And now the last blocker for @GIMP RC2 has been merged! 🥳
It's code by @pippin for a new "Perceptual" blend space for layer modes (in fact the old "perceptual" blend space was rather a "use image's profile curves" blend space so it was renamed to "RGB (from color space)"). It fixes some layer modes where the algorithm was rather expecting the input to be perceptual.
We are **very** close to a new release candidate! 🎅
