I took the plunge and upgraded to 1.0. Managed to get there via some issues with netatalk and the nut/rdd graphing, able to resolve these from the useful forum posts .. thanks all 
Only issue I can see is a regression in the smartctl information from USB disks attached. When requesting the SMART information via the OMV GUI, you get this error:
Code
Failed to get S.M.A.R.T. self-test logs (device=/dev/sdf): smartctl 5.41

/dev/sdf: Unknown USB bridge [0x1058:0x1230 (0x1050)]
Smartctl: please specify device type with the -d option.
Use smartctl -h to get a usage summaryIt seems the "-d sat" option is possibly missing off the smartctl call?
Code
ianch-hp ~: sudo smartctl -a /dev/sdf -d sat | head -20
