This update adds the ability to choose between seven intermediate color spaces: CAM02-UCS, CAM02-LCD, CAM02-SCD, CIELab, sRGB, sRGB linear, and XYZ. CAM02-UCS remains the most effective and recommended choice, but it's slower than using sRGB directly, and other color spaces provide unique results.
Also new in this update is a "halftone" ordered dithering mode, which will produce a checkerboard pattern.
