May 1, 2025May 2025 — iiasa/message-ix-models: Stability-focused month delivering essential data-quality improvements to the Materials Reporter. Implemented a fix to replace infinite values with zero, preventing INF-driven failures in material reporting and downstream analytics. While no new features were released this month, the bug fix significantly enhances data integrity, reliability of dashboards, and trust in reporting pipelines. The change is lightweight, low-risk, and ready for validation in the next release cycle.
