Changelog
Daniel (12 February 2007)
+- Rob Crittenden added support for NSS (Network Security Service) for the
+ SSL/TLS layer. http://www.mozilla.org/projects/security/pki/nss/
+
+ This is the fourth supported library for TLS/SSL that libcurl supports!
+
- Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent
to the debug callback.
