This allows the scheduler to handle cluster events faster with less memory.
  
  Specific node events include updates to taints, tolerations or allocatable.
  In-tree plugins now ignore node updates that don't modify any of these fields. ([#127220](https://github.com/kubernetes/kubernetes/pull/127220), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling and Storage]

  * For alpha, volume resizing supports only Gluster volumes.

* [alpha] Provide capacity isolation and resource management for local ephemeral storage

  * You can now set container requests, container limits, and node allocatable reservations for the new `ephemeral-storage` resource.

  * The `ephemeral-storage` resource includes all the disk space a container might consume with container overlay or scratch.

- The `EmptyDir` memory backed volumes are sized as the minimum of pod allocatable memory on a host and an optional explicit user provided value. ([#101048](https://github.com/kubernetes/kubernetes/pull/101048), [@dims](https://github.com/dims))

- Kubelet: wait for node allocatable ephemeral-storage data. ([#101882](https://github.com/kubernetes/kubernetes/pull/101882), [@jackfrancis](https://github.com/jackfrancis))
