Hmm, they did finally update the CCPassport software - amazing!
Here's what the X-Rite site says:
"New in release 1.1.0
Compatible with Adobe® Photoshop® Lightroom® 6.1
Support for DNG images larger than 40mb
New in release 1.1.1
Addition Korean Language support"
Sounds like it will handle 645z files, maybe Nikon D810 & Sony Alpha as well. They have removed the old site's central software downloads page though, so you really have to poke around to find the current d/l.
BTW, I'll probably have to try it just to satisfy my curiosity, but right now Lumariver Profile Designer is working great for me. Nice results right away for my 654z, next up are Canon & Fuji...
