Add description of relativistic integrals

release.notes.4.0

@@ -20,6 +20,9 @@ Additional major additions to the capabilities include:
   o The Douglas-Kroll(-Hess) approach is implemented. It can be used at all levels 
     of theory. Gradients have been implementing allowing for Douglas-Kroll including 
     geometry optimizations and frequencies
+  o Inclusion of code to evaluate relativistic integrals based on Dyall's modified Dirac
+    (DmD) equation. This provides a one-electron approximation very similar to the
+    Douglas-Kroll-Hess approach. Gradients are also available for this method.
 
 Again, for each of these capabilities, the user is referred to the User Manual for
 more information.
