GTK+ 3.22.4 is now the latest stable and most advanced version of the GUI toolkit, which is the core of the GNOME desktop environment. This version is released for the GNOME 3.22.x desktop series, and it looks like it adds many improvements for the next-generation Wayland display server. The biggest changes being the fact that GTK+ now uses less CPU under Wayland than under X11, which means that we’re a step closer to having Wayland by default on our favorite GNU/Linux distributions. Fedora 25 launches tomorrow, and it looks like it’s the first major distro to ship with Wayland by default for the GNOME/Workstation edition.
