### kubectl rolling-update: < v1.4.0 client vs >=v1.4.0 cluster

Old version kubectl's rolling-update command is compatible with Kubernetes 1.4 and higher only if you specify a new replication controller name. You will need to update to kubectl 1.4 or higher to use the rolling update command against a 1.4 cluster if you want to keep the original name, or you'll have to do two rolling updates.

### DaemonSet
* **[beta]** Introduce the rolling update feature for DaemonSet. See [Performing a Rolling Update on a DaemonSet](https://kubernetes.io/docs/tasks/manage-daemon/update-daemon-set/).

### Deployment

([#87077](https://github.com/kubernetes/kubernetes/pull/87077), [@soltysh](https://github.com/soltysh)) [SIG Architecture, CLI and Testing]
- The deprecated command `kubectl rolling-update` has been removed ([#88057](https://github.com/kubernetes/kubernetes/pull/88057), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG Architecture, CLI and Testing]

#### client-go:

* The `batch/v2alpha1.ScheduledJob` was removed. Migrate to `batch/v1beta.CronJob` to continue managing time based jobs.

- Created a new `kubectl rollout restart` command that does a rolling restart of a deployment. ([#76062](https://github.com/kubernetes/kubernetes/pull/76062), [@apelisse](https://github.com/apelisse))

- Revised the logic for DaemonSet rolling update to exclude nodes if scheduling constraints are not met.

* fix: azure disk could not mounted on Standard_DC4s/DC2s instances ([#86612](https://github.com/kubernetes/kubernetes/pull/86612), [@andyzhangx](https://github.com/andyzhangx))
* Fix v1.17.0 regression in reflector relist causing master rolling upgrade to fail for large clusters due to excessive list calls to etcd ([#86824](https://github.com/kubernetes/kubernetes/pull/86824), [@jpbetz](https://github.com/jpbetz))
