Subject Re: IPv6 Feature branch
Date Mon, 24 Aug 2015 21:10:07 GMT
Dhruba's off in a different timezone. So he might not be able to. I'll ask

Nate, I, and Nemanja will be working on this. We're really hoping the patch
will be living for just a few weeks or a month at most.
Hopefully a good deal of the code we write will be testable so that will
result in some good clean up. Though it won't be a primary top line goal.
