To be precise, Node.js 6.x will include V8 5.0. There has been a little discussion on being able to include V8 5.1 down the road, maybe, but there is nothing concrete on it at this point.

Also, the fate for tail-call-elimination is pretty uncertain at the moment; see: https://github.com/tc39/proposal-ptc-syntax

Oh hi, fancy seeing you here :]

Note that ptc syntax _ensures_ tail calls, tail calls themselves have _already_ been approved in ES2015 and are live in V8 (under a flag), you can follow their status here: https://bugs.chromium.org/p/v8/issues/detail?id=4698
