### Additional Notable Feature Updates

  Ginkgo V2 doesn't accept go test's `-parallel` flags to parallelize Ginkgo specs, please switch to use `ginkgo -p` or `ginkgo -procs=N` instead.

- `volumes`: `resource.claims` is now cleared for PVC specs during create or update of a pod spec with inline PVC template or of a PVC because it has no effect. ([#115928](https://github.com/kubernetes/kubernetes/pull/115928), [@pohly](https://github.com/pohly))

### API Change

- Volumes: `resource.claims` gets cleared for PVC specs during create or update of a pod spec with inline PVC template or of a PVC because it has no effect. ([#115928](https://github.com/kubernetes/kubernetes/pull/115928), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps and Storage]

- kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version.
- kubeadm now automatically sets the `--pod-infra-container-image` flag when starting the kubelet.

### SIG IBM Cloud

  The scheduling hints allow the scheduler to only retry scheduling a `Pod`
  that was previously rejected by the `NodeSchedulable` plugin if a new `Node` or a `Node` update sets `.spec.unschedulable` to false. ([#119396](https://github.com/kubernetes/kubernetes/pull/119396), [@wackxu](https://github.com/wackxu))
- `kube-scheduler` implements scheduling hints for the `NodeAffinity` plugin.
