Changes to black compression and saturation controls. Black compression from 0-50 acts the same as 0-100 on the previous version, compressing dark tones without crushing blacks. 50-100 then starts crushing blacks until by 100 on the slider, all tones up to the set black point are sent to zero. In the new saturation control, negative values of the slider set a linear curve rather than an inverted S curve, and smoothly decrease saturation to zero across the board.
