Release Notes

Release Date: February 7, 2016

Overview

The v1.2 Floodlight release builds upon the improvements made in v1.1, with emphasis on more robust and feature-rich core modules, including completely rewritten Device, Topology, and Forwarding modules. A new Statistics module provides port bandwidth statistics and also serves a multithreading and statistics collection example. IPv6, Link latency, OF-DPA, message listener, and many more exciting features are discussed below. Many thanks to everyone who has contributed to and supported Floodlight!
