- PersistentVolumeLabel admission plugin, responsible for labeling `PersistentVolumes` with topology labels, now does not overwrite existing labels on PVs that were dynamically provisioned. It trusts the  dynamic provisioning that it provided the correct labels to the `PersistentVolume`, saving one potentially expensive cloud API call. `PersistentVolumes` created manually by users are labelled by the admission plugin in the same way as before....

- kube-dns is deprecated and will not be supported in a future version ([#86574](https://github.com/kubernetes/kubernetes/pull/86574), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

          You gave us three or more;
        They all returned from him to you,
          Though they were mine before.

        If I or she should chance to be
          Involved in this affair,
        He trusts to you to set them free,
          Exactly as we were.

        My notion was that you had been
          (Before she had this fit)
        An obstacle that came between
          Him, and ourselves, and it.

      * Open API now includes strategic merge patch tags (previously only in go struct tags) ([#44121](https://github.com/kubernetes/kubernetes/pull/44121), [@mbohlool](https://github.com/mbohlool))

### API Change

- Added `omitempty` and `opt` tag to the API `v1beta2` AdminAccess type in the `DeviceRequestAllocationResult` struct. ([#132338](https://github.com/kubernetes/kubernetes/pull/132338), [@PatrickLaabs](https://github.com/PatrickLaabs))

- Introduced a breaking change to the `resource.k8s.io` API in its `AllocationResult` struct. This change allows a kubelet plugin for the `DynamicResourceAllocation` feature to service allocations from multiple resource driver controllers. ([#116332](https://github.com/kubernetes/kubernetes/pull/116332), [@klueska](https://github.com/klueska))...

* Mark image as deliberately optional in v1 Container struct.  Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set. ([#48406](https://github.com/kubernetes/kubernetes/pull/48406), [@gyliu513](https://github.com/gyliu513))

- Scheduler extender filter interface now can report unresolvable failed nodes in the new field `FailedAndUnresolvableNodes` of  `ExtenderFilterResult` struct. Nodes in this map will be skipped in the preemption phase. ([#92866](https://github.com/kubernetes/kubernetes/pull/92866), [@cofyc](https://github.com/cofyc)) [SIG Scheduling]

* Fixes issue with cleaning up stale NFS subpath mounts ([#71804](https://github.com/kubernetes/kubernetes/pull/71804), [@msau42](https://github.com/msau42))
* Modify the scheduling result struct and improve logging for successful binding. ([#71926](https://github.com/kubernetes/kubernetes/pull/71926), [@wgliang](https://github.com/wgliang))
