  * Logs usage and root filesystem usage of a container, volumes usage of a pod and node disk usage are exposed through Kubelet new metrics API.

### Experimental Features

  * Dynamic Provisioning of PersistentVolumes: Kubernetes previously required all
volumes to be manually provisioned by a cluster administrator before use. With

 *  Upgrade: [Okio 3.16.3][okio_3_16_3].


## Version 5.2.1

 *  Fix: Don't crash when calling `Socket.shutdownOutput()` or `shutdownInput()` on an `SSLSocket`
    on Android API 21 through 23. This method throws an `UnsupportedOperationException`, so we now
    catch that and close the underlying stream instead.

 *  Upgrade: [Okio 3.16.1][okio_3_16_1].

# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

### Synchronous Get ([.kt][SynchronousGetKotlin], [.java][SynchronousGetJava])

* Resolves a bug that prevented sending a multi-version custom resource to an admission webhook. ([#79495](https://github.com/kubernetes/kubernetes/pull/79495), [@liggitt](https://github.com/liggitt))
* Pass-through volume MountOptions to global mount (NodeStageVolume) on the node for CSI ([#80191](https://github.com/kubernetes/kubernetes/pull/80191), [@davidz627](https://github.com/davidz627))

* remove deprecated generated typed clients ([#26336](https://github.com/kubernetes/kubernetes/pull/26336), [@caesarxuchao](https://github.com/caesarxuchao))
* Kubenet host-port support through iptables ([#25604](https://github.com/kubernetes/kubernetes/pull/25604), [@freehan](https://github.com/freehan))

- This PR adds additional validation for endpoint ip configuration while iterating through queried endpoint list. ([#117224](https://github.com/kubernetes/kubernetes/pull/117224), [@princepereira](https://github.com/princepereira)) [SIG Network and Windows]

    assertEquals(2, (int) result.next());
    assertThrows(NullPointerException.class, () -> result.hasNext());
    assertThrows(NullPointerException.class, () -> result.next());
    // There is no way to get "through" to the 3.  Buh-bye
  }

  public void testConcatVarArgsContainingNull() {
    assertThrows(
        NullPointerException.class,
        () ->
            Iterators.concat(

## Changelog since v1.5.2

### Other notable changes

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not.  ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))
