The Havana release of OpenStack, came out in October 2013, contains several significant changes and new features in the networking component. OpenStack Networking has changed name from 'quantum' to 'neutron'. It lays the foundation for supporting heterogeneous network components with the introduction of the ML2 (modular layer 2) plugin. The first implementations of FireWall as a Service (FWaaS) and VPN as a Service (VPNaaS) are now included. These features were demonstrated by Cisco developers at the OpenStack meetup in Boston in Oct 2013.
