Changes between 0.9.8f and 0.9.8g [xx XXX xxxx]
- *)
+ *) Implement certificate status request TLS extension defined in RFC3546.
+ A client can set the appropriate parameters and receive the encoded
+ OCSP response via a callback. A server can query the supplied parameters
+ and set the encoded OCSP response in the callback. Add simplified examples
+ to s_client and s_server.
