+  *) Retain source code compatibility for BN_prime_checks macro.

+  *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
+     DH_CHECK_P_NOT_SAFE_PRIME.
+     (Check if this is true? OpenPGP calls them "strong".)
+     [Ulf Möller]

   *) Merge the functionality of "dh" and "gendh" programs into a new program

      (instead of parameters) in future.
