. The changes are subtle. Most visible
is that the inside of the bun is hollow in the new version, which may also be
very slightly textured. But the new part no. is of course also a dead giveaway.
. New part no. is 77079. I have ordered
both colors from pick-a-brick (the old version is sold out), and the changes
are very subtle. The underside features are a bit more rounded with less texture
and the top tetrahedon seems to be a bit smaller. Part 30304 shows "(C) LEGO",
while 77079 shows "(C) 1999 LEGO Group".
In the attached photos, the new 77079 and the two right-most.
