 ## GCP
 
 * As of Kubernetes version 1.29, credentials for private GCR/AR repositories will be handled by the out-of-tree credential provider. This is an additional binary that each instance downloads from the assets repository.
+* Two additional `StorageClasses` are created on GCP clusters. These are called `balanced-csi` and `ssd-csi` and utilize the GCP Balanced and SSD Persistent Disk volume types respectively.
+* **Breaking Change** - the default `StorageClass` has been changed from `standard-csi` to `balanced-csi`.
