- 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))

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.
