* Minimum CPU limits is 10m. This is a Linux Kernel limitation
  * “kubectl rollout undo” (i.e. rollback) will hang on paused deployments, because
paused deployments can’t be rolled back (this is expected), and the command
waits for rollback events to return the result. Users should use “kubectl
rollout resume” to resume a deployment before rolling back.

### SIG CLI

- `kubectl apply` can now change a deployment strategy from rollout to recreate without explicitly clearing the rollout-related fields ([#70436](https://github.com/kubernetes/kubernetes/pull/70436), [@liggitt](https://github.com/liggitt))

* AWS: SSL support for ELB listeners through annotations ([#23495](https://github.com/kubernetes/kubernetes/pull/23495), [@therc](https://github.com/therc))
* Implement `kubectl rollout status` that can be used to watch a deployment's rollout status ([#19946](https://github.com/kubernetes/kubernetes/pull/19946), [@janetkuo](https://github.com/janetkuo))

* Fixes ability for admin/edit/view users to see controller revisions, needed for kubectl rollout commands ([#70699](https://github.com/kubernetes/kubernetes/pull/70699), [@liggitt](https://github.com/liggitt))

  * `kubectl rollout` supports undo and history for DaemonSet ([#46144](https://github.com/kubernetes/kubernetes/pull/46144), [@janetkuo](https://github.com/janetkuo))

  * `kubectl rollout` supports status and history for StatefulSet  ([#46669](https://github.com/kubernetes/kubernetes/pull/46669), [@kow3ns](https://github.com/kow3ns)).

- Changed the error message of `kubectl rollout restart` when subsequent `kubectl rollout restart` commands are executed within a second ([#113040](https://github.com/kubernetes/kubernetes/pull/113040), [@ardaguclu](https://github.com/ardaguclu))

- The `kubectl top` command now includes a `--sort-by` option to sort by `memory` or `cpu`. ([#75920](https://github.com/kubernetes/kubernetes/pull/75920), [@artmello](https://github.com/artmello))
- `kubectl rollout restart` now works for DaemonSets and StatefulSets. ([#77423](https://github.com/kubernetes/kubernetes/pull/77423), [@apelisse](https://github.com/apelisse))

  that provide new subcommands. Refer to the documentation for more information.

- `kubectl rollout` and `rollback` now support StatefulSet.

- `kubectl scale` now uses the Scale subresource for kinds in the apps/v1beta2 group.

- `kubectl create configmap` and `kubectl create secret` subcommands now support

### Documentation

- Added descriptions and examples for the situation of using `kubectl rollout restart` without specifying a particular deployment. ([#120118](https://github.com/kubernetes/kubernetes/pull/120118), [@Ithrael](https://github.com/Ithrael))

## Notable Changes to Existing Behavior

### Deployments

- ReplicaSets of paused Deployments are now scaled while the Deployment is paused. This is retroactive to existing Deployments.
- When scaling a Deployment during a rollout, the ReplicaSets of all Deployments are now scaled proportionally based on the number of replicas they each have instead of only scaling the newest ReplicaSet.
