Lee, since Wolfram is going to apply patches 1 and 5, how could we proceed with the rest? Patches are indeed build independent, though they are unified by enabling logically piece-by-piece. It would be great if you think you may apply them to your v4.4 queue. > This patch series dedicated to enable those devices.
