- HPA controller starts to expose metrics from the kube-controller-manager.\n- `reconciliations_total`: Number of reconciliation of HPA controller. \n- `reconciliation_duration_seconds`: The time(seconds) that the HPA controller takes to reconcile once. ([#116010](https://github.com/kubernetes/kubernetes/pull/116010), [@sanposhiho](https://github.com/sanposhiho))

- Promoted HPA configurable tolerance to beta. The `HPAConfigurableTolerance` feature gate has now been enabled by default. ([#133128](https://github.com/kubernetes/kubernetes/pull/133128), [@jm-franc](https://github.com/jm-franc)) [SIG API Machinery and Autoscaling]...

- Graduated `ImageVolume` feature to stable. ([#136711](https://github.com/kubernetes/kubernetes/pull/136711), [@saschagrunert](https://github.com/saschagrunert)) [SIG Apps, Architecture, Node and Testing]
- HPA: Improved scaling to and from zero with enabled HPAScaleToZero feature gate. ([#135118](https://github.com/kubernetes/kubernetes/pull/135118), [@johanneswuerbach](https://github.com/johanneswuerbach)) [SIG Apps, Autoscaling and Testing]

* When HPAScaleToZero feature gate is enabled HPA supports scaling to zero pods based on object or external metrics. HPA remains active as long as at least one metric value available. ([#74526](https://github.com/kubernetes/kubernetes/pull/74526), [@DXist](https://github.com/DXist))
    * To downgrade the cluster to version that does not support scale-to-zero feature:

- Added HPA support to pod-level resource specifications. When the pod-level resource feature was enabled, HPAs configured with `Resource` type metrics calculated the pod resources from `pod.Spec.Resources` field, if specified. ([#132430](https://github.com/ku...

   ([#123492](https://github.com/kubernetes/kubernetes/pull/123492), [@carlory](https://github.com/carlory))
- Added metric name along with the utilization information when running `kubectl get hpa`. ([#122804](https://github.com/kubernetes/kubernetes/pull/122804), [@sreeram-venkitesh](https://github.com/sreeram-venkitesh))
