Hello Doug,

thanks for your explanation. I was a little bit confused by changes to 
stable branches with python3-first topic as I thought it has to do 
something with adding new test configuration for python3.

But as you explained this is about moving zuul-related configuration, 
which is a part of python3-first goal (but it is not related to 
supporting python3 by projects IMHO :) )

Anyway, it is now clear to me and sorry for making this confusion.


Best,

Dariusz Krol
