Python 3.7 Support and newer Ruamel

MPF 0.52 supports Python 3.7 which will hit mainstream soon. It improves performance in some areas. Additionally, we updated to a newer version of our YAML parsing library which should yield some startup performance improvements.


Some areas received polishing:

New Hardware Support

A few new hardware platforms are supported in 0.52:

Upgrade instructions

To upgrade, use pip:

pip install --upgrade mpf mpf-mc

Note: if you installed mpf with pip3 or kivy -m pip3, you’ll need to use the same pip command as you did then.

If you use MPF Monitor, that will need an upgrade too

pip install --upgrade mpf-monitor


We extended the documentation. The config reference for almost all devices has been completed. We added a section about game design and how to lay out your modes. We documented common modes based on questions in our forum. Please ask there if you are missing anything.
