Not quite: if you're using version x.y.z then it may have an
additional function, etc. that was added compared to just x.y ; as
such the bounds are >= x.y.z && < x.(y+1)

That said, very few packages seem to have versions where they add
something without removing or modifying something else, so in most
cases you are correct.
