Yes, I believe that they do.  I think the important phrase is:
exact versions of these libraries listed as minimal versions

which isn't very clear, but saying use the minimal version listed on
the page...  They probably had someone try w/ 4.3.3 and wonder why it
wasn't working so they added the exact verbage...
