Hello , also wanted to say great work and a huge thank you!! These are some amazing improvements 
I do have one question though — where did the “r.VXGI.Range” console command go? It doesn’t seem to appear and I can’t find it in the PP settings either.

It’s been replaced with r.VXGI.VoxelSize.
Since the voxel volume can now have different dimensions along X, Y and Z axes, specifying a single “range” no longer makes sense.
