These new 3.6.8.1410 drivers seem good to me. The lowest hardware buffer sample size is 64 now, and the ASIO output routing offset problem is fixed in this new release.
Also, there are 3 new software tools in CueMix FX under the Device Menu: Oscilloscope, X-Y Plot, and Phase Analysis. And unlike the Oscilloscope (which didn't work for me) that was part of the 3.6.8.1400 driver release, all 3 of these new tools work!

EDIT:
I didn't think to post this with my original post, but the trim knobs on the Input tab of CueMix now work in correspondence with the trim knobs on the hardware. If the trim knobs on the hardware is adjucted, the trim knobs on CueMix move simultaneously. Cool!
Also, when I turn on my UltarLite MK3, it shows Loading Audio Router..., when it used to read Loading Audio Console....
