- K8s.io/client-go/tools/record.EventBroadcaster: after Shutdown() is called, the broadcaster now gives up immediately after a failure to write an event to a sink. Previously it tried multiple times for 12 seconds in a goroutine. ([#115514](https://github.com/kubernetes/kubernetes/pull/115514), [@pohly](https://github.com/pohly)) [SIG API...

### Bug or Regression

- Fix OpenAPI v3 not being cleaned up after deleting APIServices ([#120108](https://github.com/kubernetes/kubernetes/pull/120108), [@tnqn](https://github.com/tnqn)) [SIG API Machinery and Testing]

* Add a way to pass extra arguments to etcd. ([#63961](https://github.com/kubernetes/kubernetes/pull/63961), [@mborsz](https://github.com/mborsz))
* kubelet: fix hangs in updating Node status after network interruptions/changes between the kubelet and API server ([#63492](https://github.com/kubernetes/kubernetes/pull/63492), [@liggitt](https://github.com/liggitt))



# v1.8.13

- DRA: when the scheduler had to deallocate a claim after a node became unsuitable for a pod, it might have needed more attempts than really necessary. This was fixed by first disabling allocations. ([#120428](https://github.com/kubernetes/kubernetes/pull/120428), [@pohly](https://github.com/pohly))

- Added reconstruction of SELinux mount context after kubelet restart. Feature `SELinuxMountReadWriteOncePod` is now fully implemented and kubelet does not lose its cache of SELinux contexts after kubelet process restart.
