Aside from being based on Fedora 39 now, KDE is now the official desktop environment replacing GNOME. The reasons why are in the article.
The GNOME version of Nobara still exists, but it's going to be the vanilla version shipped without any extensions (probably because many of them broke after moving to Fedora 39)
Interesting to read those linked GNOME issue threads, they're really living up to their reputation... Looks like KDE is becoming the premier gaming DE, and I'm pretty happy with that.
I switched from GNOME to KDE half a year ago precisely because GNOME merge requests for important features constantly end up in limbo for years. KDE announcing initial HDR support for next year was just the final nail in the coffin.
Also appindicators still do not work out of the box in GNOME while it is an essential feature for many applications.
As I understand it, that's not even needed because the current DE choice is being preserved at an upgrade. The only thing that needs manual tweaking is reinstalling the extensions from the Gnome website which isn't really an issue at all.
I know reading is hard but you realize this quote was reason #5 of the many reasons listed... I'm not going to copy-paste the article, it's all relevant info.
