Changelog available here.
I'd prefer we update wayland-protocols first. If you want to provide a patch for this, that'd work for me. Otherwise, I can look into updating it this weekend to unblock this patch. Would prefer we don't regress in Wayland support, even if Wayland support for Solus still remains pretty much non-existent.
I attempted to patch the versioning file to force it to allow 1.16, but it looks like it actually uses features from 1.17. Guess it'll need a wayland-protocols update after all. I'll leave it to you.
