New icons and more bug fixes. Supposed to be faster yet again. Probably some more wee little tweaks here and there. Weird that there is not much info out on the web for the various AKUs, isn't it?
Best info I can find is on "crossbow" (WM6)

And the comment that AKU3.5 includes many of the crossbow GUI changes without the underlying OS changes introduced in WM6
