- Add scheduling support for RuntimeClasses. RuntimeClasses can now specify nodeSelector constraints & tolerations, which are merged into the PodSpec for pods using that RuntimeClass. ([#80825](https://github.com/kubernetes/kubernetes/pull/80825), [@tallclair](https://github.com/tallclair))

*   Updated cluster printer to enable --show-labels ([#53771](https://github.com/kubernetes/kubernetes/pull/53771),[ @dixudx](https://github.com/dixudx))
*   Kubefed init now supports --nodeSelector, enabling you to determine on what node the controller will be installed. ([#50749](https://github.com/kubernetes/kubernetes/pull/50749),[ @dixudx](https://github.com/dixudx))

* Scheduler now has a summary-type metric, 'scheduling_latency_seconds'. ([#64838](https://github.com/kubernetes/kubernetes/pull/64838), [@krzysied](https://github.com/krzysied))
* `nodeSelector.matchFields` (node's `metadata.node`) is now supported in scheduler. ([#62453](https://github.com/kubernetes/kubernetes/pull/62453), [@k82cn](https://github.com/k82cn))

- Kubelet should reconcile `kubernetes.io/os` and `kubernetes.io/arch` labels on the node object. The side-effect of this is kubelet would deny admission to pod which has nodeSelector with label `kubernetes.io/os` or `kubernetes.io/arch` which doesn't match the underlying OS or arch on the host OS.
