- Kubeadm now prints all the kubelets and nodes that need to be upgraded when running "upgrade plan".
   ([#123578](https://github.com/kubernetes/kubernetes/pull/123578), [@carlory](https://github.com/carlory))

### (No, really, you MUST read this before you upgrade)

- [Namespaced Brokers](https://svc-cat.io/docs/namespaced-broker-resources/), which enable operators to install a broker into a namespace instead of the cluster level, reached GA.
- The [Service Plan Defaults](https://svc-cat.io/docs/service-plan-defaults/) feature is in alpha and is under active development. This feature gives operators the ability to define defaults for when someone provisions a service.

- Support `controlplane` as a valid EgressSelection type in the EgressSelectorConfiguration...

Kubernetes 1.8 adds the apps/v1beta2 group and version, which now consists of the
DaemonSet, Deployment, ReplicaSet and StatefulSet kinds. This group and version are part
of the Kubernetes Workloads API. We plan to move them to v1 in an upcoming release, so you might want to plan your migration accordingly.

For more information, see [the issue that describes this work in detail](https://github.com/kubernetes/enhancements/issues/353)

- kubeadm: `kubeadm upgrade plan` now supports `--etcd-upgrade` flag to control whether the etcd upgrade plan should be displayed. Add an `EtcdUpgrade` field into `UpgradeConfiguration.Plan` for v1beta4. ([#130023](https://github.com/kubernetes/kubernetes/pull/130023), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- New metric `kubelet_pleg_last_seen_seconds` to aid diagnosis of PLEG not healthy issues. ([#86251](https://github.com/kubernetes/kubernetes/pull/86251), [@bboreham](https://github.com/bboreham)) [SIG Node]

### Other (Bug, Cleanup or Flake)

*   kube-apiserver: `--ssh-user` and `--ssh-keyfile` are now deprecated and will be removed in a future release. Users of SSH tunnel functionality in Google Container Engine for the Master -> Cluster communication should plan alternate methods for bridging master and node networks.
