May 1, 2025May 2025 Monthly Summary for GIScience/openrouteservice: Focused on stability and correctness in hazmat profile handling by addressing a critical bug in dynamic weight computation. Delivered a fix so hazmat: false is not treated as a defined profile parameter, preventing requiresDynamicPreprocessedWeights from wrongly returning true. Reworked the validation to use hasAttributes against default initializations. Included test adjustments and a changelog entry to document the fix. Overall, improved safety-critical routing reliability and reduced risk of incorrect weight calculations without introducing new user-facing features.
