- Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. ([#92118](https://github.com/kubernetes/kubernetes/pull/92118), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

* Kubelet will set extended resource capacity to zero after it restarts. If the extended resource is exported by a device plugin, its capacity will change to a valid value after the device plugin re-connects with the Kubelet. If the extended resource is exported by an external component through direct node status capacity patching, the component should repatch the field after kubelet becomes ready again. During the time gap, pods previously assigned...

* Nodes are not deleted from kubernetes anymore if node is shutdown in Openstack. ([#59931](https://github.com/kubernetes/kubernetes/pull/59931), [@zetaab](https://github.com/zetaab))
* Re-enabled nodeipam controller for external clouds. Re-enables nodeipam controller for external clouds. Also does a small refactor so that we don't need to pass in allocateNodeCidr into the controller.

you do this, then, at the time you re-vendor the "<code>k8s.io/kubernetes/"</code> code, you will need to set <code>job.Spec.ManualSelector = true</code>, or else set <code>job.Spec.Selector = nil.  </code>Otherwise, the jobs you create may be rejected.  See [Specifying your own pod se...

### Bug or Regression

  * The `--failure-domains` scheduler command line-argument is not supported in the beta version of the feature.

* **Taints**
  * You will need to use `kubectl taint` to re-create all of your taints after kubectl and the master are upgraded to 1.6. Between the time the master is upgraded to 1.6 and when you do this, your existing taints will have no effect.

### Bug or Regression

- Terminated Pods on a node will not be re-admitted on kubelet restart. This fixes the problem of Completed Pods awaiting for the finalizer marked as Failed after the kubelet restart.
