* Fixed kube-proxy to work correctly with iptables 1.6.2 and later. ([#61734](https://github.com/kubernetes/kubernetes/pull/61734), [@danwinship](https://github.com/danwinship))
* Ensure cloudprovider.InstanceNotFound is reported when the VM is not found on Azure ([#61531](https://github.com/kubernetes/kubernetes/pull/61531), [@feiskyer](https://github.com/feiskyer))

- Number of errors reported to the metric `storage_operation_duration_seconds_count` for emptyDir decreased significantly because previously one error was reported for each projected volume created. ([#117022](https://github.com/kubernetes/kubernetes/pull/117022), [@mpatlasov](https://github.com/mpatlasov)) [SIG Storage]

 - Scheduling failures due to no nodes available are now reported as unschedulable under ```schedule_attempts_total``` metric. ([#90989](https://github.com/kubernetes/kubernetes/pull/90989), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling]

### Other (Cleanup or Flake)

* Fixes an issue with kubelet-reported pod status on deleted/recreated pods. ([#86320](https://github.com/kubernetes/kubernetes/pull/86320), [@liggitt](https://github.com/liggitt))

	// If content is very large, an alternative to setting Content or File
	// is to set Size, which will then be checked against the header-reported size
	// but will bypass the decompressing of the actual data.
	// This last option is used for testing very large (multi-GB) compressed files.

* Kubelet will now 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...
