GKE capacity buffers generally available on Standard and Autopilot, version 1.37.1-gke.3020000+

Capacity buffers, including active and standby capacity buffers, are generally available for GKE Standard and Autopilot clusters running version 1.37.1-gke.3020000 or later. Capacity buffers let you pre-provision and optionally suspend standby compute capacity using the CapacityBuffer custom resource (autoscaling.x-k8s.io/v1beta1) to accelerate workload scaling and mitigate capacity constraints. To get started, see About capacity buffers.
