## 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.

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

* Allow missing keys in jsonpath ([#31714](https://github.com/kubernetes/kubernetes/pull/31714), [@smarterclayton](https://github.com/smarterclayton))
* Changes 'kubectl rollout status' to wait until all updated replicas are available before finishing. ([#31499](https://github.com/kubernetes/kubernetes/pull/31499), [@areed](https://github.com/areed))

### 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))

* 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))
