* Fixes an issue with `kubectl set` commands encountering conversion errors for ReplicaSet and DaemonSet objects ([#53158](https://github.com/kubernetes/kubernetes/pull/53158), [@liggitt](https://github.com/liggitt))


# v1.8.0

	loggingOptions.JSONEncoding = true
	if cfg != nil {
		udsAddr := filepath.Join(cfg.CNIAgentRunDir, constants.LogUDSSocketName)
		// Tee all logs to UDS. Stdout will go to kubelet (hard to access, UDS will be read by the CNI DaemonSet and exposed
		// by normal `kubectl logs`
		if file.Exists(udsAddr) {
			loggingOptions.WithTeeToUDS(udsAddr, constants.UDSLogPath)
		}

- DaemonSet: Fix bug- daemonset didn't create pod after node have enough resource ([#67337](https://github.com/kubernetes/kubernetes/pull/67337), [@linyouchong](https://github.com/linyouchong))

		ns := s.namespaces.Get(pod.Namespace, "")
		if ns == nil {
			log.Warnf("failed to find namespace %s for pod %s", pod.Namespace, pod.Name)
		}

		// Exclude ztunnels, and terminated daemonset pods
		// from the snapshot.
		if !util.IsZtunnelPod(s.systemNamespace, pod) &&
			!kube.CheckPodTerminal(pod) &&
			util.PodRedirectionActive(pod) {
			pods = append(pods, pod)
		}
	}
	return pods
}

    * of DaemonSet Pod already exists, it will be replaced.
    * DaemonSet controller will only perform these operations when creating DaemonSet Pods;
    * and those operations will only modify the Pods of DaemonSet, no changes are made to the
    * `.spec.template` of DaemonSet.
* fix formatAndMount func issue on Windows ([#63248](https://github.com/kubernetes/kubernetes/pull/63248), [@andyzhangx](https://github.com/andyzhangx))

Extensibility. SIG API Machinery added a new class of admission control webhooks (mutating), and brought the admission control webhooks to beta.

### Apps

The core workloads API, which is composed of the DaemonSet, Deployment, ReplicaSet, and StatefulSet kinds, has been promoted to GA stability in the apps/v1 group version. As such, the apps/v1beta2 group version is deprecated, and all new code should use the kinds in the apps/v1 group version.

* fixed foreground deletion of podtemplates ([#60683](https://github.com/kubernetes/kubernetes/pull/60683), [@nilebox](https://github.com/nilebox))

* Conformance tests are added for the DaemonSet kinds in the apps/v1 group version. Deprecated versions of DaemonSet will not be tested for conformance, and conformance is only applicable to release 1.10 and later.

- Revised the logic for DaemonSet rolling update to exclude nodes if scheduling constraints are not met.
  This eliminates the problem of rolling updates to a DaemonSet getting stuck around tolerations. ([#120786](https://github.com/kubernetes/kubernetes/pull/120786), [@mochizuki875](https://github.com/mochizuki875)) [SIG Apps and Testing]

// The API Server will fail validation of all requests that attempt to mutate
// the Data field. ControllerRevisions may, however, be deleted. Note that, due to its use by both
// the DaemonSet and StatefulSet controllers for update and rollback, this object is beta. However,
// it may be subject to name and representation changes in future releases, and clients should not

    * setting `KUBE_PROXY_DAEMONSET=true` in kube-up will now set a `node.kubernetes.io/kube-proxy-ds-ready=true` label on new nodes. In v1.16, the kube-proxy daemonset add-on will switch to using that label as a node selector.
    * In 1.16, the masq-agent daemonset add-on will switch to using `node.kubernetes.io/masq-agent-ds-ready` as a node selector.
