* @brief The implementation of the diaspora protocol
*
* The new protocol is described here: http://diaspora.github.io/diaspora_federation/index.html
- * Currently this implementation here interprets the old and the new protocol and sends the old one.
- * This will change in the future.
+ * This implementation here interprets the old and the new protocol and sends the new one.
+ * In the future we will remove most stuff from "valid_posting" and interpret only the new protocol.
