Support for Virtual Clusters
Virtual frontends and virtual compute nodes are now supported. The network for a VM frontend its VM compute nodes are contained within its own VLAN.
A virtual cluster is added with "rocks add cluster fqdn=X ip=Y num-computes=Z". See "rocks add cluster help" for details.
Can build rolls outside of Rocks source tree.
All roll building support files are under /opt/rocks/share/devel.
Can reconfigure a compute node's network without rebooting.
Rocks commands were added to support this. See the documentation for the procedure.
Distribution moved to /export/rocks/install.
No longer require NFS on the frontend to properly host a Rocks Distribution. This will make moving user accounts to an external NFS server easier.
Fine-grained control over the "boot" and "install" kernel for Xen VMs.
Rocks commands where added to support this feature. For details, execute: "rocks help installprofile" and "rocks help bootprofile".

Base: Added "rocks remove roll" command. Thanks to Brandon Davidson from the University of Oregon for the code.
Base: The command "rocks-dist" is replaced with "rocks create distro".
Base: Disabled the watchdog for frontend installs that boot off a CD/DVD.

Area51: All commands converted to Rocks command line.
HPC: Updated OpenMPI to v1.2.7.

Restore: All files under /export/rocks/install/contrib are now included in the Restore Roll.
Restore: All files in /var/named/*local are now included in the Restore Roll.
Restore: The frontend's ssh machine keys are now included in the Restore Roll.
SGE: Updated to v6.1 update 5.
SGE: Added a script to reinstall a cluster by submitting an SGE job.
Base: Reverse domain lookups now work for subnets that don't fall on an octet boundary.
Base: Bootflags now carry over between reinstallations and reboots. In the previous release, a reboot would "forget" the bootflags set by the user with the Rocks command line.

Restore: Ethernet Switches, Power Units and Remote Management appliances are now properly saved in the Restore Roll.
Ganglia: Fixed the 'tail +4' bug in the cron job.
