  Changes between 0.9.4 and 0.9.5  [xx XXX 1999]
 
-  *) Apply Lutz Behnke's 56bit cipher patch. This should fix the problems with cipher
-     ordering and the new EXPORT1024 ciphers. Only two minor changes have been
-     made, the error reason codes have been altered and the @STRENGTH sorting
-     behaviour changed so eNULL ciphers are also sorted (if present).
+  *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
+     used (char *) instead of (void *) and had casts all over the place.
+     [Steve Henson]
+
+  *) Make BN_generate_prime() return NULL on error if ret!=NULL.
+     [Ulf Möller]
+
+  *) Retain source code compatibility for BN_prime_checks macro.
+     [Ulf Möller]
+
+  *) 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
+     "dhparam". The old programs are retained for now but will handle DH keys
+     (instead of parameters) in future.
+     [Steve Henson]
+
+  *) Make the ciphers, s_server and s_client programs check the return values
+     when a new cipher list is set.
+     [Steve Henson]
+
+  *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
+     ciphers. Before when the 56bit ciphers were enabled the sorting was
+     wrong.
+
+     The syntax for the cipher sorting has been extended to support sorting by
+     cipher-strength (using the strength_bits hard coded in the tables).
+     The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
+
+     Fix a bug in the cipher-command parser: when supplying a cipher command
+     string with an "undefined" symbol (neither command nor alphanumeric
+     [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
+     an error is flagged.
 
-     One other addition: the "ciphers" program didn't check the return code
-     of SSL_CTX_set_cipher_list().
-     [Lutz Behnke <behnke@trustcenter.de>, minor changes by Steve Henson]
+     Due to the strength-sorting extension, the code of the
+     ssl_create_cipher_list() function was completely rearranged. I hope that
+     the readability was also increased :-)
+     [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
 
   *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
      for the first serial number and places 2 in the serial number file. This
