Sep 1, 2025September 2025 OpenFreeEnergy/openfe monthly summary: In September, the team delivered a major CLI mapping overhaul with KartografAtomMapper set as the default, updated defaults for distance, hydrogen mapping, and ring matching to enhance RBFE network planning. We hardened constraint atom mapping error handling with a Counter-based check to prevent multiple deletions and improved exception messages, complemented by tests and release notes updates. These changes improve reliability, debugging efficiency, and user-facing feedback, driving better planning accuracy and faster iteration.
