  Changes between 0.9.6 and 0.9.7  [xx XXX 2000]
 
+  *) New function X509_signature_print() to remove duplication in some
+     print routines.
+     [Steve Henson]
+
   *) Add a special meaning when SET OF and SEQUENCE OF flags are both
      set (this was treated exactly the same as SET OF previously). This
      is used to reorder the STACK representing the structure to match the
