### Instrumentation

In v1.9 we focused on improving stability of the components owned by the SIG, including Heapster, Custom Metrics API adapters for Prometheus, and Stackdriver.

- Added a new controller, volumeattributesclass-protection-controller, into the kube-controller-manager.
  The new controller manages a protective finalizer on VolumeAttributesClass objects. ([#123549](https://github.com/kubernetes/kubernetes/pull/123549), [@carlory](https://github.com/carlory)) [SIG API Machinery, Apps, Auth and Storage]

now always set to "systemd" unless the user is explicit about it. This requires existing machine setups to configure the container runtime to use the "systemd" driver. Documentation on this topic can be found here: https://kubernetes.io/docs/setup/production-environment/container-runtimes/. When upgrading existing clusters / nodes using "kubeadm upgrade" the old cgroupDriver value is preserved, but in 1.22 this change will also apply to "upgrade". For more information on migrating to the "systemd" driver...

  purposes, you can use older kernels, as far back as 5.4, if you set the
  `nftables.skipKernelVersionCheck` option in the kube-proxy config, but this is not
  recommended in production since it may cause problems with other nftables
  users on the system.) ([#124152](https://github.com/kubernetes/kubernetes/pull/124152), [@danwinship](https://github.com/danwinship)) [SIG Network]

CSI was first introduction as alpha in Kubernetes v1.9 and moved to beta in Kubernetes v1.10.

You can find a list of sample and production drivers in the [CSI Documentation](https://kubernetes.io/docs/concepts/storage/volumes/#csi).

* ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/drivers.html were inspected and should not be impacted after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ([#65499]...

## **Major Themes**

Kubernetes 1.7 is a milestone release that adds security, stateful application, and extensibility features motivated by widespread production use of Kubernetes.

 *   Added utility `tf.keras.utils.FeatureSpace`, a one-stop shop for structured data preprocessing and encoding.
