AppleShare Workstation 3.6.1 RevB & 3.6.1: Differences

I have installed AppleShare Workstation 3.6.1, now after installing System 7.5 Update 2.0 the AppleShare Workstation version is now 3.6.1RevB. What is the difference between 3.6.1 and 3.6.1RevB and which one should I use.
The only difference between AppleShare Workstation 3.6.1 and 3.6.1RevB is the bundle bit is set on the 3.6.1RevB and is not set on the 3.6.1.

You should use AppleShare Workstation 3.6.1RevB.
