restarts. More information [here](https://github.com/kubernetes/kubernetes/issues/20995)
  * Pod IP allocation-related issues. Deleting the docker checkpoint prior to
restarting the daemon alleviates this issue, but hasn’t been verified to
completely eliminate the IP allocation issue. More information [here](https://github.com/kubernetes/kubernetes/issues/21523#issuecomment-191498969)

- Dynamic resource allocation: when a claim uses "wait for first consumer" allocation (the default), then it will now get deallocated after it was used by a pod. That ensures that the next pod isn't affected by previous scheduling decision and that resources are not kept allocated unless really needed. If keeping a claim allocated is desired, use "immediate allocation." ([#118936](https://github.com/kubernetes/kubernetes/pull/118936), [@pohl...
