* gitRepo volumes in pods no longer require git 1.8.5 or newer; older git versions are now supported. ([#62394](https://github.com/kubernetes/kubernetes/pull/62394), [@jsafrane](https://github.com/jsafrane))

umes) feature allows any existing storage driver that supports dynamic provisioning to be used as an ephemeral volume with the volume’s lifecycle bound to the Pod. It can be used to provide scratch storage that is different from the root disk, for example persistent memory, or a separate local disk on that node. All StorageClass parameters for volume provisioning are supported. All features supported with PersistentVolumeClaims are supported, such as storage capacity tracking, snapshots and restore,...

- StatefulSet is supported in `kubectl autoscale` command ([#71103](https://github.com/kubernetes/kubernetes/pull/71103), [@Pingan2017](https://github.com/Pingan2017))

* vSphere cloud provider: vSphere Storage policy Support for dynamic volume provisioning ([#46176](https://github.com/kubernetes/kubernetes/pull/46176), [@BaluDontu](https://github.com/BaluDontu))
* Add support for emitting metrics from openstack cloudprovider about storage operations. ([#46008](https://github.com/kubernetes/kubernetes/pull/46008), [@NickrenREN](https://github.com/NickrenREN))
