for wince I think it was 2.11 But for katana ones I've heard there are r12 or even r13, is that true? Or is it the r11 alpha the latest one? Anyonemight give me access to r12 or so docs?
I've heard of the rumored R12, but R11a is the only last one I know that's actually out there. I don't even know if anyone has the finalized version of R11.
There probably wouldn't be a lot different. Maybe support for new devices like the ZIP drive had it made it to production. The main difference in R11 is that it focuses a lot more on online gameplay with the included Gamespy documentation / include files.
