  * Liveness and readiness probes now support more configuration parameters:
periodSeconds, successThreshold, failureThreshold
  * The new ReplicaSet API (Beta) in the Extensions API group is similar to

- `StartupProbe` was explicitly stopped when the `successThreshold` was reached.
  This eliminated the problem of executing `StartupProbe` more times than
  the `successThreshold`. ([#121206](https://github.com/kubernetes/kubernetes/pull/121206), [@mochizuki875](https://github.com/mochizuki875))
