* Fixed an issue where Portworx volume driver wasn't passing namespace and annotations to the Portworx Create API. ([#59607](https://github.com/kubernetes/kubernetes/pull/59607), [@harsh-px](https://github.com/harsh-px))

* [alpha] Improve Flex volume deployment

  * Flex volume driver deployment is simplified in the following ways:

    * New driver files can now be automatically discovered and initialized without requiring a kubelet or controller-manager restart.

    * A sample DaemonSet to deploy Flexvolume drivers is now available.

Nevertheless, as this would mean waiting for the response to travel through the network while unnecessarily holding a resource in a dependency with yield (for example a database connection), this was changed in FastAPI 0.106.0.

    * Docker version 1.12.6 known issues

        * overlay2 driver not fully supported

        * live-restore not fully supported

        * no shared pid namespace support

    * Docker version 1.11.2 known issues

- Unlocked the `CSIMigrationvSphere` feature gate.
