- When the cluster size is small and the scheduler doesn't get unscheduled Pods frequently, the scheduler doesn't try to reschedule Pods in some cases. ([#119784](https://github.com/kubernetes/kubernetes/pull/119784), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling and Testing]

## Known Issues

### The PreEnqueue extension point doesn't work for Pods going to activeQ through backoffQ

In v1.26.0, we've found the bug that the PreEnqueue extension point doesn't work for Pods going to activeQ through backoffQ. 
It doesn't affect any of the vanilla Kubernetes behavior, but, may break custom PreEnqueue plugins.

- Improved memory usage of `kube-scheduler` by dropping the `.metadata.managedFields` field that `kube-scheduler` doesn't require. ([#119556](https://github.com/kubernetes/kubernetes/pull/119556), [@linxiulei](https://github.com/linxiulei))
- In a scheduler with `Permit` plugins, when a Pod is rejected during `WaitOnPermit`, the scheduler records the plugin.

  Ginkgo V2 doesn't accept go test's `-parallel` flags to parallelize Ginkgo specs, please switch to use `ginkgo -p` or `ginkgo -procs=N` instead. ([#109111](https://github.com/kubernetes/kubernetes/pull/109111), [@chendave](https://github.com/chendave)) [SIG API Machinery,...

If you used to rely on this behavior, now you should create the resources for background tasks inside the background task itself, and use internally only data that doesn't depend on the resources of dependencies with `yield`.

    * Action required:
    * Anyone who generated server cert for admission webhooks need to regenerate the cert. Previously, when generating server cert for the admission webhook, the CN value doesn't matter. Now you must set it to the DNS name of the webhook service, i.e., `<service.Name>.<service.Namespace>.svc`.
