GKE now supports concurrent node pool upgrades for clusters (Preview).

GKE now supports concurrent node pool upgrades for clusters (Preview). By default, GKE automatically upgrades one node pool at a time. To decrease the total time required to upgrade your cluster, you can now configure the maximum number of node pools that GKE auto-upgrades simultaneously. This feature is supported for both Standard and Autopilot clusters. For more information, see Configure concurrent node pool upgrades.
