Wayland is the Linux graphical protocol for now and the future. At this point, there is no going back (nor is there a reason to, because Wayland is a vast improvement over X11). The migration from X11 to Wayland has been long and (at times) challenging. Fortunately, it looks as though the dust has settled and Wayland has the full support of most desktops and distributions.
System76's Pop!_OS seems to be one of the more popular Ubuntu remixes among tech-savvy Linux enthusiasts. That may mean that the bolder of them are about to break their computers, because finally, the beta of version 24.04 is here, along with the beta version of the company's COSMIC desktop. The version number is because this release is based on Ubuntu 24.04, aka "Noble Numbat," which was emitted by Canonical at the end of April 2024.
GNOME is a Linux desktop environment that you either love or hate. I've used GNOME and GNOME-based desktops for years and have always fallen on the side of "love." With each new release, I always find a feature or two (or a bit of extra polish) that makes me smile. The release of GNOME 49 is no different. Although there might not be any game-changing features for this release (I'm guessing the developers are holding out until the big 5-0), there's just enough to make it a worthy upgrade from 48.
