- **Cluster Federation**
  - Global Multi-cluster HTTP(S) Ingress across GCE and GKE clusters.
  - Expanded support for federated hybrid-cloud resources including ReplicaSets, Secrets, Namespaces and Events.
- **Security**
  - Increased pod-level security granularity (eg: Container Image Policies, AppArmor and `sysctl` support)
  - Increased cluster-level security granularity (eg: Access Review API)

- **Cluster Lifecycle**
  - [alpha] Improved UX and usability for the kubeadm binary that makes it easy to get a new cluster running. ([docs](http://kubernetes.io/docs/getting-started-guides/kubeadm/)) ([changelog](https://github.com/kubernetes/kubeadm/blob/master/CHANGELOG.md)) ([kubernetes/features#11](https://github.com/kubernetes/enhancements/issues/11))
- **Cluster Ops**

- `kube-proxy` nftables mode is now compatible with kernel `5.4`. ([#122296](https://github.com/kubernetes/kubernetes/pull/122296), [@tnqn](https://github.com/tnqn))
- Renamed Label cluster to `storage_cluster_id` for `apiserver_storage_size_bytes metric` ([#124283](https://github.com/kubernetes/kubernetes/pull/124283), [dims](https://github.com/dims))

  Last came a little feeble, squeaking voice, (`That's Bill,'
thought Alice,) `Well, I hardly know--No more, thank ye; I'm
better now--but I'm a deal too flustered to tell you--all I know
is, something comes at me like a Jack-in-the-box, and up I goes

  `So you did, old fellow!' said the others.
