Its nice to finally get the ISO out, the team are all relieved to finally be able to shift focus.
We do not give ETAs but with kernel 6.3.13 released a few days ago and being the last in the 6.3.x series I suspect it would not be too far away.
Plasma has had Wayland support enabled on Solus for a long time (I am using it now). The team are looking to enable it for Gnome as well with the next gnome stack update.
The team has also been working on improving the OTTB experience for Wayland such as having nvidia-drm.modeset=1
kernel parameter set by default for users on the proprietary nvidia drivers, which was planned for Solus 4.4 but the change had to be reverted due to issues found in testing. With Solus 4.4 out the door we can return to looking at stuff like this, such as enabling pipewire
by default which is required for certain things to work properly under Wayland. That said you don't need to wait and can switch to pipewire
manually should you wish, I am already using it as are many others and kernel parameters can be set manually also if you require them.
