This is the dev documentation for an unreleased version of MPF!
This is the documentation for MPF 0.55+, which is the “dev” (next) release of MPF that is a work-in-progress. Unless you’re specifically looking for this version, you probably want to use the version of documentation called “latest” which is for the latest released version of MPF. That documentation is at docs.missionpinball.org/en/latest.
Since MPF is a work-in-progress, we’re making a lot of changes and progress with dozens of code updates per week.
The links here explain how MPF version numbering works, what features are in what versions, and a roadmap of ideas and plans for the future.
The latest released version of MPF is 0.54.x, but the documentation you’re reading now is valid for MPF versions 0.55+.
