  Changes between 0.9.6 and 0.9.7  [xx XXX 2000]
 
+  *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
+     value of OPENSSLDIR.  This is available via the new '-d' option
+     to 'openssl version', and is also included in 'openssl version -a'.
+     [Bodo Moeller]
+
   *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
      call failed, free the DSA structure.
