Commits included: d0c58dab094953d29fc829721a0d94d3aa7fd869 (swap to macos-15-intel) and 616bfd577f13b1a047035a1b6290bf19c6c44de8 (include arch in artifact name).

October 2025 monthly summary for glotzerlab/hoomd-blue: Focus on energy calculation notation and documentation consistency across energy-related code and docs (external potentials and many-body terms). This work improved clarity, reduced ambiguity in energy expressions, and prepared the ground for future enhancements in usability and maintainability.

July 2025 (2025-07) focused on a targeted bug fix in the freud repository to correct UnitCell type inference with type hints, improving type safety and correctness. The change reduces potential runtime errors related to UnitCell typing and supports safer future refactors. A changelog entry was added to document the fix and improve release traceability, enhancing overall release hygiene and user confidence. This work demonstrates disciplined collaboration between debugging, typing, and release documentation, delivering concrete business value through increased reliability for downstream consumers relying on accurate UnitCell typing.

April 2025 (2025-04) — Freud development: delivered user-visible PMFT visualization improvements, API clarity enhancements, and maintainability improvements via refined type hints. Key outputs include PMFT plot enhancements with a new colormap option and fixes to attribute access and bounds, an API rename for Box: to_array renamed to to_box_params to improve clarity and consistency (with tests, changelog, and documentation updates), and cleanup of UnitCell API type hints for clearer signatures. All changes were accompanied by tests and changelog/docs updates to ensure backward compatibility and smoother adoption, reinforcing reliability, usability, and developer velocity across downstream users.

March 2025 monthly summary: Focused on delivering a feature to simplify data serialization and improve interoperability with GSD formats in freud. Key feature delivered: Box.to_array to export Box dimensions and tilt factors into a GSD-compatible flat array, with docstrings and tests to ensure correctness and usability. This reduces manual serialization effort and enables seamless storage of simulation data in GSD pipelines. No critical bugs were reported this month; ongoing improvements in test coverage and documentation. Technologies demonstrated include Python, unit testing, code documentation, and adherence to the GSD data format standards.

January 2025 monthly summary focusing on reliability, maintainability, and developer velocity. Delivered robust memory management enhancements in environment matching, extended Python exposure for character arrays, and strengthened documentation tooling—leading to clearer data flows, fewer regressions, and improved user experience for docs.

November 2024 highlights for glotzerlab/freud: Delivered a data export capability for HexaticTranslational, advanced BondOrder core functionality, and stabilized tooling and CI, driving reliability and user value. Alignments included submodule version updates and targeted code quality improvements, with documentation cleanups to improve developer experience.

October 2024 highlights across glotzerlab/freud: substantial progress in Python bindings, module exports, build tooling, and code quality. Key features include a SolidLiquid Python layer with full API exposure and exports, exports for QL/QLM and particle order, and ongoing enhancements to ContinuousCoordination and Cubatic integration. Build readability and maintainability were improved via colorized CMake output, linting/clang-format, and updated credits documentation. Several stability fixes were shipped, improving runtime reliability for SolidLiquid integration and Steinhardt calculations, along with a prepare-step fix.
