Django 2.0 was released this month: https://docs.djangoproject.com/en/2.0/releases/2.0/ It's the first version of Django that only supports Python 3, so we'll need to switch to Python 3 first (bug 1330474). Whilst there will be no new versions of Django that support Python 2.7, the Django 1.11 release we're using is an LTS release, so we have time to get switched over to Python 3.

Commit pushed to master at https://github.com/mozilla/treeherder https://github.com/mozilla/treeherder/commit/8f8671c8dcd3a5c36c6d1e2a02c2a88d8f6501ba Bug 1426683 - Add pyup ignore markers for Django v2 (#3061) To keep pyup quiet for now, and ensure it still opens PRs for 1.11.x updates in the meantime. The Django 2.0 update will have to wait until we're using Python 3.
