#### 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))


## **External Dependency Version Information**

A parsing ambiguity arises when the type parameter list for a generic type
declares a single type parameter <code>P</code> with a constraint <code>C</code>
such that the text <code>P C</code> forms a valid expression:
