There is a significant difference between 0.9.8 and 0.9.9 with at least Canon DSLR (CR3) scans with the default settings. With 0.9.8 colors are correct with default settings as long as properly cropped and/or sometimes adjusting Analysis buffer. With 0.9.9 with exactly the same settings, and even pre-cropped externally the resulting image goes either yellow or blue, occasionally even clipping in those channels.
