* Change GCE installs (kube-up.sh) to use GCI/COS for node OS, by default. ([#46512](https://github.com/kubernetes/kubernetes/pull/46512), [@thockin](https://github.com/thockin))
* Use CollisionCount for collision avoidance when creating ControllerRevisions in StatefulSet controller ([#50490](https://github.com/kubernetes/kubernetes/pull/50490), [@liyinan926](https://github.com/liyinan926))
