- If `kubeadm reset` finds no etcd member ID for the peer it removes during the `remove-etcd-member` phase, it continues immediately to other phases, instead of retrying the phase for up to 3 minutes before continuing.

- Feat: support [Azure shared disk](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disks-shared-enable), added a new field(`maxShares`) in azure disk storage class:
  
  - kind: StorageClass
  - apiVersion: storage.k8s.io/v1
  - metadata:
    - name: shared-disk
  - provisioner: kubernetes.io/azure-disk
  - parameters:

	mrfReplicaCh    chan ReplicationWorkerOperation
	mrfSaveCh       chan MRFReplicateEntry
	mrfStopCh       chan struct{}
	mrfWorkerSize   int
}

// ReplicationWorkerOperation is a shared interface of replication operations.
type ReplicationWorkerOperation interface {
	ToMRFEntry() MRFReplicateEntry
}

const (
	// WorkerMaxLimit max number of workers per node for "fast" mode

- Fixed a race condition between `Run()` and `SetTransform()` and `SetWatchErrorHandler()` in shared informers. ([#117870](https://github.com/kubernetes/kubernetes/pull/117870), [@howardjohn](https://github.com/howardjohn)) [SIG API Machinery]

  * OOM parser uses kmsg
  * Add hugepages support
  * Add CRI-O support

* Sharing a PID namespace between containers in a pod is disabled by default in version 1.8. To enable for a node, use the `--docker-disable-shared-pid=false` kubelet flag. Be aware that PID namespace sharing requires Docker version greater than or equal to 1.13.1.

* Fix issues related to the eviction manager.

* Fix inconsistent Prometheus cAdvisor metrics.

endpoint for the kubelet when creating a cluster with "kubeadm init" or when joining control plane nodes with "kubeadm join".  The "kubeadm join" workflow now includes two new experimental phases called "control-plane-join-etcd" and "kubelet-wait-bootstrap" which will be used when the feature gate is enabled. This phases will be marked as non-experimental when ControlPlaneKubeletLocalMode becomes GA. During "kubeadm upgrade" commands, if the feature gate is enabled, modify the "/etc/kubernetes/kubelet.conf...
