What’s New for Tenants

This quarter brings several changes that directly affect your workloads:

Kubernetes v1.33: The cluster has been upgraded to Kubernetes v1.33. Check the Kubernetes 1.33 release notes for new features, deprecations, and API changes that may affect your workloads.
New GPU Node Groups: NVIDIA L40S 48Q and L40S 12Q are now available. GPU nodes now use the taint nvidia.com/gpu.product, allowing you to request access to specific GPU types. The previous generic taint role.node.kubernetes.io/worker-vgpu has been removed.
Ephemeral Volumes: You can now use Ephemeral Volumes in your workloads – useful for caches, temp files, or scratch data that doesn’t need to persist.
vCluster Example: We added documentation on how to run a vCluster within your namespace for isolated testing or development environments.

Under the Hood

Cluster-API, CAPO, and the OpenStack Cloud Controller Manager were updated to match the new Kubernetes version. The base OS was updated to AlmaLinux 10. Graceful Node Shutdown was configured to improve stability during node updates and OpenStack maintenance.
