* Alpha annotation for PersistentVolume node affinity has been removed.  Update your PersistentVolumes to use the beta PersistentVolume.nodeAffinity field before upgrading to this release. ([#61816](https://github.com/kubernetes/kubernetes/pull/61816), [@wackxu
](https://github.com/wackxu))

#### Removed Deprecations

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.

  Don't use these flags. Using deprecated flags causes the kubelet to print a warning. Using a removed flag causes the kubelet to abort the startup.

## Action Required

- etcd2 as a backend is deprecated and support will be removed in Kubernetes 1.13.

- kubectl
  - `kubectl convert`, deprecated since v1.14, will be removed in v1.17.
  - The `--export` flag for the `kubectl get` command, deprecated since v1.14, will be removed in v1.18.
  - The `--pod`/`-p` flag for `kubectl exec`, deprecated since 1.12, has been removed.

### kubeadm
* Quite a few flags been renamed or removed.  Those options that are removed as flags can still be accessed via the config file.  Most notably this includes external etcd settings and the option for setting the cloud provider on the API server.  The [kubeadm reference documentation](https://kubernetes.io/docs/admin/kubeadm/) is up to date with the new flags.

### Other Deprecations

- Removed the recently re-introduced schedulability predicate ([#109706](https://github.com/kubernetes/kubernetes/pull/109706)) as to not have unschedulable nodes removed from load balancers back-end pools. ([#111691](https://github.com/kubernetes/kubernetes/pull/111691), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu))
