* Use context to check client closed instead of http.CloseNotifier in processing watch request which will reduce 1 goroutine for each request if proto is HTTP/2.x . ([#85408](https://github.com/kubernetes/kubernetes/pull/85408), [@answer1991](https://github.com/answer1991))

- 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 Machinery]

* Allow setting the Host header in a httpGet probe ([#24292](https://github.com/kubernetes/kubernetes/pull/24292), [@errm](https://github.com/errm))
* Fix goroutine leak in ssh-tunnel healthcheck. ([#24487](https://github.com/kubernetes/kubernetes/pull/24487), [@cjcullen](https://github.com/cjcullen))

* kube-apiserver: Fixed a regression accepting patch requests > 1MB ([#84963](https://github.com/kubernetes/kubernetes/pull/84963), [@liggitt](https://github.com/liggitt))
* kube-apiserver: fixed a bug that could cause a goroutine leak if the apiserver encountered an encoding error serving a watch to a websocket watcher ([#84693](https://github.com/kubernetes/kubernetes/pull/84693), [@tedyu](https://github.com/tedyu))
