The OPNFV community's 4th release, Danube, came out roughly 2 weeks ago. This release integrates the MANO layer (OPEN-O, OpenBaton, OpenStack tacker), so now there is an open source reference architecture for the entire NFV stack minus VNFs. Or in other words OPNFV integrates MANO + VIM + SDN Controller + NFVI software with continuous testing. Pretty cool, huh? Additionally there are numerous enhancements around data plane acceleration, architecture improvements, feature enhancements and hardening. See the official OPNFV blog.
