- Volume attach or publish operation will not fail at `kubelet` if target path directory already exists on the node. ([#119735](https://github.com/kubernetes/kubernetes/pull/119735), [@akankshapanse](https://github.com/akankshapanse))

## Known Issues for v1.6.3

* This release introduced a regression when using [subPath](https://kubernetes.io/docs/concepts/storage/volumes/#using-subpath).
  If the `subPath` is a file rather than a directory, Pods may fail to start ([#45613](https://github.com/kubernetes/kubernetes/issues/45613)).

  **Do not upgrade to v1.6.3** if your cluster may run Pods with such subPaths.
