The current release 5.22 of KDE Frameworks gained a new framework: KWayland. So far KWayland got released together with Plasma. KWayland entered as tier 1/integration and is only available on Linux (and other Linux-like systems).
For us working on the Wayland stack in Plasma and KDE this is a very important step. Now we can use KWayland also in other frameworks. Also with KWayland in frameworks we expose it to a larger audience. We hope that it is a useful framework for anyone using Wayland with Qt. It’s not a replacement for QtWayland, rather an addition and way more flexible by being closer to the Wayland API.
This change is also important for distributions. Please note that this is only a logical move in the project structure. KWayland 5.22 is fully ABI compatible to the last release 5.6. You can just exchange the KWayland from Plasma with the one in frameworks. Plasma 5.6 of course works perfectly fine with KWayland 5.22.
