Warning

This is the documentation the latest work-in-progress version of MPF!

This is the documentation for MPF 0.57, which is the “dev” (next) release of MPF that is a work-in-progress. This is probably ok, and means you’ll be on the latest, cutting-edge version of MPF.

However, if you want a more stable version, select the v:stable version from the lower-left corner of this page. You can always update to the latest at any time.
