Oh thank god, this is the first I’ve heard of them working on GAMMA_LUT support. I’ve been dying without night light.
Well, they haven’t committed to a release number and I don’t know what priority the ticket has, however if you use KDE there will be a workaround for night light without GAMMA_LUT for Plasma 6.
