Thanks, fixed :)

Well those are version 1, of second/third revision of unstable protocols.

[rano-oss]

Agreed, but I think most people refer to the revisions _('')/
ref: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/39#implementation-matrix
Maybe have both?

[elinorbgr]

Yeah, maybe have a column "protocol revision", and a column "global version" ?

[PolyMeilex]

Yep, will do that

wl_compositor v5, subcompositor v1

[orowith2os]

Should the KDE SSD and virtual-keyboard-v1 protocols be supported still? We have xdg-decoration and the v2 of the virtual keyboard protocols already.

If clients don't support them, it would probably be better to fix the clients than work around their issues.

[Drakulix]

Especially kde-decoration is incredibly small and not really a maintenance burden, but (funnily enough) GTK of all toolkits has not yet moved to xdg-decoration.

There is an open PR to fix that, but that one hasn't received attention in years...

[orowith2os]

For readers: I've made a PR upstream to fix the issue, and in the process, caused the world to burn:
