- `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))

* kubeadm will pull required images during preflight checks if it cannot find them on the system ([#64105](https://github.com/kubernetes/kubernetes/pull/64105), [@chuckha](https://github.com/chuckha))
* kubeadm: rename the addon parameter `kube-dns` to `coredns` for `kubeadm alpha phases addons` as CoreDNS is now the default DNS server in 1.11. ([#64274](https://github.com/kubernetes/kubernetes/pull/64274), [@neolit123](https://github.com/neolit123))
