*   Best practice for version 1.9 and future versions is to explicitly set a cloud-provider. See [the documentation](https://kubernetes.io/docs/getting-started-guides/scratch/#cloud-providers)
*   The kubeadm `--skip-preflight-checks` flag is now deprecated and will be removed in a future release.

The flag determines whether pods in a terminal state are displayed. It will be inert in 1.11 and removed in a future release. ([#60210](https://github.com/kubernetes/kubernetes/pull/60210), [@deads2k](https://github.com/deads2k))

* The ability to use the insecure HTTP port of kube-controller-manager and cloud-controller-manager has been deprecated, and will be removed in a future release. Use `--secure-port` and `--bind-address` instead. ([#59582](https://github.com/kubernetes/kubernetes/pull/59582),...

- The CSI driver-registrar external sidecar container v1.0.0-rc2 is known to take up to 1 minute to start in some cases. We expect this issue to be resolved in a future release of the sidecar container. For verification, please see the release notes of future releases of the external sidecar container. ([#76](https://github.com/kubernetes-csi/driver-registrar/issues/76))

## Deprecations

### Kubernetes API Reference Documentation

- Marked the feature gate `ExperimentalHostUserNamespaceDefaulting` as deprecated.

- The `SecurityContextDeny` admission plugin is going deprecated and will be removed in future versions. ([#115879](https://github.com/kubernetes/kubernetes/pull/115879), [@mtardy](https://github.com/mtardy))

### API Change

- kubectl: `--use-openapi-print-columns` has been deprecated in favor of `--server-print`, and will be removed in a future version. ([#65601](https://github.com/kubernetes/kubernetes/pull/65601), [@liggitt](https://github.com/liggitt))...

* Created a new `dryRun` query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the `dryRun` query parameter. ([#63557](https://github.com/kubernetes/kubernetes/pull/63557), [@apelisse](https://github.com/apelisse))
