Sep 1, 2025September 2025 (emdgroup/baybe): Delivered API hygiene, reliability improvements, and developer-focused enhancements across API, docs, tests, and release processes. Highlights include API cleanup with a renamed constructor from_values_mapped_to_unit_interval and shadowing fix; deterministic RNG enabling repeatable tests; metadata-driven organization and new metadata argument on convenience constructors; extensive documentation and example improvements; a formal release (0.14.0) with explicit Python in CI; and broad testing and cache improvements to boost stability and predictability. Major bugs addressed include ensuring OverflowError is raised where appropriate, ensuring type is always present in to_dict, disallowing type keys in misc metadata, and robust cache invalidation/clearing. Together these changes reduce risk, improve reproducibility, and accelerate adoption of the modern interface while preserving backward compatibility where feasible.

Feb 1, 2025February 2025 monthly summary for emdgroup/baybe. Focus was on delivering robust Pareto optimization features, cleaning up the API surface, and stabilizing multi-target workflows to accelerate data-driven decision-making for product and strategy teams. Key features delivered: - Pareto frontier enhancements: default reference point computed from data; supports flipping signs for custom reference points in MIN mode; interpolates the Pareto frontier along transformed points. - Code/API cleanup: removed unnecessary label arguments, eliminated square root usage in target computations, and dropped unused name attributes to simplify interfaces and reduce maintenance burden. - Benchmark and settings modernization: rename and restructure convergence/benchmark settings; extract convergence-related attributes into a subclass; move convergence benchmark functionality to a separate module; instantiate settings; enforce kw-only settings; docstring enforcement for the benchmark function. - Documentation and integration improvements: updated README to reference ParetoObjective; modernized cattrs integration; lockfile refreshed to reflect dependencies; docstrings refined for clarity. Major bugs fixed: - Fixed branch attribute handling for detached HEAD scenarios. - Strengthened error handling and compatibility: catch specific InfeasibilityError, improved multi-target compatibility validation, and clarified error messages. - Misc stability fixes: corrected variable references in examples and ensured unique target name validation. Overall impact and accomplishments: - Substantial API simplification and stabilization with a clear path toward multi-output and composite surrogate workflows. These changes reduce maintenance overhead, improve onboarding, and enable more reliable Pareto-based decision support across teams. Technologies/skills demonstrated: - Advanced Python design: kw-only settings, subclassing, docstring standards, and typing improvements. - Surrogate modeling and optimization: Pareto frontier, composite surrogates, and multi-target acquisition enhancements. - Dev tooling and docs: lockfile maintenance, thorough documentation updates, and testability improvements.
