Supporting multiple versions of Python is something we’ve done for a while now
on Pinax apps, however, we’ve mostly relied on Travis CI to execute tests in
each version. This is inefficient and leads to a lot of follow up commits to
fix as well as wasted time as we wait on builds to finish.
From the earliest days of Pinax, it has been our goal to make it easier and
faster to launch new web applications. Before Django adopted the project template,
Pinax had a collection of project templates we called starter projects.
