- The alpha `Initializers` admission plugin is no longer enabled by default. This matches the off-by-default behavior of the alpha API which drives initializer behavior. ([#66039](https://github.com/kubernetes/kubernetes/pull/66039), [@liggitt](https://github.com/liggitt))

* Prevent `resourceVersion` updates for custom resources on no-op writes. ([#67562](https://github.com/kubernetes/kubernetes/pull/67562), [@nikhita](https://github.com/nikhita))

#### Rkt runtime Known Issues

- A detailed list of known issues can be found [here](https://github.com/kubernetes/kubernetes.github.io/blob/release-1.3/docs/getting-started-guides/rkt/notes.md)

*More Instructions coming soon*

## Provider-specific Notes

* AWS
  * Support for ap-northeast-2 region (Seoul)
  * Allow cross-region image pulling with ECR

#### Scalability

* The HorizontalPodAutoscaler controller will now only send updates when it has new status information, reducing the number of writes caused by the controller. ([#47078](https://github.com/kubernetes/kubernetes/pull/47078), [@DirectXMan12](https://github.com/DirectXMan12))
