A send on an unbuffered channel can proceed if a receiver is ready.
A send on a buffered channel can proceed if there is room in the buffer.
A send on a closed channel proceeds by causing a <a href="#Run_time_panics">run-time panic</a>.
A send on a <code>nil</code> channel blocks forever.

#### Application autoscaling

- Both apiserver_request_duration_seconds metrics and RequestReceivedTimestamp fields of an audit event now take into account the time a request spends in the apiserver request filters. ([#94903](https://github.com/kubernetes/kubernetes/pull/94903), [@tkashem](https://github.com/tkashem))
- Build/lib/release: Explicitly use '--platform' in building server images
  

- Kubeadm: enabled the --experimental-watch-progress-notify-interval flag for etcd and set it to 5s. The flag specifies an interval at which etcd sends watch data to the kube-apiserver. ([#111383](https://github.com/kubernetes/kubernetes/pull/111383), [@p0lyn0mial](https://github.com/p0lyn0mial))

* For admission webhooks registered for DELETE operations on k8s built APIs or CRDs, the apiserver now sends the existing object as admissionRequest.Request.OldObject to the webhook.  ([#76346](https://github.com/kubernetes/kubernetes/pull/76346), [@caesarxuchao](https://github.com/caesarxuchao))

- HPA reaction to metric changes has been spend up by removing the scale up forbidden window. ([#66615](https://github.com/kubernetes/kubernetes/pull/66615), [@jbartosik](https://github.com/jbartosik))
