I’ve been in the habit of downloading a new RT appimage every few days, especially as the film negative tool is progressing so quickly. Right now, however, the latest appimage that I find is still from January 21, 2021. Am I on the right download link? https://github.com/Beep6581/RawTherapee/releases/tag/nightly
The appimage is still stuck on Jan. 21, now 5 weeks behind the Windows version.
