### Structured Logging in Kubelet

- kubeadm: JoinConfiguration now houses the discovery options in a nested Discovery structure, which in turn has a couple of other nested structures to house more specific options (BootstrapTokenDiscovery and FileDiscovery) ([#67763](https://github.com/kubernetes/kubernetes/pull/67763), [@rosti](https://github.com/rosti))

- Structured logging of NamespacedName was inconsistent with klog.KObj. Now both use lower case field names and namespace is optional. ([#117238](https://github.com/kubernetes/kubernetes/pull/117238), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture...

### CLI

* Use structured generator for kubectl autoscale.  ([#55913](https://github.com/kubernetes/kubernetes/pull/55913), [@wackxu](https://github.com/wackxu))

 ([#64792](https://github.com/kubernetes/kubernetes/pull/64792), [@luxas](https://github.com/luxas))

* NetworkPolicy has been moved from `extensions/v1beta1` to the new ([#39164](https://github.com/kubernetes/kubernetes/pull/39164), [@danwinship](https://github.com/danwinship))
	`networking.k8s.io/v1` API group. The structure remains unchanged from
	the beta1 API.
	The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
	to opt in to isolation has been removed. Instead, isolation is now

- Kubeadm: enhance certs check-expiration to show the expiration info of related CAs ([#83932](https://github.com/kubernetes/kubernetes/pull/83932), [@SataQiu](https://github.com/SataQiu))
- Kubeadm: implemented structured output of 'kubeadm token list' in JSON, YAML, Go template and JsonPath formats ([#78764](https://github.com/kubernetes/kubernetes/pull/78764), [@bart0sh](https://github.com/bart0sh))

- Kube-proxy: added `--logging-format` flag to support structured logging. ([#117800](https://github.com/kubernetes/kubernetes/pull/117800), [@cyclinder](https://github.com/cyclinder))

### Structured logging graduate to Beta

Structured logging reached its Beta milestone. Most log messages from kubelet and kube-scheduler have been converted. Users are encouraged to try out JSON output or parsing of the structured text format and provide feedback on possible solutions for the open issues, such as handling of multi-line strings in log values.
