Mar 1, 2026March 2026 (dealii/dealii): Implemented a Build System Enhancement to copy compile features across targets, increasing build consistency and CI reliability. The change propagates TARGET_COMPILE_FEATURES via the copy_target_properties() macro, ensuring compile features are retrieved and appended across targets to prevent configuration drift. Delivered with a focused CMake-based build-system improvement that aligns with modular target design and repeatable builds.

Feb 1, 2026February 2026 (dealii/dealii): Focused on licensing governance and repository hygiene to improve compliance, maintenance, and long-term stability. Delivered license header and copyright-year alignment across the codebase—10 commits updating headers in source, include, tests, doc, cmake, contrib, and utilities including generate_lapack_templates—ensuring consistent terms and easier future audits. Followed by project cleanup removing obsolete TestBoostBug files from cmake/configure to reduce maintenance overhead. These changes reduce drift between documentation, build configurations, and code, and strengthen audit-readiness for licensing terms. Technologies demonstrated include Git-based collaboration, cross-repo license maintenance, build-system hygiene with CMake, and documentation consistency, delivering tangible business value through risk reduction and improved maintainability.
