Version 3.0.0 - 13 of July 2012 (unreleased experimental version)
* Major version change due to incompatible CLI interface with version 1.x.x and 2.x.x
* Major version change due to a change of API behaviour with the forked worker processes
* Change : Many printed message have changed, including OPEN MultiProtocol
* CLI Change: use new ini file and environment values for configuration
* API Change: send "up" message to worker process when neighbour OPEN negotiation is complete (not on TCP up)

* API Change: use the word withdrawn when the route was received, withdraw when it is an action, same for announce and announced

* API Addition: requires peer-updates under 'process' to announce peer status changes
* API Addition: show routes, show routes extensive, show neighbors
