- [beta] Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked ([docs](http://kubernetes.io/docs/user-guide/deployments/#failed-deployment)) ([kubernetes/features#122](https://github.com/kubernetes/enhancements/issues/122))

## 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.
