August 2025: Focused on strengthening code quality tooling and maintainability for the nautobot/cookiecutter-nautobot-app template. Key work centered on upgrading the pymarkdownlint dependency to 0.9.30 across configurations to enable selective rule enablement and ensure compatibility with newer Python versions. The lint configuration was simplified by removing broad disabled-rule blocks and enabling specific rules such as blanks-around-lists and list-anchored-indent. No major bug fixes were required this month; stability was preserved while enabling longer-term improvements. These changes reduce configuration drift, accelerate CI feedback, and set the stage for simpler rule tuning in future iterations.
