         Starting from Kubernetes version 1.26, the `@autoscaling/v2beta2` API is no longer available and replaced by the `@autoscaling/v2`. For continued `HorizontalPodAutoscaling` metric reporting it's important that you install `kube-state-metrics` version 2.7+ on the Kubernetes version 1.26+ clusters. This is because only `kube-state-metrics` v2.7+ can support the `@autoscaling/v2` API.
