Can use recent versions of requirements?

[okkhoy]

Versions of the modules required are pinned in the requirements. If there is no specific need for these versions, we can simply mention the module name and let python decide the version.

In my case, some packages were downgraded: see install log below

    DEPRECATION: Uninstalling a distutils installed project (certifi) has been deprecated and will be removed in a future version. This
     is due to the fact that uninstalling a distutils project will only partially uninstall the project.

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I'm using virtualenvs, so this is not an issue. These dependencies are what is required by PyGithub and requests.

[okkhoy]

I use virtualenv too; was just checking if it was possible to use the latest versions. Nevermind, will close the issue.

I think it's safe to freeze the version. We can't always rely on the backward compatibility of the future versions.
