From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What does 4 bring that is good?

GPU acceleration and much more modern UI design (no gradients, flat elements, no shadows and worse contrast). It also has a lot of limitations and deprecations compared to GTK3 but we're not talking about that. The app doesn't seem to use the official libadwaita theme though which is a shame because I love it

why dont we? what are the limitations?

I'm not that advanced to give you a good answer here but basically some UI and backend elements from GTK3 don't exist in GTK4 and the last one has more limited theming support. The biggest issue is probably the random deprecation and breakage of older things during minor updates of GTK4. This all makes devs use GTK3 instead and not upgrading to GTK4. It's old, stable and feature-rich

Note: much of the benefits and downsides of gtk4 you mentioned are actually libadwaitas up and downsides.

[–] [email protected] 2 points 5 months ago

Well sorry. I'm not a backend dev

This is misleading. GTK4 is very themable.

However many projects use libawaita which forces a specific style, in order to design a complex and well integrated UI.
