteciuk))

* Openstack: register metadata.hostname as node name ([#58502](https://github.com/kubernetes/kubernetes/pull/58502), [@dixudx](https://github.com/dixudx))

- Fixed an issue in register-gen where imports for k8s.io/apimachinery/pkg/runtime and k8s.io/apimachinery/pkg/runtime/schema were missing. ([#130392](https://github.com/kubernetes/kubernetes/pull/130392), [@mrIncompetent](https://github.com/mrIncompetent)) [SIG API Machinery]...

- **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.

  It's definitely not something expected for plugin developers,
  and we're trying to eventually remove preCheck completely to fix this.
  Until then we'll register UpdateNodeTaint event for plugins that have NodeAdded event, but don't have UpdateNodeTaint event.
  It'd result in a bad impact on the requeuing efficiency though, a lot better than some Pods being stuck in the
