Latest release failed the tests (with some memory corruption yikes) even. Doesn't inspire a lot of confidence that it won't eat your photos.
But the v7 uses DNN from OpenCV for face detection that supposedly has 91% accuracy on CPLFW which is pretty good! So how come people here say it sucks?
I'm away from my desktop computer, but it wasn't half bad when I last updated its DB. I don't take much portraits, so I don't use that feature much, but give it a look when I can and update you.
