Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack code, the SIG largely focused on bug fixes and updates to match K8s 1.13 development.

### SIG Scalability

  - Add missing stable labels to template nodes
  
  ### HuaweiCloud
  - Add auto scaling group support
  - Implement node group by AS
  - Implement getting desired instance number of node group
  - Implement increasing node group size
  - Implement TemplateNodeInfo
  - Implement caching instances
  
  ### IONOS
  - Add support for IONOS
  
  ### Kubemark

		srcBuf.Reset()
		src.Reset(srcBuf)
		dstBuf.Reset()
		io.Copy(dst, src)
	}
}

func BenchmarkReaderCopyUnoptimal(b *testing.B) {
	// Unoptimal case is where the underlying reader doesn't implement io.WriterTo
	srcBuf := bytes.NewBuffer(make([]byte, 8192))
	src := NewReader(onlyReader{srcBuf})
	dstBuf := new(bytes.Buffer)
	dst := onlyWriter{dstBuf}
	for i := 0; i < b.N; i++ {
		srcBuf.Reset()

   ([#123190](https://github.com/kubernetes/kubernetes/pull/123190), [@padlar](https://github.com/padlar))
- Allowed scheduling framework plugins that implement `io.Closer` to be gracefully closed.
   ([#122498](https://github.com/kubernetes/kubernetes/pull/122498), [@Gekko0114](https://github.com/Gekko0114))
- Bumped cAdvisor to `v0.49.0`.

# Release 2.17.1

### Bug Fixes and Other Changes

* Add necessary header files in the aar library. These are needed if developers build apps with header files unpacked from tflite aar files from maven.
* Implement Name() for GCSWritableFile to fix the profiler trace viewer cache file generation.
* Fix `cstring.h` missing file issue with the Libtensorflow archive.

# Release 2.17.0

## TensorFlow

### Breaking Changes

   * MultimapBuilder} does not support.
   *
   * <p><b>Warning: do not use</b> this method when the collections returned by {@code factory}
   * implement either {@link List} or {@code Set}! Use the more specific method {@link
   * #newListMultimap}, {@link #newSetMultimap} or {@link #newSortedSetMultimap} instead, to avoid
   * very surprising behavior from {@link Multimap#equals}.

Maintainers of FlexVolume drivers should implement a CSI driver and move users of FlexVolume to CSI.
Users of FlexVolume should move their workloads to CSI driver.

### Deprecation of klog specific flags

- Fix race in alpha aggregated discovery handler
  Yes, discovery document will correctly return the resources for aggregated apiservers that do not implement aggregated disovery ([#115805](https://github.com/kubernetes/kubernetes/pull/115805), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]

- Kube-proxy: added `--logging-format` flag to support structured logging. ([#117800](https://github.com/kubernetes/kubernetes/pull/117800), [@cyclinder](https://github.com/cyclinder))
- NodeVolumeLimits implement the `PreFilter` extension point for skipping the Filter phase if the Pod doesn't use volumes with limits. ([#115398](https://github.com/kubernetes/kubernetes/pull/115398), [@tangwz](https://github.com/tangwz)) [SIG Scheduling]
