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). ...

- 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 ([#93813](https://github.com/kubernetes/kubernetes/pull/93813), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider and Cluster Lifecycle]

- Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included).
