Workgroup Server 9650: Jackhammer Control Panel

The Jackhammer control panel v 1.2.2 comes with the Workgroup Server 9650 and 7.6.1. Hammer's web site has version 1.3 posted. Should I update to 1.3?
The Jackhammer 1.3 control panel is untested and therefore unsupported. You should continue to use version 1.2.2 with a 9650 and MacOS 8.x
