- Previously, the scheduling queue didn't notice any extenders' failures, potentially resulting in missed cluster events and Pods rejected by Extenders being stuck in the unschedulable pod pool for up to 5 minutes in the worst-case scenario. Now, the scheduling queue notices extenders' failures and requeues Pods rejected by Extenders appropriately.

- Print NotReady when pod is not ready based on its conditions. ([#88240](https://github.com/kubernetes/kubernetes/pull/88240), [@soltysh](https://github.com/soltysh)) [SIG CLI]
- Scheduler Extender API is now located under k8s.io/kube-scheduler/extender ([#88540](https://github.com/kubernetes/kubernetes/pull/88540), [@damemi](https://github.com/damemi)) [SIG Release, Scheduling and Testing]

- Rename PluginContext to CycleState in the scheduling framework ([#83430](https://github.com/kubernetes/kubernetes/pull/83430), [@draveness](https://github.com/draveness))
- Some scheduler extender API fields are moved from `pkg/scheduler/api` to `pkg/scheduler/apis/extender/v1`. ([#83262](https://github.com/kubernetes/kubernetes/pull/83262), [@Huang-Wei](https://github.com/Huang-Wei))

   - `.extenders` are updated to satisfy API standards. In particular:
     - `.extenders` decoding is case sensitive. All fields are affected.
     - `.extenders[*].httpTimeout` is of type `metav1.Duration`.
     - `.extenders[*].enableHttps` is renamed to `.extenders[*].enableHTTPS`.
