Ioflo is now at version 1.0. The framework features have been pretty stable for some time at 0.9.X so we decided now was a good a time as any to go to 1.0.
Also coincident with the version is a change in the license. We decided to switch from MIT to Apache 2.0. The motivation for the switch is that big applications of Ioflo are RAET and SaltStack and they both use the Apache2.0 license. This provides a consistent licensing. Also Apache2.0 has specific provisions for user contributions that clarify intent as well as CLAs.
