Do you know why we stopped the car?

December 16 marks the two-year anniversary of the first public alpha release of Project OutFox; we would like to once again thank you for all the support and good vibes you have brought us as we work on this project. We have some big plans for OutFox in 2022, including new themes and touchscreen support, a new online system, and of course new modes and other modernizations!

5.3 Alpha 4.11 is our Second Anniversary Edition release; it is mainly focused on bug fixes and performance improvements, but we've also slipped in a few little previews of things we're working on for a future release (hint: try pressing F1 when you're in the editor).

There are a few important changes to note:

  • The names used for the executable and the directories for installation, save data, etc. have been changed from "StepMania"/StepMania 5.3" to "OutFox". This is part of the rebranding process that began on Alpha 4.9.8, and is needed to comply with the requirements for code signing and Microsoft SmartScreen verification. It also reduces the risk of conflicts with older versions of StepMania, so OutFox can be safely installed alongside StepMania 5.x without the risk of it overwriting or damaging profiles or stored scores..
    • Due to this change, you will need to move your profiles over to this new version. The old version will also need to be uninstalled manually; sorry about all of this, it is just for this update. On Windows, the uninstaller does not delete the Save folder, so you can specify your existing directory when installing Alpha 4.11.0 if you prefer.
  • The beat and popn game types have been renamed to be-mu and po-mu; this change does not affect the ability to load chart files with the old names, but you will have to rename the folders accordingly if you have noteskins for those game types.


This is just a recap of the major, user-facing features and technical changes. You can read the full changelog on the Alpha 4.11.0 page on
