While most of the projects that have signed up above are migrating to Python 3 only code bases, we are gathering information about the difficulties that can be encountered both by developers and users during this process.

We are thus collecting a list of things to be aware of for when transitioning that are less obvious. For example : as a developer, how to make sure that your package manager like pip does not upgrade your libraries to incompatible versions on Python 2. Check our repository for more information.
