# Alluxio Kubernetes Operator 3.4.3 Release Notes

## Summary

### Major Enhancements

* **CSI FUSE sharing** lets one shared FUSE pod serve multiple PVCs that use the same volume key, reducing the number of FUSE workloads you run.
* **Under storage credentials** are refreshed when their Kubernetes Secret changes.

### Bug Fixes

* **FUSE deployment and cleanup** are more reliable for DaemonSet deployments and CSI mount-point cleanup.
* **Coordinator service compatibility** is restored for affected deployments.

## Breaking Changes

* FUSE pod naming and staging have changed. Multiple PVCs with the same volume key now share one FUSE pod instead of each PV using its own FUSE pod.

## Upgrade Notes

* Update monitoring, automation, and troubleshooting procedures that assume one FUSE pod per PVC or PV.
* After upgrading, validate CSI-backed workloads that depend on FUSE pod names or staging behavior.
