Foundation.  If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever published
by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
versions of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.

- The `SecurityContextDeny` admission plugin is going deprecated and will be removed in future versions. ([#115879](https://github.com/kubernetes/kubernetes/pull/115879), [@mtardy](https://github.com/mtardy))

### API Change

// If the line was too long for the buffer then isPrefix is set and the
// beginning of the line is returned. The rest of the line will be returned
// from future calls. isPrefix will be false when returning the last fragment
// of the line. The returned buffer is only valid until the next call to
// ReadLine. ReadLine either returns a non-nil line or it returns an error,
// never both.

- kubectl: `--use-openapi-print-columns` has been deprecated in favor of `--server-print`, and will be removed in a future version. ([#65601](https://github.com/kubernetes/kubernetes/pull/65601), [@liggitt](https://github.com/liggitt))...

Pruning is activated by setting `spec.preserveUnknownFields: false` in the CustomResourceDefinition. A future apiextensions.k8s.io/v1 variant of CRDs will enforce pruning.

Pruning requires that CRD developer provides complete, structural validation schemas, either at the top-level or for all versions of the CRD.

- The CSINodeInfo feature gate is deprecated and will be removed in a future release. The storage.k8s.io/v1beta1 CSINode object is deprecated and will be removed in a future release. ([#83474](https://github.com/kubernetes/kubernetes/pull/83474), [@msau42](https://github.com/msau42))

### Kubernetes API Reference Documentation

- Kubeadm: the `--feature-gates` flag is deprecated and no-op for `kubeadm upgrade apply/plan`, and it will be removed in a future release. The upgrade workflow is not designed to reconfigure the cluster. Please edit the 'featureGates' field of ClusterConfiguration...

func f() {
	print(a)
}

func hello() {
	a = "hello, world"
	go f()
}

<p>
calling <code>hello</code> will print <code>"hello, world"</code>
at some point in the future (perhaps after <code>hello</code> has returned).

The exit of a goroutine is not guaranteed to be synchronized before
any event in the program.
