We have released StepMania 5.3 Alpha 4.5.8. This is an interim update that features some bug fixes and improvements over 4.5.6 as we prepare for our next major build, Alpha 5.0.
For download links and a complete changelog (including details on technical changes also present in this build), visit the release page. Builds are currently available for Windows, Linux, and macOS (no Discord support). On Linux, a "legacy" amd64 is avaliable, built on older glibc and also excluding Discord support.
We are migrating to GitHub for public issue tracking going forward.
