Project and montage compatibility WL12 and WL13

Hi!

Is there any backwards compatibility between WL12 and WL13 regarding projects and montages?

Like always:
WaveLab version X+1 loads WaveLab version 0…X montages.
That is, WaveLab 13 loads WaveLab 6/7/8/9/10/11/12 montages.
But not the other way round.
