### Other (Cleanup or Flake)

- Reverted the previous fix for portforward cleanup because it introduced a kubelet regression which can lead into segmentation faults. ([#102587](https://github.com/kubernetes/kubernetes/pull/102587), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Node]

### Other (Cleanup or Flake)

* - fluentd-gcp runs with a dedicated fluentd-gcp service account ([#54175](https://github.com/kubernetes/kubernetes/pull/54175), [@tallclair](https://github.com/tallclair))
    * - Stop mounting the host certificates into fluentd's prometheus-to-sd container

  - 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),...

- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123108](https://github.com/kubernetes/kubernetes/pull/123108), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- the IP allocator in v1.17.0 can return errors such as `the cluster IP <ip> for service <service-name> is not within the service CIDR <cidr>; please recreate` in the logs of...

- 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

#### API Machinery
* The protobuf serialization of API objects has been updated to store maps in a predictable order to ensure that the representation of that object does not change when saved into etcd. This prevents the same object from being seen as being modified, even when no values have changed. ([#47701](https://github.com/kubernetes/kubernetes/pull/47701), [@smarterclayton](https://github.com/smarterclayton))

- 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))

- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123107](https://github.com/kubernetes/kubernetes/pull/123107), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
