• Adds driver to install media to allow OS installation on LSI 12GB/s SAS HBA's.

Hardware Controllers

• Fix for Adaptec controllers to correctly report Cache Policy and Battery Backup Property.

Network Shares

• Adds filtering for NFS Network rules to ensure that host and IP NFS export entries are before network or domain rules. This allows for more complicated rules such as read only access for all hosts on a network and read/write access for a specific host on the same network.
• Enhancements to the CLI for the qs share-modify user access list management, the new system allows for specifying just the username or group name or list option that you would like to add or remove, reducing the number of flags required to be passed in on an individual share modification.

	[--user-access-list] :: List of users with permission to access the network share for example
	                            'user1:valid,user2:invalid,user3:none,~user7,~user33', prepend with tilde
	                            (~) to remove fields/properties.
	[--group-access-list] :: List of groups with permission to access the network share for example
	                            'group1+DOMAIN:valid,~group2+DOMAIN' prepend with tilde (~) to remove
	                            access for specific users or groups.
	[--cifs-options] :: CIFS/Samba configuration options specified as
	                            'key=value,key2=value2,~key3,...', prepend with tilde (~) to remove
	                            fields/properties. 

• Removed redundant CIFS service restart when snapshots are taken. This resolved a temporary timeout that would occur on CIFS network shares when files where accessed via a stream, for example music or video files.
• Adds logic to ensure a rename of a Network Share on a ZFS Storage Pool with active clients will raise an alert and be canceled early, not affecting the active client connections.

Storage Volumes

• Adds support for modifying Thin/Thick provisioning(referenced capacity) for Storage Volumes
• Adds support for fast coordinated VSS snapshots for upcoming VSS plugin.

Scale-out File Storage

• Enhanced the Gluster Create High-Availability Virtual Interface Dialog to show member nodes of the Specified Gluster Volume.
