- Generic ephemeral volumes, a new alpha feature under the `GenericEphemeralVolume` feature gate, provide a more flexible alternative to `EmptyDir` volumes: as with `EmptyDir`, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume...

- kubectl now loads config file once and uses persistent client config ([#71117](https://github.com/kubernetes/kubernetes/pull/71117), [@dixudx](https://github.com/dixudx))
- Printed `SizeLimit` of `EmptyDir` in `kubectl describe pod` outputs. ([#69279](https://github.com/kubernetes/kubernetes/pull/69279), [@dtaniwaki](https://github.com/dtaniwaki))

- Number of errors reported to the metric `storage_operation_duration_seconds_count` for emptyDir decreased significantly because previously one error was reported for each projected volume created.

  Drop support for the deprecated --delete-local-data from kubectl drain, users should use --delete-emptydir-data, instead. ([#125842](https://github.com/kubernetes/kubernetes/pull/125842), [@soltysh](https://github.com/soltysh)) [SIG CLI]

* The `emptyDir.sizeLimit` field is now correctly omitted from API requests and responses when unset. ([#50163](https://github.com/kubernetes/kubernetes/pull/50163), [@jingxu97](https://github.com/jingxu97))
