They messed up the resolution. No more "4x the resolution" as "retina" anymore for Apple devices, it seems. It's the end of that, as we've seen with the new iPhones.
So now developers will have to target those resolutions exactly as they are. No more "elegant scaling" and whatnot.

People writing MacOS software do not typically target a particular number of pixels; it's a windowed operating system. One point will be 2x2 pixels, as on the retina MBP and iMac, and on all retina iOS devices except the big iPhone (where one point is 3x3 pixels).
