#### DaemonSet
* [beta] DaemonSet supports history and rollback. See [Performing a Rollback on a DaemonSet](https://kubernetes.io/docs/tasks/manage-daemon/rollback-daemon-set/).

#### Deployments

* Add automatic etcd 3.2->3.1 and 3.1->3.0 minor version rollback support to gcr.io/google_container/etcd images. For HA clusters, all members must be stopped before performing a rollback. ([#59298](https://github.com/kubernetes/kubernetes/pull/59298), [@jpbetz](https://github.com/jpbetz))

* `kubectl rollout undo` now returns errors when attempting to rollback a deployment to a non-existent revision ([#70039](https://github.com/kubernetes/kubernetes/pull/70039), [@liggitt](https://github.com/liggitt))
    * `kubectl rollout undo` no longer uses the deprecated extensions/v1beta1 rollback API, which means that Events are no longer emitted when rolling back a deployment

- proxy/transport now supports Content-Encoding: deflate ([#76551](https://github.com/kubernetes/kubernetes/pull/76551), [@JieJhih](https://github.com/JieJhih))
- Admission webhooks are now properly called for `scale` and `deployments/rollback` subresources. ([#76849](https://github.com/kubernetes/kubernetes/pull/76849), [@liggitt](https://github.com/liggitt))

- cpumanager will now rollback state if updateContainerCPUSet failed, indicating that the container start failed. This change will prevent CPU leaks. ([#67430](https://github.com/kubernetes/kubernetes/pull/67430), [@choury](https://github.com/choury))

be migrated at the current time using the official Kubernetes procedure.

1.6 will also default to protobuf encoding if using etcd3.  **This change is
irreversible.**  To rollback, you must restore from a backup made before the
protobuf/etcd3 switch, and any changes since the backup will be lost.  As 1.5
does not support protobuf encoding, if you roll back to 1.5 after upgrading to

  This feature will not be fully enabled until a future Kubernetes release (likely to be v1.29), but is added in v1.28 to enable
  safe rollback on downgrade. ([#118339](https://github.com/kubernetes/kubernetes/pull/118339), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, Auth, Cloud Provider and Testing]

* `deployments/rollback` is now passed through validation/admission controllers ([#72271](https://github.com/kubernetes/kubernetes/pull/72271), [@jhrv](https://github.com/jhrv))
