+- **Service Monitoring - Resource Utilization Dashboard**  
+  The CPU utilization and memory utilization metrics display will change to show the maximum utilization metric during a particular time period to better surface instances of underprovisionment, from average.
+  In addition, the CPU utilization metric will show a kubernetes-level CPU utilization metric which more closely resembles the metric used by ClickHouse Cloud’s autoscaler. 
+- **External Buckets**  
+  ClickHouse Cloud now lets you export backups directly to your own cloud service provider account.
+  Connect your external storage bucket - AWS S3, Google Cloud Storage, or Azure Blob Storage - and take control of your backup management.

 - [ClickHouse Cloud Azure Private Link](/cloud/security/azure-privatelink) has switched from using Resource GUID to Resource ID filters for resource identification. You can still use the legacy Resource GUID, which is backward compatible, but we recommend switching to Resource ID filters. For migration details see the [docs](/cloud/security/azure-privatelink#obtaining-private-endpoint-resourceid) for Azure Private Link.
