IPython timeline

[mscuthbert]

Not part of the IPython/Jupyter team, but according to the timeline they should be on v. 7, but there's no movement on releasing a version 7 at present. Any objections to my extending v. 6 by a year and pushing other versions back? It's strange to make a unilateral move on someone else's project but I think it'd be helpful.

Yeah, we should update, thomas just released IPython 6.3 and master is python 3.4+ and will be 7.0 since this morning.

I'll update.
