OpenStack community decided to officially support Python 3.5 by the end of Pike cycle: https://governance.openstack.org/tc/goals/pike/python35.html To track this work in TripleO, I created a blueprint: https://blueprints.launchpad.net/tripleo/+spec/support-python-35 I'm also tracking the work completion in the governance repository: https://review.openstack.org/#/c/424857/ I'll start the evaluation of work that needs to be done and document it in the previous link. Anyone volunteer to help on $topic is very welcome, ping me on IRC or here by e-mail. Thanks, -- Emilien Macchi
