 - Newly provisioned PVs by gce-pd will no longer have the beta FailureDomain label. gce-pd volume plugin will start to have GA topology label instead.

If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent. However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version. That meant the new object was not matched by the filter. This was a regression from behavior between cached watches on the server side and uncached watches, and...

- Scheduler no longer runs the plugin's `Filter` method when its `PreFilter` method returned a Skip status.

* Make volume usage metrics available for Cinder ([#62668](https://github.com/kubernetes/kubernetes/pull/62668), [@zetaab](https://github.com/zetaab))

    *   Federation-specific behavior will no longer be included in kubectl
    *   kubefed will no longer be released as part of Kubernetes

### **Node**

  when the corresponding csi driver was installed:
  - `awsElasticBlockStore` for `ebs.csi.aws.com`
  - `azureDisk` for `disk.csi.azure.com`
  - `gcePersistentDisk` for `pd.csi.storage.googleapis.com`
  - `cinder` for `cinder.csi.openstack.org`
  - `csi`
  However it was still enforced using a limit in CSINode objects. ([#126924](https://github.com/kubernetes/kubernetes/pull/126924), [@carlory](https://github.com/carlory))

- Add support for CSI spec v0.3.0 for both Cinder and Manilla
- Add 'cascade delete' support for Octavia load balancers to improve performance.
- Add improved load balancer naming.
