* Fixed a bug the in scheduler cache by using Pod UID as the cache key instead of namespace/name ([#61069](https://github.com/kubernetes/kubernetes/pull/61069), [@anfernee](https://github.com/anfernee))

* kubelet now accepts a --cni-cache-dir option, which defaults to /var/lib/cni/cache, where CNI stores cache files. ([#78908](https://github.com/kubernetes/kubernetes/pull/78908), [@dcbw](https://github.com/dcbw))
