- Added swap to stats to Summary API and Prometheus endpoints (stats/summary and /metrics/resource). ([#118865](https://github.com/kubernetes/kubernetes/pull/118865), [@iholder101](https://github.com/iholder101))
- Added the implementation for `PodRecreationPolicy` to wait for the creation of pods once the existing ones are fully terminated. ([#117015](https://github.com/kubernetes/kubernetes/pull/117015), [@kannon92](https://github.com/kannon92))
