* 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))

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). ...

- Added support for CEL(Common Expression Language) expressions and `additionalProperties` to be used under nested quantifiers in CRD schemas. ([#124381](https://github.com/kubernetes/kubernetes/pull/124381), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]
- Added support for building Windows kube-proxy container image.

A security issue was discovered in Kubernetes where users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can to modify Node objects and send requests proxying through them.

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint.

- 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))
