Greetings, There are some patches that add support for building wheels. The patch adds a `[wheel]` section with `universal = True` `universal=True` means the applications supports py2/py3 which is not the case for most (all?) openstack projects. So, please, do not approve those patches. Glance case: https://review.openstack.org/#/c/57132/ Cheers, FF -- @flaper87 Flavio Percoco
