#### **Audit**

*   Fixed a bug so that `kube-apiserver` now waits for open connections to finish before exiting. This fix provides graceful shutdown and ensures that the audit backend no longer drops events on shutdown. ([#53695](https://github.com/kubernetes/kubernetes/pull/53695),[ @hzxuzhonghu](https://github.com/hzxuzhonghu))

## Changelog since v1.10.9

### Other notable changes

* Do not remove shutdown nodes from api-server for vSphere. ([#70291](https://github.com/kubernetes/kubernetes/pull/70291), [@gnufied](https://github.com/gnufied))
    * Fixes volume detach from shutdown nodes.

### Introducing Graceful Node Shutdown (Alpha)

The `GracefulNodeShutdown` feature is now in Alpha. This allows kubelet to be aware of node system shutdowns, enabling graceful termination of pods during a system shutdown. This feature can be [enabled through feature gate](https://docs.k8s.io/concepts/architecture/nodes/#graceful-node-shutdown).
