- EmptyDir memory backed volumes are sized as the minimum of pod allocatable memory on a host and an optional explicit user provided value. ([#100319](https://github.com/kubernetes/kubernetes/pull/100319), [@derekwaynecarr](https://github.com/derekwaynecarr)) [SIG Node]

  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]

* Make volume usage metrics available for Cinder ([#62668](https://github.com/kubernetes/kubernetes/pull/62668), [@zetaab](https://github.com/zetaab))

  * 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.

### SIG Storage

- Fixed CSI volume limits not showing up in node's capacity and allocatable ([#70540](https://github.com/kubernetes/kubernetes/pull/70540), [@gnufied](https://github.com/gnufied))

  - Remove redundant logging around calculating node utilization
  - Add configurable `--network` and `--rm` flags for docker in `Makefile`
  - Subtract DaemonSet pods' requests from node allocatable in the denominator while computing node utilization
  - Include taints by condition when determining if a node is unready/still starting
  - Fix `update-vendor.sh` to work on OSX and zsh

  * Prevent kubelet from setting allocatable < 0 for a resource upon initial creation. ([#46516](https://github.com/kubernetes/kubernetes/pull/46516), [@derekwaynecarr](https://github.com/derekwaynecarr))

* Bug fixes

- Fix the panic when kubelet registers if a node object already exists with no Status.Capacity or Status.Allocatable ([#96297](https://github.com/kubernetes/kubernetes/pull/96297), [@SataQiu](https://github.com/SataQiu)) [SIG Node]

- 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))
