 ## NFS support
 [NFS 4.1 support for Azure Files](https://azure.microsoft.com/en-us/blog/nfs-41-support-for-azure-files-is-now-in-preview/preview/) is now in Public Preview. This service is optimized for random access workloads with in-place data updates and provides full POSIX file system support. This page shows how to use NFS feature by Azure File CSI driver on Azure Kubernetes cluster.
 
-#### Feature Status: Alpha
+#### Feature Status: Beta
 > supported OS: Linux
 
-#### Supported CSI driver version: `v0.8.0`
+#### Supported CSI driver version: `v0.9.0`
+> storage account dynamic provisioning is supported from `v0.10.0`.
 
 #### [Available regions](https://aka.ms/azurefiles/nfs/preview/regions)
 We are continually adding more regions. Latest region list is available on [Azure NFS documentation](https://aka.ms/azurefiles/nfs/preview/regions)
