A send statement sends a value on a channel.
The channel expression must be of <a href="#Channel_types">channel type</a>,
the channel direction must permit send operations,
and the type of the value to be sent must be <a href="#Assignability">assignable</a>
to the channel's element type.

* [Breaking change, client-go]: The WaitFor function returns, probably an ErrWaitTimeout, when the done channel is closed, even if the `WaitFunc` doesn't handle the done channel. ([#72364](https://github.com/kubernetes/kubernetes/pull/72364), [@kdada](https://github.com/kdada))

- Fixed a storage bug around multipath. iSCSI and Fibre Channel devices attached to nodes via multipath now resolve correctly if partitioned. ([#129183](https://github.com/kubernetes/kubernetes/pull/129183), [@RomanBednar](https://github.com/RomanBednar)) [SIG Storage]

* [stable] Support Attach and Detach operations for ReadWriteOnce (RWO) volumes that use iSCSI and Fibre Channel plugins.

* [stable] Expose storage usage metrics

  * The available capacity of a given Persistent Volume (PV) is available by calling the Kubernetes metrics API.

* [stable] Volume plugin metrics
