They are the same and yet different.  0.4.3 is "new scipy".  You will
find more on the list if you look for information about new scipy. 
You will probably get a more detailed answer from some one else later,
but the biggest difference is that "old scipy" - i.e. <=0.3.2 depends
on Numeric and/or numarray for matrices and arrays.  Travis Oliphant
has redesigned the matrix/array API for "new scipy".  You can read
about why he did this in the first chapter of a book he has written
about new scipy.  The first two chapters can be downloaded for free
with a link on this page:

I don't have a good feel for how stable new scipy is and how many
people are using it for their everyday work.  I am actually using old
scipy still myself.
