Version History for the Operating System in Roland HPD-15

I've posted this same information to the Roland HandSonic Yahoo Group , too.

I e-mailed the Finnish Roland tech support asking what was fixed in the OS version 1.06. I got the version history since 1.04 and they responded within a few hours. I was also told that version 1.04 is the first public update to the initial v 1.0 release. And I used to say Roland tech support was bad :)
Anyway, here's the info:

Version 1.0:

Version 1.04:

Version 1.05:

Version 1.06:
