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.

* kube-apiserver now drops unneeded path information if an older version of Windows kubectl sends it. ([#44421](https://github.com/kubernetes/kubernetes/pull/44421), [@mml](https://github.com/mml))


#### Application autoscaling

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s).

- Spedup kubectl by >10 when calling out to kube-apiserver for discovery information. ([#73345](https://github.com/kubernetes/kubernetes/pull/73345), [@sttts](https://github.com/sttts))
- Fixed watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

* The PodSecurityPolicy annotation `kubernetes.io/psp` on pods is only set once on create. ([#55486](https://github.com/kubernetes/kubernetes/pull/55486), [@sttts](https://github.com/sttts))

* Adds deleting pods created by DaemonSet assigned to not existing nodes. ([#73401](https://github.com/kubernetes/kubernetes/pull/73401), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
* Fix watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

* Fix support for callable class dependencies with `yield`. PR [#1365](https://github.com/tiangolo/fastapi/pull/1365) by [@mrosales](https://github.com/mrosales).
* Fix/remove incorrect error logging when a client sends invalid payloads. PR [#1351](https://github.com/tiangolo/fastapi/pull/1351) by [@dbanty](https://github.com/dbanty).

  With WatchBookmark feature, clients are able to request watch events with BOOKMARK type. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. ([#79786](https://github.com/kubernetes/kubernetes/pull/79786), [@wojtek-t](https://github.com/wojtek-t))

* Update Cluster Autoscaler to version 1.3.7. ([#74136](https://github.com/kubernetes/kubernetes/pull/74136), [@jkaniuk](https://github.com/jkaniuk))
* Fix watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))

- 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))
