If you mean the direct opening of PZ3 files, yes, I think 4 is the first. You can still do the old-fashioned OBJ export to 3.1, of course.

Just a note: the free 3.1 is limited to 1024 x 768 renders, but is otherwise complete as far as I know. Hoping to pick up a copy this weekend.

Oops, cross-post! :}
