Changes between 0.9.6d and 0.9.7 [XX xxx 2002]
+ *) Fix escaping of non-ASCII characters when using the -subj option
+ of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
+ [Lutz Jaenicke]
+
*) Make object definitions compliant to LDAP (RFC2256): SN is the short
form for "surname", serialNumber has no short form.
Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
