- Implemented `event_handling_duration_seconds` metric, which is the time the scheduler takes to handle each kind of events. ([#125929](https://github.com/kubernetes/kubernetes/pull/125929), [@sanposhiho](https://github.com/sanposhiho))

interface{ ~int | ~string }  // type parameter only: implements comparable (int, string types are strictly comparable)
interface{ comparable }      // type parameter only: implements comparable (comparable implements itself)
interface{ ~int | ~[]byte }  // type parameter only: does not implement comparable (slices are not comparable)
interface{ ~struct{ any } }  // type parameter only: does not implement comparable (field any is not strictly comparable)

    Potential impacts:

  * [alpha] CRI now supports specifying the GID of the container at both LinuxSandboxSecurityContext and LinuxContainerSecurityContext in addition to specifying the UID. Support is implemented for dockershim. [@krmayankk]

* Created a new `dryRun` query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the `dryRun` query parameter.

- Implemented the `prescore` extension point for the `volumeBinding` plugin. It now returns skip if it doesn't do anything in Score.

- Graduated the container resource metrics feature on `HPA` to beta. ([#116046](https://github.com/kubernetes/kubernetes/pull/116046), [@sanposhiho](https://github.com/sanposhiho))
- Implemented API streaming for the `watch-cache`
  

- Implemented API for streaming for the `etcd` store implementation.

- Implemented a queueing hint for PersistentVolumeClaim/Add event in the `CSILimit` plugin. ([#124703](https://github.com/kubernetes/kubernetes/pull/124703), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Storage]

debugging, similar to how `kubectl exec` runs a process in an existing container. Also like `kubectl exec`, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so [process namespace sharing](https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/) must be enabled to view process from other containers in the pod.
