### Kubernetes Node system swap support

* Makes the kube-dns addon optional so that users can deploy their own DNS solution. ([#57113](https://github.com/kubernetes/kubernetes/pull/57113), [@wwwtyro](https://github.com/wwwtyro))

## Known Issues

### Summary API in kubelet doesn't have accelerator metrics

* Remove extensions/v1beta1 Jobs resource, and job/v1beta1 generator. ([#38614](https://github.com/kubernetes/kubernetes/pull/38614), [@soltysh](https://github.com/soltysh))
