    deletion of the Node object, deletion of the instance in the cloud provider,

    This helps prevent "split brain" scenarios in clustered applications by
    ensuring that unreachable pods will not be presumed dead unless some
    "fencing" operation has provided one of the above indications.

- DRA kubelet: Fixed the kubelet to also clean up `ResourceSlices` in some additional failure scenarios (driver was removed forcibly or crashed and did not restart). ([#132058](https://github.com/kubernetes/kubernetes/pull/132058), [@pohly](https://github.com/pohly)) [SIG Node and Testing]

**Note**: You probably don't need `contextvars`, and you should probably avoid using them. But they are powerful and useful in some advanced scenarios, for example, migrating from code that used Flask's `g` semi-global variable.
