 Changes between 1.0.2 and 1.1.0  [xx XXX xxxx]

+  *) Experimental support for a new, fast, unbiased prime candidate generator,
+     bn_probable_prime_dh_coprime(). Not currently used by any prime generator.
+     [Felix Laurie von Massenbach <felix@erbridge.co.uk>]
+
  *) New output format NSS in the sess_id command line tool. This allows
     exporting the session id and the master key in NSS keylog format.
