You can use Python 3.6.0 in CircleCI (in the default Ubuntu 14.04 image) right now by having the following in circle.yml
:
machine:
pre:
- cd /opt/circleci/.pyenv; git pull
python:
version: 3.6.0
What you are giving up here is about 2 minutes of build time though. This is a workaround only if you NEED 3.6.0, until the new CCI Ubuntu 14.04 image comes out within the next couple weeks or so.
