ws 6 seems to drop support for Node 4 and 5 - https://travis-ci.org/cettia/cettia-javascript-client/builds/526732614

And ws 7 drops support for Node 6 - websockets/ws@1e6999b

We need to decide whether to support Node 4 and 5.

[flowersinthesand]

We've decided not to break the current support policy (Node 4+) in v1.
