Probably the biggest change in the new release is the new Process Version. It represents a fundamental change in the way the software process images. Fill light, Recovery, and Brightness have all gone away. Instead, Adobe has opted to include four main sliders, Highlights, Shadows, Whites, and Blacks. You can still achieve the same basic effects, but you now have more control of which part of the image you affect with your adjustments. It takes a little getting used to, but the extra leeway it seems to offer in terms of preserving image information makes it worth it.
