GTK 2 has been EoL since 2020 (GTK 3 released in 2011). GIMP 3 marks the completion of the GTK 3 port, which by itself offers:
- Moving to an actively supported version of GTK (and future migrations will be easier because the difference between 3 and 4 is a lot less than the difference between 2 and 3)
- Better graphics tablet support
- Better handling of HiPPI displays
- Better Wayland support
- Should also mean that they finished refactoring the code, thus making it easier to implement new features.
And on that last point, I would say that the biggest benefit overall with the release of GIMP 3 is that we’ll finally, finally start seeing serious work on implementing non-destructive editing; I’ve read that some of the preliminary work is going to be shipping with the 3.0 release.
It’s because they’d have to install it to use it. I put my boomers on Fedora with GNOME over a year ago and there hasn’t been a single Linux-related issue since. Most people use their computers as Facebook and YouTube machines and Linux doesn’t make that any harder than Windows/MacOS. It’s not like it’s 2010 where you’d need to install some desktop app that doesn’t have a Linux version and you’d have to fuck around with WINE, which was a massive pain in the ass and often buggy even if it did work. Now in 2024, those apps are in the browser (barring more niche use-cases) and we have access to Firefox and Chrome like everyone else. If Linux shipped on most pre-builts, then I think the average person would be fine.
