+WHAT'S NEW
+
+In version 1.0.1:
+-  The MLD_SIZEOF() function has been redefined to be INTEGER(8), so
+   as to be able to measure large data sets.
+-  The internals of the multilevel preconditioner have been repackaged
+   in a more structured fashion; no changes are needed in the user
+   code.
+-  Note that we now need version 2.3.1 of PSBLAS.
