During server startup, prior to the server reporting healthy (via `/healthz`), not all API groups may be reported.
Wait for the server to report healthy (via `/healthz`) before depending on the information provided by the discovery APIs.

- Generating informers for packages in directories containing dots in their name is broken. This will be fixed in v1.16.1. ([#82860](https://github.com/kubernetes/kubernetes/issues/82860))
- kube-scheduler won't be able to report scheduling Events if `events.k8s.io/v1beta1` API is disabled. We are targeting the fix for v1.16.2 ([#83203](https://github.com/kubernetes/kubernetes/issues/83203))

incorrectly reject pods with `OutOfCpu` errors if they were rapidly scheduled after other pods were reported as complete in the API. The Kubelet now waits to report the phase of a pod as terminal in the API until all running containers are guaranteed to have stopped and no new containers can be started.  Short-lived pods may take slightly longer (~1s) to report Succeeded or Failed after this change.

- ServiceOwnsFrontendIP shouldn't report error when the public IP doesn't match ([#102516](https://github.com/kubernetes/kubernetes/pull/102516), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

### Other (Cleanup or Flake)

- kubelets that specify `--cloud-provider` now only report addresses in Node status as determined by the cloud provider (unless `--hostname-override` is used to force reporting of the specified hostname) ([#65594](https://github.com/kubernetes/kubernetes/pull/65594), [@liggitt](https://github.com/liggitt))...

- Terminating a restartPolicy=Never pod no longer has a chance to report the pod succeeded when it actually failed. ([#88440](https://github.com/kubernetes/kubernetes/pull/88440), [@smarterclayton](https://github.com/smarterclayton)) [SIG Node and Testing]

- Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. ([#73892](https://github.com/kubernetes/kubernetes/pull/73892), [@smarterclayton](https://github.com/smarterclayton))
