Fedora developer Ray Strode recently posted to the Fedora Developers list with the news that Wayland is now used by default when you log into GNOME with Fedora Workstation.  Previously to try out Wayland with Workstation, there was an additional session in the login screen that allowed you to choose either login with Xorg or Wayland. This change is part of the much anticipated proposed Fedora 24 feature, Wayland by Default. 

Ray also noted that, as the Change is still proposed, if Wayland by default doesn’t pan out, or the change doesn’t get approved rawhide will be switched back to having both sessions.

Ray also noted:

“But it’s good to get this in rawhide now, so we can get as much
exposure as possible to potential Wayland problems and get them fixed up before release.”

So if you use Rawhide, test away and file bugs!
