Implemented test configuration changes and dependency constraints to improve determinism, repeatability, and maintainability of the test suite.

May 2025 monthly summary for glass-dev/glass: Delivered robustness improvements, feature enrichments, and API modernization with clear business value. Implemented a robust get_namespace bug fix to skip None values, reducing NoneType-related errors in namespace validation and improving data integrity. Refined clustering analytics in the Galaxy Redshift example by switching to position_weights() for weights, yielding a more accurate effective galaxy count and better redshift distribution analysis. Migrated to cosmology.api and updated dependencies to align with modern cosmology API standards, including array-api-strict 2024.12, improving compatibility, maintainability, and test stability for future releases. These changes reduce runtime risks, enhance analytics accuracy, and position the project for smoother releases and easier onboarding of new contributors.

April 2025 (Month: 2025-04) — Glass core delivered two key features with strong emphasis on correctness, reliability, and API clarity. The RadialWindow component was refactored to a dataclass with immutability and automatic zeff computation when not provided, accompanied by tests to verify immutability and automatic calculation. In parallel, the Glass library naming was cleaned (xp -> xq, p -> q) to improve algorithm readability for NNLS and ND interpolation. These changes reduce maintenance risk, improve developer productivity, and lay a solid foundation for future feature work. No critical bug fixes were required this month; the focus was on refactors, test coverage, and API clarity to enable faster, safer business value delivery.

March 2025 highlights for glass-dev/glass focused on documentation hygiene, reproducibility, workflow reliability, and code quality. Key features delivered include consolidating contributor documentation and modernizing contributor tooling; adding a reproducible RNG in the legacy notebook; standardizing changelog workflow in PR templates; enhancing pre-commit checks for large files with controlled exceptions; addressing a plotting default-argument bug; and refactoring weight calculations into classes for better organization and testability. These changes improve onboarding, CI stability, experiment reproducibility, and maintainability, while preserving performance.
