Wel it depends what one considers firmware and what software.....
In my mind firmware is non user interface, but function part of an update.
Software is user interface update.
If you put it that way, then V31 (10.0) is going to update your firmware, since it is goingt to alow you to use DVD/DL disks, you wont se any Software change, so no software updates on this one. I belive that i was V27 that gave slightly diferent menus, that i would call software update.
