Like a lot of the changes that we rolled into CT recently, it is fixing a pretty minor thing, that you might not notice. This one was actually brought up in these forums. This thread talks about the curves using the perceptual rendering intent for i1Profiler profiles. They were wacky, and now the curves are presented correctly.
Concerning your profile, the 3D graph looks very smooth so I doubt there is anything wrong with your profile. If you’re looking at the little magenta bump in the 2D projection, I don’t think that’s anything to worry about. Send me anything more you’d like me to check out.
