  Changes between 0.9.8 and 0.9.8a  [05 Jul 2005]]
 
+  *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+     (part of SSL_OP_ALL).  This option used to disable the
+     countermeasure against man-in-the-middle protocol-version
+     rollback in the SSL 2.0 server implementation, which is a bad
+     idea.
+
+     [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+     for Information Security, National Institute of Advanced Industrial
+     Science and Technology [AIST], Japan)]
+
   *) Add libcrypto.pc and libssl.pc for those who feel they need them.

   *) Minimal support for X9.31 signatures and PSS padding modes. This is
      mainly for FIPS compliance and not fully integrated at this stage.

  Changes between 0.9.7f and 0.9.7g  [11 Apr 2005]
 
+  [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
+  OpenSSL 0.9.8.]
+
   *) Fixes for newer kerberos headers. NB: the casts are needed because
      the 'length' field is signed on one version and unsigned on another
      with no (?) obvious way to tell the difference, without these VC++
