* Custom apiservers built with the latest apiserver library will have the 100MB limit on the body of resource requests as well. The limit can be altered via ServerRunOptions.MaxRequestBodyBytes.
    * The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.

* New alpha feature limits the number of processes running in a pod. Cluster administrators will be able to place limits by using the new kubelet command line parameter --pod-max-pids. Note that since this is a alpha feature they will need to enable the "SupportPodPidsLimit" feature. By default, we do not set any maximum limit, If an administrator wants to enable this, they should enable SupportPodPidsLimit=true in the --feature-gates=...

* Alpha feature: allows users to set storage limit to isolate EmptyDir volumes. It enforces the limit by evicting pods that exceed their storage limits   ([#45686](https://github.com/kubernetes/kubernetes/pull/45686), [@jingxu97](https://github.com/jingxu97))

* Bug fixes

  - Added validation to enforce the hugepage aggregated container limits to be smaller than or equal to pod-level limits. This was already enforced with the defaulted requests from the specified limits, however it did not make it clear about both hugepage requests and limits.

- kube-scheduler removed `AzureDiskLimits` ,`CinderLimits` `EBSLimits` and `GCEPDLimits` plugin. Given the corresponding CSI driver reports how many volumes a node can handle in NodeGetInfoResponse, the kubelet stores this limit in CSINode and the scheduler then knows the limit of the driver on the node. Removed plugins AzureDiskLimits, CinderLimits, EBSLimits and GCEPDLimits if you explicitly enabled them in the scheduler config. ([#124003](https://github.com/kubernetes/kubernetes/pull/124003), ...
