I've just built python-pip-18.0-1.fc29.
It has a lot of breaking changes, so please file bugs if you have
problems. We do not plan to upgrade pip in stable Fedora releases.
Release notes: https://pip.pypa.io/en/stable/news/
See notes for 18 and 10, as we skipped 10.
Note that upstream changed version scheme, nothing existed between 10
