Oct 1, 2025October 2025 (cctbx_project) focused on strengthening map/model workflows, improving CLI polish, and hardening cross-version Python compatibility. Key changes include DataManager enhancements to construct map_model_manager when only real_maps are available, refactored real_map/PHIL handling with independent guess_files application for model vs. real_map, and added tests to validate the new behavior. CLI quality was improved via CCTBXParser help formatting fix (dedenting extra spaces). Documentation and release process were updated to reflect 2025.9 changes and improvements to the variable resolution map calculation. Major bugs fixed centered on Python compatibility and pickle handling across versions. This included reverting the metaclass-based tracker due to compatibility issues with newer Python versions, reverting Python 2 pickle handling changes, and ensuring multiprocessing compatibility for newer Python releases (e.g., Python 3.14), addressing issue #1087. These fixes reduce runtime failures when running in mixed Python environments and improve interoperability across platforms. Overall impact: improved robustness and reliability of core map/model workflows, broader Python version support, and clearer, up-to-date documentation. These changes reduce maintenance risk, accelerate real-world data processing, and enable teams to run workflows across a broader set of environments. Technologies/skills demonstrated: Python (including multiprocessing considerations), iotbx/CCTBX data handling, PHIL configuration management, test-driven development, CLI tooling improvements, and documentation automation.

Aug 1, 2025August 2025 delivered a focused mix of user-facing feature improvements, build/CI reliability enhancements, and targeted UI cleanup for cross-platform robustness. Key feature work centers on the Release 2025.7 improvements, while packaging and CI work underpin sustainable releases across environments. A concise UI fix addresses a layout redundancy to prevent future regressions. Overall, the month increased data fidelity, reproducibility of builds, and developer productivity, setting the stage for faster, more predictable releases. Summary of impact: - Data export fidelity improved with mmCIF enhancements (auth_atom_id), a new variable resolution map calculation, and PHIL incompatibility reporting in CCTBParser, with CHANGELOG updated for 2025.7. - Build, packaging, and CI pipelines were hardened with a pyproject.toml-based setup (xfel), enhanced conda environment handling, Windows path fixes, CI/test infra improvements, and a new code formatting tool to boost reliability. - UI cleanup simplified the interface by removing an unnecessary alignment flag, reducing layout complexity and potential redundancies. - The combination of these changes yields higher data integrity, smoother cross-platform builds, and more streamlined development workflows, contributing to faster release cycles and improved downstream stability.
