* Volume expansion is now considered Beta. ([#64288](https://github.com/kubernetes/kubernetes/pull/64288), [@gnufied](https://github.com/gnufied))

- The following feature gates for volume expansion GA features have now been removed and must no longer be referenced in `--feature-gates` flags: `ExpandCSIVolumes`, `ExpandInUsePersistentVolumes`, `ExpandPersistentVolumes` ([#113942](https://github.com/kubernetes/kubernetes/pull/113942), [@meng...

### Bug or Regression

- Do not expand volume on the node, if controller expansion is finished ([#132010](https://github.com/kubernetes/kubernetes/pull/132010), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Do not log error event when waiting for expansion on the kubelet ([#132099](https://github.com/kubernetes/kubernetes/pull/132099), [@gnufied](https://github.com/gnufied)) [SIG Storage]

### CLI

This release includes a change to [kubectl get and describe to work better with extensions](https://github.com/kubernetes/enhancements/issues/515), as the server, rather than the client, returns this information for a smoother user experience.

### Network

- Implement support for recovering from volume expansion failures ([#106154](https://github.com/kubernetes/kubernetes/pull/106154), [@gnufied](https://github.com/gnufied)) [SIG API Machinery, Apps and Storage]

### Bug or Regression

- Do not expand volume on the node, if controller expansion is finished ([#131987](https://github.com/kubernetes/kubernetes/pull/131987), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Do not log error event when waiting for expansion on the kubelet ([#132098](https://github.com/kubernetes/kubernetes/pull/132098), [@gnufied](https://github.com/gnufied)) [SIG Storage]

### Apps

- The `.spec.rollbackTo` field of the Deployment kind is deprecated in `extensions/v1beta1`.

- The `kubernetes.io/created-by` annotation is deprecated and will be removed in version 1.9.

      int oldCapacity = oldTable.length();
      if (oldCapacity >= MAXIMUM_CAPACITY) {
        return;
      }

       * Reclassify nodes in each list to new Map. Because we are using power-of-two expansion, the
       * elements from each bin must either stay at same index, or move with a power of two offset.
       * We eliminate unnecessary node creation by catching cases where old nodes can be reused

- Decrease the amount of time it takes to modify kubeconfig files with large amounts of contexts ([#67093](https://github.com/kubernetes/kubernetes/pull/67093), [@juanvallejo](https://github.com/juanvallejo))
- Make EBS volume expansion faster ([#66728](https://github.com/kubernetes/kubernetes/pull/66728), [@gnufied](https://github.com/gnufied))

### Bug or Regression

- Fix error when trying to expand a volume that does not require node expansion ([#123055](https://github.com/kubernetes/kubernetes/pull/123055), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]
