For more information, see [About GKE Pod snapshots](https://docs.cloud.google.com/kubernetes-engine/docs/concepts/pod-snapshots). ## Feature Feature In GKE Standard clusters, [live migration](https://docs.cloud.google.com/compute/docs/instances/live-migration-process)is now supported on Confidential GKE Nodes that use [C3D machine series](https://docs.cloud.google.com/compute/docs/general-purpose-machines#c3d%5Fmachines)with [AMD SEV](https://docs.cloud.google.com/confidential-computing/confidential-vm/docs/confidential-vm-overview#amd%5Fsev)enabled. ## Fix Fixed A fix is available for an issue that caused incomplete file reads and premature end-of-file (EOF) errors when you used the Cloud Storage FUSE CSI driver on ARM64 nodes that use 64 KiB page sizes, such as A4X and A4X Max instances. This issue occurred because the kernel read-ahead mechanism triggered read requests that exceeded the capacity of the Cloud Storage FUSE layer. To resolve this issue, upgrade your cluster to one of the following versions: * 1.33.11-gke.1019000 or later * 1.34.6-gke.1154000 or later * 1.35.2-gke.1485000 or later
