I keep meaning to read up on what's planned for zuul v3, the recorded talk
from the last summit was good in explaining some of the benefits for users
of the new capabilities, but I'd also love to get up to speed on how some
of the backend changes will improve things for operation. Is there some
blog posts or something that goes into this?

Will any of that break those still using zuul/nodepool with Jenkins? Or is
that orthogonal? I still don't have a full handle on how
Jenkins/Zuul/Nodepool interacts besides that it uses gearman.

Looking forward to checking it out, and hopefully getting involved around
zuulv3 integration with GitHub!
