Heroku build failing.

[hammygoonan]

There seems to be an issue with the Heroku build which I thought you might like to know about. The 'magic' button isn't working. Here' the log from Heroku:

-----> Python app detected

 !     The latest version of Python 3.6 is python-3.6.6 (you are using python-3.6.4, which is unsupported).

 !     We recommend upgrading by specifying the latest version (python-3.6.6).

       Learn More: https://devcenter.heroku.com/articles/python-runtimes

-----> Installing python-3.6.4

-----> Installing pip

-----> Installing SQLite3
