  * Node stability can be improved by reserving [resources](https://github.com/kubernetes/kubernetes/blob/release-1.2/docs/proposals/node-allocatable.md) for the base operating system using --system-reserved and --kube-reserved Kubelet flags
  * Liveness and readiness probes now support more configuration parameters:
periodSeconds, successThreshold, failureThreshold

    `--cgroups-per-qos=false`.
  * If `kube-reserved` and/or `system-reserved` are specified, node allocatable
    will be enforced on all pods by default. To opt-out set
    `--enforce-node-allocatable=””`
  * Hard Eviction Thresholds will be subtracted from Capacity while calculating
    Node Allocatable. This will result in a reduction of schedulable capacity in

- 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]

* 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.

  - 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

  // Defaults to Capacity.
  // +optional

  // NodePhase is the recently observed lifecycle phase of the node.

  * 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))
