## Changes by Kind

### API Change

- Aggregated discovery now returns `responseKind: {}` for resources which are missing group/version/kind information, to ensure compatibility with v0.26.0-v0.26.3 clients. ([#119835](https://github.com/kubernetes/kubernetes/pull/119835), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

### Feature

### Failing Test

- Backport: e2e.test now uses the secure port to retrieve metrics data to ensure compatibility with 1.21 and 1.22 (for upgrade tests) (#104328, @pohly) [SIG API Machinery, Instrumentation, Storage and Testing]

### Bug or Regression

- Aggregate errors when putting vmss

- Disable watchcache for events.k8.io/Event resource for compatibility with core/Event. ([#96117](https://github.com/kubernetes/kubernetes/pull/96117), [@wojtek-t](https://github.com/wojtek-t)) [SIG Scalability]

* BUG FIX: Check both name and ports for azure health probes ([#56918](https://github.com/kubernetes/kubernetes/pull/56918), [@feiskyer](https://github.com/feiskyer))
* Provides compatibility of fields SizeLimit in types.EmptyDirVolumeSource since v1.7.8 ([#56505](https://github.com/kubernetes/kubernetes/pull/56505), [@yue9944882](https://github.com/yue9944882))

  
  Having appropriate QueueingHintFn contributes to reducing useless retries and thus improves the overall scheduler's performance.
  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

- Added alpha metrics for compatibility versioning ([#131842](https://github.com/kubernetes/kubernetes/pull/131842), [@michaelasp](https://github.com/michaelasp)) [SIG API Machinery, Architecture, Instrumentation and Scheduling]

  The `flowcontrol.apiserver.k8s.io/v1beta3` APIs are deprecated and will no longer be served in v1.32. All existing objects are available...

### Windows containerd support graduates to beta

Initially introduced in Kubernetes 1.18, Windows containerd support goes to Beta on this release. This includes the added support for Windows Server version 2004 (complete version compatibility can be found in the [documentation for Windows](https://kubernetes.io/docs/setup/production-environment/windows/intro-windows-in-kubernetes/#cri-containerd)).

SIG Windows is also including several addition to this release:
