- A new sleep action for the `PreStop` lifecycle hook was added, allowing containers to pause for a specified duration before termination. ([#119026](https://github.com/kubernetes/kubernetes/pull/119026), [@AxeZhan](https://github.com/AxeZhan))

- Fixes a bug that when there is a "connection refused" error, the reflector's ListAndWatch func will return directly but what expected is that sleep 1 second and rewatch since the specified resourceVersion.

When the function terminates, its goroutine also terminates.
If the function has any return values, they are discarded when the
function completes.

cluster-wide seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.
