- Fix incorrect calculation for ResourceQuota with PriorityClass as its scope. ([#117828](https://github.com/kubernetes/kubernetes/pull/117828), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG API Machinery]

- Added `apiserver_watch_list_duration_seconds` metrics which will measure response latency distribution in seconds for watchlist requests broken by group, version, resource and scope. ([#120490](https://github.com/kubernetes/kubernetes/pull/120490), [@p0lyn0mial](https://github.com/p0lyn0mial))

     * The value is, e.g.  <br>
     * comment: Domain attribute for the search parameter cookie. Set to the domain scope you want the cookie to be available on (e.g., example.com).
     * @return The value of found property. (NotNull: if not found, exception but basically no way)
     */
    String getCookieSearchParameterDomain();

- Improved logging when volume times out waiting for attach/detach. ([#108628](https://github.com/kubernetes/kubernetes/pull/108628), [@RomanBednar](https://github.com/RomanBednar))
- Improved the rounding of `PodTopologySpread` scores to offer better scoring when spreading a low number of pods. ([#107384](https://github.com/kubernetes/kubernetes/pull/107384), [@sanposhiho](https://github.com/sanposhiho))

- Kube-apiserver: events created via the `events.k8s.io` API group for cluster-scoped objects are now permitted in the default namespace as well for compatibility with events clients and the `v1` API ([#100125](https://github.com/kubernetes/kubernetes/pull/100125), [@h4ghhh](https://github.com/h4ghhh))

  * The oidc client plugin has reduce round trips and fix scopes requested ([#45317](https://github.com/kubernetes/kubernetes/pull/45317), [@ericchiang](https://github.com/ericchiang))

* Admission webhooks rules can now limit scope to only match namespaced, or only cluster-scoped resources with a `scope: "Cluster" | "Namespaced" | "*"` field. ([#74477](https://github.com/kubernetes/kubernetes/pull/74477), [@liggitt](https://github.com/liggitt))
