July 2025 (2025-07) — MaCh3 (mach3-software/MaCh3) focused on improving CLI usability and maintainability rather than adding new features. Key accomplishment: ProcessMCMC Usage Guidance Enhancement, clarifying the CLI error message to detail expected arguments across single, two-, and three-chain runs. This reduces user confusion, accelerates onboarding, and lowers support overhead by aligning runtime guidance with documented usage. No major bugs fixed this month; the emphasis was on quality of life improvements and code clarity. The change is tracked via a focused commit, enabling traceability and safer future iterations.
