* Clean up items from moving local cluster setup guides ([#30035](https://github.com/kubernetes/kubernetes/pull/30035), [@pwittrock](https://github.com/pwittrock))

- The `ClusterTrustBundle` API is moving to `v1beta1`.

* Increase allowed lag for ssh key sync loop in tunneler to allow for one failure ([#60068](https://github.com/kubernetes/kubernetes/pull/60068), [@wojtek-t](https://github.com/wojtek-t))
* Fixing a bug in OpenStack cloud provider, where dual stack deployments (IPv4 and IPv6) did not work well when using kubenet as the network plugin. ([#59749](https://github.com/kubernetes/kubernetes/pull/59749), [@zioproto](https://github.com/zioproto))

    * DualStack:
    * => IPv4 BackendPool name == clusterName
    * => IPv6 BackendPool name == <clusterName>-IPv6
    * This result into:
    * - clusters moving from IPv4 to duakstack will require no changes
    * - clusters moving from IPv6 (while not seen in the wild, we can not rule out their existence) to dualstack will require deleting backend pools (the reconciler will take care of creating correct backendpools)

- Fixed bug that caused cAdvisor to incorrectly detect single-socket multi-NUMA topology. ([#99207](https://github.com/kubernetes/kubernetes/pull/99207), [@iwankgb](https://github.com/iwankgb)) [SIG Node]

	* Support running Ubuntu image on GCE node ([#44744](https://github.com/kubernetes/kubernetes/pull/44744), [@yguo0905](https://github.com/yguo0905))

  * The gce metadata server can now be hidden behind a proxy, hiding the kubelet's token. ([#45565](https://github.com/kubernetes/kubernetes/pull/45565), [@Q-Lee](https://github.com/Q-Lee))
