January 2026: Delivered CGAL-related updates across two major repositories to improve geometry reliability and downstream packaging. Upgraded CGAL to 6.1.1 in microsoft/vcpkg with geometry algorithm bug fixes (commit 59acf86ded50f1f10fbbb47e65b0f15f94b5cdfa). In conan-io/conan-center-index, added CGAL 6.0.3 and 6.1.1 to the Conan package set (commit e883e505794bfa91e1d4d9033672d743a1fe8ee8). These changes improve build reproducibility, compatibility for downstream users, and reduce integration friction.

November 2025: Delivered CGAL 6.1 integration across two packaging ecosystems (microsoft/vcpkg and conan-io/conan-center-index). Implemented the library update with versioning adjustments, new source URL inclusion, and baseline configuration alignment to CGAL 6.1, ensuring compatibility and reproducible builds. This cross-repo alignment reduces upgrade friction for downstream users, improves dependency accuracy, and strengthens maintainability of CGAL-related packaging in both workflows.

October 2025 monthly summary for conan-center-index (conan-io/conan-center-index). Focused on improving contributor experience by restructuring local recipe development docs to clarify linting guidance and improve navigation. Specifically, consolidated linting-related entries under a single 'Testing' heading and removed redundant sub-bullets in developing_recipes_locally.md, resulting in clearer guidance for local recipe development. The work leveraged a targeted docs update with a commit that updates the table of contents in developing_recipes_locally.md (commit 52bf6367b0ad9f247c72f1918115e02f6a9bd054), building on prior work referenced in #25875 and tracked under #28420. Business value includes faster onboarding for new contributors, reduced ambiguity in local development, and a more maintainable documentation surface aligned with the repository's linting/testing workflow.

September 2025: Delivered CGAL library version updates in Conan Center Index to keep releases current, reproducible, and user-ready. Added versions 5.6.3 and 6.0.2 with validated SHA256 checksums and download URLs. Maintained traceability with a dedicated commit. No major bug fixes identified this month.

Month: 2024-10 — Focused CGAL memory safety improvements in the microsoft/vcpkg port. Delivered an upgrade to CGAL 6.0.1, removed a legacy patch, and updated the SHA-512 checksum. These changes improve memory deallocation correctness and robustness across CGAL modules, reducing risk for downstream users and stabilizing builds.
