client.networkInterceptors().add(loggingInterceptor);
    ```

    **Warning:** Avoid `Level.HEADERS` and `Level.BODY` in production because
    they could leak passwords and other authentication credentials to insecure
    logs.

 *  **WebSocket API now uses `RequestBody` and `ResponseBody` for messages.**
    This is a backwards-incompatible API change.

 *  **The DNS service is now pluggable.** In some situations this may be useful

### Runtime log sanitation

Logs can now be configured to use runtime protection from leaking sensitive data. [Details for this experimental feature is available in documentation](https://docs.k8s.io/concepts/cluster-administration/system-logs/#log-sanitization).

	// Invalid request conditions:
	//
	//   Cannot have both forceStart and forceStop in the same
	//   request; If clientToken is provided, request can only be
	//   to continue receiving logs, so it cannot be start or
	//   stop;

* Add Simplified Chinese translation for kubectl ([#45573](https://github.com/kubernetes/kubernetes/pull/45573), [@shiywang](https://github.com/shiywang))

### **kubectl (CLI)**
* Features

  * `kubectl logs` supports specifying a container name when using label selectors ([#44282](https://github.com/kubernetes/kubernetes/pull/44282), [@derekwaynecarr](https://github.com/derekwaynecarr))

// sends audit logs for internal subsystem activity
func auditLogInternal(ctx context.Context, opts AuditLogOptions) {
	if len(logger.AuditTargets()) == 0 {
		return
	}

	entry := audit.NewEntry(globalDeploymentID())

* Advanced audit policy now supports matching subresources and resource names, but the top level resource no longer matches the subresouce. For example "pods" no longer matches requests to the logs subresource of pods. Use "pods/logs" to match subresources.
