- 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]

### API Change

- Kubelet podresources API now provides the information about active pods only. ([#79409](https://github.com/kubernetes/kubernetes/pull/79409), [@takmatsu](https://github.com/takmatsu)) [SIG Node]
- Pod Finalizers and Conditions updates are skipped for re-scheduling attempts ([#91950](https://github.com/kubernetes/kubernetes/pull/91950), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- When updating a CRD, per-expression cost limit check are now skipped for `x-kubernetes-validations` rules of versions that are not mutated. ([#121460](https://github.com/kubernetes/kubernetes/pull/121460), [@jiahuif](https://github.com/jiahuif))

* Fix public IP not found issues for VMSS nodes ([#80703](https://github.com/kubernetes/kubernetes/pull/80703), [@feiskyer](https://github.com/feiskyer))
* Fix a conformance test that was skipped when client had a newer micro version than server. ([#80598](https://github.com/kubernetes/kubernetes/pull/80598), [@smarterclayton](https://github.com/smarterclayton))

#### **Kubeadm**

 - Fixed the behavior of the `KUBE_PROXY_NFTABLES_SKIP_KERNEL_VERSION_CHECK` environment variable in the nftables proxier. The kernel version check is now skipped only when this variable is explicitly set to a non-empty value. To skip the check, set the `KUBE_PROXY_NFTABLES_SKIP_KERNEL_VERSION_CHECK` environment variable. ([#130401](https://github.com/kubernetes/kubernetes/pull/130401), [@ryota-sakamoto](h...

- Pod Finalizers and Conditions updates are skipped for re-scheduling attempts ([#91298](https://github.com/kubernetes/kubernetes/pull/91298), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- Skipped pod backoff entirely when the `PodMaxBackoffDuration` kube-scheduler option was set to zero and the `SchedulerPopFromBackoffQ` feature gate was enabled. ([#131965](https://github.com/kubernetes/kubernetes/pull/131965), [@macsko](https://github.com/macsko))...

- Fixed a 1.26 regression scheduling bug by ensuring that preemption is skipped when a PreFilter plugin returns `UnschedulableAndUnresolvable` ([#119952](https://github.com/kubernetes/kubernetes/pull/119952), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
