// container crashes or exits. The Pod's termination grace period countdown begins before the
  // PreStop hook is executed. Regardless of the outcome of the handler, the
  // container will eventually terminate within the Pod's termination grace
  // period (unless delayed by finalizers). Other management of the container blocks until the hook completes
  // or until the termination grace period is reached.

- Fixed a bug where hard evictions due to resource pressure allowed pods
  to use the full termination grace period instead of shutting down instantly. 
  This bug also affected force deleted pods. Both cases now receive a termination grace period of 1 second. ([#124063](https://github.com/kubernetes/kubernetes/pull/124063), [@olyazavr](https://github.com/olyazavr))

### Instrumentation

In v1.9 we focused on improving stability of the components owned by the SIG, including Heapster, Custom Metrics API adapters for Prometheus, and Stackdriver.

### Network

- Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))

- Kubelet did not report `kubelet_volume_stats_*` metrics for Generic Ephemeral Volumes. ([#105569](https://github.com/kubernetes/kubernetes/pull/105569), [@pohly](https://github.com/pohly))
- Kubelet's Node Grace Shutdown will terminate probes when shutting down ([#105215](https://github.com/kubernetes/kubernetes/pull/105215), [@rphillips](https://github.com/rphillips))

- When deleting objects using kubectl with the --force flag, you are no longer required to also specify --grace-period=0. ([#87776](https://github.com/kubernetes/kubernetes/pull/87776), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]

- Respect grace period when updating static pods. ([#106394](https://github.com/kubernetes/kubernetes/pull/106394), [@gjkim42](https://github.com/gjkim42)) [SIG Node and Testing]

* Add error message when trying to use clusterrole with namespace in kubectl ([#36424](https://github.com/kubernetes/kubernetes/pull/36424), [@xilabao](https://github.com/xilabao))

* Pods that are marked for deletion and have exceeded their grace period, but are not yet deleted, no longer count toward the resource quota.([#46542](https://github.com/kubernetes/kubernetes/pull/46542))


#### Dynamic Admission Control

* Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))
