- Watch will now support converting response objects into Table or PartialObjectMetadata forms. ([#71548](https://github.com/kubernetes/kubernetes/pull/71548), [@smarterclayton](https://github.com/smarterclayton))

- Restored `NumPDBViolations` info of nodes, when `HTTPExtender ProcessPreemption`. This info will be used in subsequent filtering steps - `pickOneNodeForPreemption` ([#105853](https://github.com/kubernetes/kubernetes/pull/105853), [@caden2016](https://github.com/caden2016))

- Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release ([#81792](https://github.com/kubernetes/kubernetes/pull/81792), [@j-griffith](https://github.com/j-griffith))
- Integrated volume limits for in-tree and CSI volumes into one scheduler predicate. ([#77595](https://github.com/kubernetes/kubernetes/pull/77595), [@bertinatto](https://github.com/bertinatto))

## Deprecations and Removals

- API

  - The schema for the alpha `CSINodeInfo` CRD has been split into `spec` and `status` fields, and new fields `status.available` and `status.volumePluginMechanism` added. Clusters using the previous alpha schema must delete and recreate the CRD using the new schema. ([#70515](https://github.com/kubernetes/kubernetes/pull/70515),...

- JSON log output is configurable and now supports writing info messages to stdout and error messages to stderr. Info messages can be buffered in memory. The default is to write both to stdout without buffering, as before. ([#104873](https://github.com/kubernetes/kubernetes/pull/104873), [@pohly](https://github.com/pohly))

## Changelog since v1.18.19

## Changes by Kind

### Bug or Regression

- Reverted the previous fix for portforward cleanup because it introduced a kubelet regression which can lead into segmentation faults. ([#102838](https://github.com/kubernetes/kubernetes/pull/102838), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Node]

### Other (Cleanup or Flake)

were [vulnerable to race conditions](https://github.com/kubernetes/kubernetes/pull/102344) leading to early shutdown, resource leaks, or long delays in actually completing pod shutdown. As a consequence of this change the Kubelet now correctly takes into account the resources of running and terminating pods when deciding to accept new pods, since terminating pods are still holding on to those resources. This stricter handling may surface to end users as pod rejections when creating pods that are scheduled...
