Deconvolving in SpaceDesigner: it's still there
Deconvolving in SpaceDesigner/L8 is no longer visible in the GUI, but you can access it from the corntrols-view; it's somewhere in the right colomn.
Excellent, this is a much more flexible method than using the IR Utility from what I understand. It seems to me that the IRU only allows you to deconvolve sounds that were recorded in it, though I may of course be wrong.
