The StepMania project is proud to announce the release of ; this is the first publicly-released beta build based on the "5_1-new" branch (see for details), so it is significantly different from the previous alpha builds named "5.1" that were released in 2016.
StepMania 5.1 focuses primarily on internal enhancements, especially for content creators (including but not limited to controller support improvements, support for custom songs in profiles on USB drives, fullscreen improvements on X11, a large number of new modifier effects, and a new image caching system), while preserving compatibility with StepMania 5.0.x content such as themes and noteskins. Speaking of themes, by far the most significant, user-visible change on 5.1 is a new default theme known as Lambda, which features a brighter appearance and a cleaner interface.
Source code, a Windows installer, and a macOS binary build are available now. If you encounter any issues with this release, please do not hesitate to report them on our . Please note that StepMania 5.1 uses a separate folder for user files and profile data than StepMania 5.0, so you may have to migrate content to the new location, or configure separate from your user data directory.
