There aren't any gameplay or rule changes in that version. Here's the change log:

Version: 1.60 - SEP 22 2003
(Changes From 1.50)
Incorporate the final version of XINA (1.19) which fixes the problem
where booting the system with the power driver board disconnected
can cause factory reset to occur due to the mismatch of the last
country dipswitch setting in CMOS vs. the country setting for
an open power driver board cable.

I personally wouldn't worry about it, but that's just me. I'm pretty sure it's also "pub card only".
