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

## Feature Feature 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](https://cloud.google.com/kubernetes-engine/docs/how-to/upgrading-a-cluster#concurrent-upgrades). ## Feature Feature Managed OpenTelemetry on GKE now supports the collection of multimodal prompts and responses (Preview) for LangGraph and Agent Development Kit (ADK) agents. You can view and analyze the data in the Trace Explorer and BigQuery platforms. For more details, see [Collect multimodal prompts and responses data](https://docs.cloud.google.com/kubernetes-engine/docs/how-to/managed-otel-gke#multimodal-prompts-responses). ## Change Change Container-Optimized OS (COS) milestone 129 and higher no longer include the`kubectl` binary in the `/usr/bin/` directory.
