- Fixed EDITOR/KUBE_EDITOR with double-quoted paths with spaces when on Windows cmd.exe. ([#112104](https://github.com/kubernetes/kubernetes/pull/112104), [@oldium](https://github.com/oldium)) [SIG CLI and Windows]

For more information, see [#53040](https://github.com/kubernetes/kubernetes/issues/53040).

* Object quotas are not consistently charged or updated. Specifically, the object count quota does not reliably account for uninitialized objects. Some quotas are charged only when an object is initialized. Others are charged when an object is created, whether it is initialized or not. We plan to fix this issue in a future release.

### Source Code

* Moved qos to api.helpers. ([#44906](https://github.com/kubernetes/kubernetes/pull/44906), [@k82cn](https://github.com/k82cn))

* Fix issue with the resource quota controller causing add quota to be resynced at the wrong ([#45685](https://github.com/kubernetes/kubernetes/pull/45685), [@derekwaynecarr](https://github.com/derekwaynecarr))

*   A Pod can now listen to the same port on multiple IP addresses.  ([#52421](https://github.com/kubernetes/kubernetes/pull/52421),[ @WIZARD-CXY](https://github.com/WIZARD-CXY))
*   Object count quotas supported on all standard resources using count/<resource>.<group> syntax ([#54320](https://github.com/kubernetes/kubernetes/pull/54320),[ @derekwaynecarr](https://github.com/derekwaynecarr))

- You can now create a non-preempting Pod priority (NonPreemptingPriority). If set on a class, the pod will continue to be prioritized above queued pods of a lesser class, but will not preempt running pods. ([#74614](https://github.com/kubernetes/kubernetes/pull/74614), [@denkensk](https://github.com/denkensk))

The CustomCFSQuotaPeriod alpha feature enables node administrators to change the default period used to enforce CFS quota on a node.  This can improve performance for some workloads that experience latency while using CFS quota with the default measurement period.  Finally, the SIG continues to focus on improving reliability by fixing bugs while working out design and implementation of future features.

* Resource quotas on extended resources such as GPUs are now supported. ([#57302](https://github.com/kubernetes/kubernetes/pull/57302), [@lichuqiang](https://github.com/lichuqiang))
