  This is currently an alpha-level feature and while it probably will not
  eat your data, it may nibble at it a bit. (It passes e2e testing but has
  not yet seen real-world use.)
  
  At this point it should be functionally mostly identical to the iptables
  mode, except that it does not (and will not) support Service NodePorts on

  1. `apiGroup`: If set, it must be a valid DNS subdomain (e.g. 'example.com').
  2. `kind` and `name`: It must be valid path segment name. It may not be '.' or '..' and it may not contain '/' and '%' characters. ([#125218](https://github.com/kubernetes/kubernetes/pull/125218), [@carlory](https://github.com/carlory))

- Kubeadm: remove 'kubeadm upgrade node config' command since it was deprecated in v1.15, please use 'kubeadm upgrade node phase kubelet-config' instead ([#87975](https://github.com/kubernetes/kubernetes/pull/87975), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

* Default mount propagation has changed from `HostToContainer` ("rslave" in Linux terminology), as it was in 1.10, to `None` ("private") to match the behavior in 1.9 and earlier releases; `HostToContainer` as a default caused regressions in some pods. If you are relying on this behavior you will need to set it explicitly. ([#62462](https://github.com/kubernetes/kubernetes/pull/62462), [@jsafrane](https://github.com/jsafrane))

- Kubeadm no longer removes /etc/cni/net.d as it does not install it. Users should remove files from it manually or rely on the component that created them ([#83950](https://github.com/kubernetes/kubernetes/pull/83950), [@yastij](https://github.com/yastij))

* StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting StatefulSet Pod management is now ignored. If you were setting it to `true` or leaving it unset, no action is required. However, if you were setting it to `false`, be aware that previously-dormant StatefulSets may become active after upgrading.
