Two major features have been added:
A new cmdlet Invoke-NcSysstat which is like Invoke-NaSysstat and allows you to monitor cluster system performance stats for: System, FCP, NFSv3, NFSv4, CIFS, iSCSI, Volume, Ifnet, LUN, and Disk.
Invoke-NcSysstat works in both the cluster and Vserver context for Data ONTAP 8.2 and up. For Data ONTAP versions previous to 8.2, Invoke-NcSysstat must be run in the cluster context. Ifnet and Disk performance stats aren’t available when running against the Vserver context.
Invoke-NcSysstat can also aggregate performance stats for selected objects.
The following parameters have been added to the 7-mode cmdlet set:
- ConvertTo-NaVhd: FollowParent
 - ConvertTo-NaVhdx: FollowParent
 - Read-NaDirectory: Encode
 - Set-NaDiskOwner: All, DiskCount, DiskType
 - Start-NaClone: IgnoreStreams, IgnoreLocks
 
- The following parameters have been added to the clustered ONTAP cmdlet set:
 - Add-NcSnmpCommunity: VserverContext
 - Copy-NcLdapClientSchema: VserverContext
 - Get-NcNfsService: Query
 - Get-NcPerfInstance: VserverContext
 - Invoke-NcClusterHaTakeover: BypassOptimization, SkipLifMigration
 - New-NcClone: IgnoreStreams, IgnoreLocks, QosPolicyGroup
 - New-NcFlexcachePolicy: MetafilesTimeToLive, SymbolicTimeToLive, OtherTimeToLive, DelegationLruTimeout, PreferLocalCache, Vserver
 - New-NcLdapClient: VserverContext
 - New-NcUser: Comment
 - Read-NcFile: Stream
 - Remove-NcFlexcachePolicy: Vserver
 - Remove-NcLdapClient: VserverContext
 - Remove-NcLdapClientSchema: VserverContext
 - Remove-NcSnmpCommunity: VserverContext
 - Set-NcAutoSupportConfig: IsOndemandEnabled, IsOndemandRemoteDiagEnabled, OndemandServerUrl, OndemandPollingInterval, MinimumPrivateDataLength
 - Set-NcDiskOwner: All, DiskCount, DiskType
 - Set-NcFlexcachePolicy: MetafilesTimeToLive, SymbolicTimeToLive, OtherTimeToLive, DelegationLruTimeout, PreferLocalCache, Vserver
 - Set-NcLdapClient: VserverContext
 - Set-NcLdapClientSchema: VserverContext
 - Set-NcRoleConfig: MinPasswordSpecialCharacter, PasswordExpirationDuration, MaxFailedLoginAttempts, LockoutDurationDays, RequireInitialPasswordUpdate
 - Set-NcUser: Comment
 - Write-NcFile: Stream
 
Enhancements
- Get-NaVirtualDiskAlignment and Repair-NaVirtualDiskAlignment can now detect and repair alignment issues for both VHD and VHDX format disks.
 - Set-NaVirtualDiskSize now supports growing and shrinking VHDX format virtual disks.
 - The NDMP copy cmdlets (Start-NaNdmpCopy and Invoke-NaNdmpCopy) have been improved. The credentials cache will look up credentials based on the IP addresses and hostnames associated with the IP addresses. The DstController parameter is no longer a required parameter. If DstController is omitted, the SrcController is used as the destination.
 - Copy-NaHostFile will now offload the copy operation to Data ONTAP whenever cloning is not possible.
 - Show-NaHelp now displays help for aliased cmdlets in the clustered ONTAP online help documentation.
 
- Timestamp output sometimes not returned correctly for Get-NcPerfData.
 - Get-NaSnapmirrorConnection address pairs were missing for Data ONTAP 8.2.
 - Controller connection serialized then deserialized with ConvertTo-SerializedString and ConvertFrom-SerializedString would not initialize ONTAPI version properly.
 - Several of the “Related Links” in the online help documentation were broken.
 - SCSI unmap performance increase.
 - NDMP copy cmdlets (Invoke-NaNdmpCopy and Start-NaNdmpCopy) could hang if the source path does not exist.
 - Divide-by-zero error could occur in Get-NcEfficiency.
