# Alluxio Kubernetes Operator 3.5.1 Release Notes

## Summary

### New Features

* **Ephemeral CSI volumes** are now available for FUSE workloads.

### Major Enhancements

* **Shared FUSE pods** are created for new CSI volumes whenever possible, reducing the number of FUSE workloads you run.

## Breaking Changes

## Upgrade Notes

* After upgrading, validate both new and existing CSI-backed workloads.
* Update automation that expects new volumes to use the v1 FUSE pod model.
