9.4.0
^^^^^


New Features
************

* The default 10 seconds health polling interval is too frequent for
  most of the cases. Now it has been changed to 60s. A new config
  *health_polling_interval* is supported to make the interval
  configurable. Cloud admin can totally disable the health polling by
  set a negative value for the config.

* New labels to support containerd as a runtime.

  container_runtime The container runtime to use. Empty value means,
  use docker from the host. Since ussuri, apart from empty (host-
  docker), containerd is also an option.

  containerd_version The containerd version to use as released in
  https://github.com/containerd/containerd/releases and
  https://storage.googleapis.com/cri-containerd-release/

  containerd_tarball_url Url with the tarball of containerd's
  binaries.

  containerd_tarball_sha256 sha256 of the tarball fetched with
  containerd_tarball_url or from https://storage.googleapis.com/cri-
  containerd-release/.


Upgrade Notes
*************

* If it's still preferred to have 10s health polling interval for
  Kubernetes cluster. It can be set by config
  *health_polling_interval* under *kubernetes* section.


Bug Fixes
*********

* Fix an issue with private clusters getting stuck in
  CREATE_IN_PROGRESS status where floating_ip_enabled=True in the
  cluster template but this is disabled when the cluster is created.

* The taint of master node kubelet has been improved to get the
  conformance test (sonobuoy) passed.

* For fcos-kubelet, add rpc-statd dependency. To mount nfs volumes
  with the embedded volume pkg [0], rpc-statd is required and should
  be started by mount.nfs. When running kubelet in a chroot this
  fails. With atomic containers it used to work. [0]
