<p>
For an argument <code>ch</code> with a <a href="#Core_types">core type</a>
that is a <a href="#Channel_types">channel</a>, the built-in function <code>close</code>
records that no more values will be sent on the channel.
It is an error if <code>ch</code> is a receive-only channel.

Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports this functionality and implements the "CLONE_VOLUME" capability in its CSI driver, then the new volume becomes a clone of the source volume.

These changes are reflected in the following Kubernetes enhancements:
([#625](https://github.com/kubernetes/enhancements/issues/625))

  // at which time stdin is closed and remains closed until the container is restarted. If this
  // flag is false, a container processes that reads from stdin will never receive an EOF.
  // Default is false
  // +optional
  optional bool stdinOnce = 17;

  // Whether this container should allocate a TTY for itself, also requires 'stdin' to be true.
  // Default is false.
  // +optional
  optional bool tty = 18;

* Update debian-iptables and hyperkube-base images to include CVE fixes. ([#67365](https://github.com/kubernetes/kubernetes/pull/67365), [@ixdy](https://github.com/ixdy))
* Immediately close the other side of the connection when proxying. ([#67288](https://github.com/kubernetes/kubernetes/pull/67288), [@MHBauer](https://github.com/MHBauer))

- Apiserver add a new flag --goaway-chance which is the fraction of requests that will be closed gracefully(GOAWAY) to prevent HTTP/2 clients from getting stuck on a single apiserver. 
  After the connection closed(received GOAWAY), the client's other in-flight requests won't be affected, and the client will reconnect. 

    * The cache can be disabled per dependency declaration, using `use_cache=False` as in `Depends(your_dependency, use_cache=False)`.
    * Updated docs at: [Using the same dependency multiple times](https://fastapi.tiangolo.com/tutorial/dependencies/sub-dependencies/#using-the-same-dependency-multiple-times).

* hack/local-up-cluster.sh now enables kubelet authentication/authorization by default (they can be disabled with KUBELET_AUTHENTICATION_WEBHOOK=false and KUBELET_AUTHORIZATION_WEBHOOK=false ([#71690](https://github.com/kubernetes/kubernetes/pull/71690), [@liggitt](https://github.com/liggitt))

* Switch JSON marshal/unmarshal to json-iterator library.  Performance should be close to previous with no generated code. ([#48287](https://github.com/kubernetes/kubernetes/pull/48287), [@thockin](https://github.com/thockin))

- Kubelet don't forcefully close active connections on heartbeat failures, using the http2 health check mechanism to detect broken connections. Users can force the previous behavior of the kubelet by setting the environment variable DISABLE_HTTP2. ([#108107](https://github.com/ku...
