// If the provisioner or an external controller can support the specified data source,
  // it will create a new volume based on the contents of the specified data source.
  // When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
  // and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.

* HTTP transport now uses `context.Context` to cancel dial operations. k8s.io/client-go/transport/Config struct has been updated to accept a function with a `context.Context` parameter. This is a breaking change if you use this field in your code. ([#60012](https://github.com/kubernetes/kubernetes/pull/60012), [@ash2k](https://github.com/ash2k))

- K8s.io/apimachinery/pkg/util/runtime: Added support for new calls to handle panics and errors in the context where they occur. `PanicHandlers` and `ErrorHandlers` now must accept a context parameter for that. Log output is structured instead of unstructured. ([#121970](https://github.com/kubernetes/kubernetes/pull/121970), [@pohly](https://github.com/pohly)) [SIG API Machinery and Instrumentation]...

- `kubectl config set-context` can now set attributes of the current context, such as the current namespace, by passing `--current` instead of a specific context name ([#66140](https://github.com/kubernetes/kubernetes/pull/66140), [@liggitt](https://github.com/liggitt))

t".Request).{Do,DoRaw,Stream,Watch}` now require callers to pass a `context.Context` as an argument. The context is used for timeout and cancellation signaling and to pass supplementary information to round trippers in the wrapped transport chain. If you don't need any of this functionality, it is sufficient to pass a context created with `context.Background()` to these functions. The `(*"k8s.io/client-go/rest".Request).Context` method is removed now that all methods that execute a request accept...

This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:
