 <Callout variant="important">
         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.

+
+Effective Wednesday, November 15, 2023, our Kubernetes integration drops support for Kubernetes v1.23 and lower. The Kubernetes integration v3.20.0 and higher will only be compatible with Kubernetes versions 1.24 and higher. For more information, read this note or contact your account team.
+
+## Background [#bg]
+
+Enabling compatibility with the latest Kubernetes versions and adding new features to our Kubernetes offering prevents us from offering first-class support to versions v1.23 and lower.
+
+## What's happening [#what's-happening]
+
+* Most major Kubernetes cloud providers have already deprecated v1.23 and lower.
+
+## What do you need to do [#what-to-do]
+
+It's easy: [Upgrade your Kubernetes clusters](/docs/integrations/kubernetes-integration/installation/kubernetes-installation-configuration#update) to a supported version.
+
+## What happens if you don't make any changes to your account [#account]
+
+The Kubernetes integration may continue to work with end-of-lifed versions. However, we can't guarantee the quality of the solution as new releases may cause some incompatibilities.
+
+Please note that we won't accept support requests for these versions that have reached the end of their life.
