Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) New function X509V3_add1_i2d(). This automatically encodes and
+ adds an extension. Its behaviour can be customised with various
+ flags to append, replace or delete. Various wrappers added for
+ certifcates and CRLs.
+ [Steve Henson]
+
*) Fix to avoid calling the underlying ASN1 print routine when
an extension cannot be parsed. Correct a typo in the
OCSP_SERVICELOC extension. Tidy up print OCSP format.
