Since upgrading to this version, but also after upgrading xserver-xorg-video-i810 to version 2:1.7.2-3, the brightness and contrast of the video are extreme, and there's no way to fix it with the monitor settings. However, going into Settings -> xine parameters -> video, and simply saying apply with whatever value is selected fixes the problem.
