A <code>nil</code> channel is never ready for communication.

<p>
A channel may be closed with the built-in function
<a href="#Close"><code>close</code></a>.
The multi-valued assignment form of the
<a href="#Receive_operator">receive operator</a>
reports whether a received value was sent before
the channel was closed.

<p>
A single channel may be used in

  // first client attaches to stdin, and then remains open and accepts data until the client disconnects,
  // 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

### Bug or Regression

- Fix "dbus: connection closed by user" error after dbus daemon restart
  CVE-2023-27561 CVE-2023-25809 CVE-2023-28642: Bump fix runc v1.1.4 -> v1.1.5

* rbd: default image format to v2 instead of deprecated v1 ([#51574](https://github.com/kubernetes/kubernetes/pull/51574), [@dillaman](https://github.com/dillaman))
* Surface reasonable error when client detects connection closed. ([#51381](https://github.com/kubernetes/kubernetes/pull/51381), [@mengqiy](https://github.com/mengqiy))

        * When a `response_model` is declared, the same `response_model` type declaration won't be used as is, it will be "cloned" to create an new one (a cloned Pydantic `Field` with all the submodels cloned as well).

- Scheduler: in 1.29 pre-releases, enabling contextual logging slowed down pod scheduling. ([#121715](https://github.com/kubernetes/kubernetes/pull/121715), [@pohly](https://github.com/pohly)) [SIG Instrumentation and Scheduling]
