This release is bad for 290/x owners.  Something is obviously different between this and the 2% fee miner, because this one crashes at intensity above 15 and the 2% fee one did not.  Unfortunately, I cannot use anything above -g 3 without getting Error -4, so I need the correct intensity setting to work to get a decent hash rate.

That makes this miner bad for 290 owners until the author fixes the intensity bug.  You will not get the 3.7mh+ on this miner until it is fixed.
