Hello everyone,
Building upon the refactored version of RouteFlow we released 2 months ago,
we have a new version with several improvements. The most important change
in this new version is the new configuration system. It's now possible to
associate datapath ports to VM ports in a predefined way, making RouteFlow
much more reliable and easier to configure. This was a long-standing issue
that affected lots of users, and we hope this will make RouteFlow easier
for everyone.
