If any `PreBindPreFlight` returned `Success`, the scheduler put NominatedNodeName to the pod 
  so that other components (such as the cluster autoscaler) could notice the pod was going to be bound to the node. ([#133021](https://github.com/kubernetes/kubernetes/pull/133021), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling and Testing]

- Kube-controller-manager: the `horizontal-pod-autoscaler-upscale-delay` and `horizontal-pod-autoscaler-downscale-delay` flags have been removed (deprecated and non-functional since v1.12). ([#124948](https://github.com/kubernetes/kubernetes/pull/124948), [@SataQiu](https://github.com/SataQiu)) [SIG API Machinery, Apps and Autoscaling]...

- The scheduler now clears the `nominatedNodeName` field for Pods upon scheduling or binding failure. External components, such as Cluster Autoscaler and Karpenter, should not overwrite this field.

- Enabled `kube-controller-manager` to support '--concurrent-horizontal-pod-autoscaler-syncs' flag to set the number of horizontal pod autoscaler controller workers. ([#108501](https://github.com/kubernetes/kubernetes/pull/108501), [@zroubalik](https://github.com/zroubalik))
