[Numpy-discussion] Circle CI moving from 1.0 to 2.0

[Matti Picus]

I stumbled across this notice (only seems to appear in a failed build)

"This project is currently running on CircleCI 1.0 which will no longer 
be supported after August 31, 2018. Please start migrating this project 
to CircleCI 2.0 <https://circleci.com/docs/2.0/migration/>."

Here is the original link https://circleci.com/gh/numpy/numpy/2080

Is this an artifact that can be ignored or do we need to migrate, if so 
has anyone already done it for their project?
