 ## Current Release
 * Added ResourceGroup Completer to -ResourceGroup parameters allowing tab completion through resource groups in current subscription
+* Added -UseOriginalStorageAccount option to the Restore-AzureRmRecoveryServicesBackupItem cmdlet. 
+	- Enabling this flag results in restoring disks to their original storage accounts which allows users to maintain the configuration of restored VM as close to the original VMs as possible. 
+	- It also helps in improving the performance of the restore operation.
 
 ## Version 4.0.3
 * Fixed bug - Get-AzureRmRecoveryServicesBackupItem should do case insensitive comparison for container name filter.
