  Changes between 0.9.1c and 0.9.2
 
+  *) Major rework of DES function declarations, in the pursuit of correctness
+     and purity. As a result, many evil casts evaporated, and some weirdness,
+     too. You may find this causes warnings in your code. Zapping your evil
+     casts will probably fix them. Mostly.
+     [Ben Laurie]
+
   *) Fix for a typo in asn1.h. Bug fix to object creation script
      obj_dat.pl. It considered a zero in an object definition to mean
      "end of object": none of the objects in objects.h have any zeros
