Nov 1, 2025November 2025: Delivered architecture and physics enhancements for double compact object evolution in POSYDON. Refactored step_dco to inherit from step_detached, enabling a cleaner, more modular evolution pipeline and consistent parameter usage. Updated natal kick handling and gravitational radiation calculation documentation to improve physical accuracy, with conversions to floats to prevent runtime failures. Performed extensive code cleanup and standardized parameter usage across the repository, reducing technical debt and easing future development. CI/test alignment completed with pre-commit fixes and config updates; PR #725 consolidates changes (commit 7ccd66d8077edd51872353ff2cc2d9a132b883d1).

Sep 1, 2025September 2025 (POSYDON): Delivered a robust, modular detached evolution framework with improved state handling and controllable physics for magnetic braking and gravitational radiation, alongside import stability and maintenance fixes to ensure robust binary evolution modeling. Strengthened data handling and initialization routines to improve reproducibility and accuracy across metallicity and remnant evolution. Enhanced population saving, binary failure handling, and support for user-supplied single-star grids (inlists). Standardized star-state naming and resolved unit-test imports, and completed comprehensive documentation and versioning updates to ease onboarding and future changes. Overall, a more stable, scalable, and engineer-friendly platform for binary evolution research with clearer capability boundaries and improved data integrity.

Aug 1, 2025Month: 2025-08 — POSYDON repository: POSYDON-code/POSYDON. Focused on security, reliability, and performance. Implemented Warning Display Enhancement to exclude source code text from warnings, introducing nosrc_code_format and updating unit tests. Released POSYDON 2.0.2 with API evolution and physics fixes: added optimize_ram to BinaryPopulation.evolve, refactored distance handling, replaced None with np.nan for float conversions, and corrected magnetic braking dOmega updates. Strengthened test coverage to guard against regressions. Impact: more secure, robust, and scalable simulations with improved memory usage and physics fidelity.
