image repository for CoreDNS kubeadm now will append the `coredns` image name instead of `coredns/coredns`, thus restoring the behaviour existing before the v1.21 release. Users who rely on nested folder for the coredns image should set the `clusterConfiguration.dns.imageRepository` value including the nested path name (e.g using `registry.company.xyz/coredns` will force kubeadm to use `registry.company.xyz/coredns/coredns` image). No action is needed if using the default registry (k8s.gcr.io). ...

// Takes in Erasure object layer, and the list of API end points to be tested/required, registers the API end points and returns the HTTP handler.
// Need isolated registration of API end points while writing unit tests for end points.
// All the API end points are registered only for the default case.

* Fix a bug affecting nested data volumes such as secret, configmap, etc. ([#57422](https://github.com/kubernetes/kubernetes/pull/57422), [@joelsmith](https://github.com/joelsmith))

* Federation control plane can be upgraded by updating the image
fields in the `Deployment` specs of the control plane components.
However, federation control plane upgrades were not tested in this
release [38537](https://github.com/kubernetes/kubernetes/issues/38537)

- Fixed a performance issue applying json patches to deeply nested objects ([#93811](https://github.com/kubernetes/kubernetes/pull/93811), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]

- NOTE ([#113749](https://github.com/kubernetes/kubernetes/pull/113749), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]
- Nested `MountPoints` are now grouped correctly on all cases. ([#112571](https://github.com/kubernetes/kubernetes/pull/112571), [@claudiubelu](https://github.com/claudiubelu))
