Yep you read that right, we’ve decided to throw the lever and go Wayland by default! The three remaining showstoppers are in the process of being fixed and we expect them to be done soon–certainly before the final release of Plasma 6. So we wanted to make the change early to gather as much feedback as possible.
Excellent news. Of course, distributions will still be able to opt for the unmaintained, deprecated X.org if they want to, but most distributions will opt for Wayland, as all the major ones have been doing for a while now.
