Oct 1, 2025Concise monthly summary for 4C (October 2025): Delivered a major Documentation System Refactor and Relative Link Enhancement for the 4C repository. Streamlined the documentation generation pipeline by removing redundant/outdated generation functions and updating build/scripts to support new doc structures and content. Implemented relative links across internal documentation to improve robustness when hosting base URLs change.

Aug 1, 2025In Aug 2025, delivered a Poisson tutorial with solver usage demonstrations for scalar transport and thermal problems and enhanced documentation to improve physics explanations and cross-tutorial navigation. This work strengthens onboarding, accelerates self-service learning, and showcases 4C's Poisson capabilities. Implementation was carried out through three focused commits to add tutorial content and clarifying notes, enabling reproducibility and easier maintenance: 2f916e8e94a621194e53eff7cb5612ed357ba191 (Add a tutorial on the poisson problem), 6c026a283115bf76f43f298861ea52beb854cd6b (Add a few words on the physics behind the tutorial), and 8bb3fd567a04583cdd3d497fc6d30d839c228675 (Introductory words on the order of the tutorials).

Oct 1, 2024October 2024: Implemented repo hygiene improvement by excluding the .devcontainer configuration from Git tracking (commit 457ecc2767f32b5ebf0040f20305c767079ef4d9). This prevents local dev environment files from entering version history, reduces noise in commits, and simplifies onboarding for new contributors. No major bugs fixed this month; maintenance and quality improvements were prioritized.
