Oct 1, 2025

October 2025: Two high-impact deliverables across autoware.universe and autoware_launch focused on maintainability and simulation readiness. Key outcomes include standardizing code formatting (isort aligned with Black and 100-char line length) and enabling CARLA sensor kit support with diagnostics, pointcloud preprocessing, updated obstacle-avoidance velocity parameters, and dependency fixes.

May 1, 2025

May 2025 monthly summary for autoware. Focused on standardizing development tooling and enabling build-from-source across the Autoware project. Key delivery: standardization of package naming from plotjuggler-ros to plotjuggler across Ansible config and repository definitions; added plotjuggler_ros repo to tooling to support builds from source. Major bug fix: aligned tooling references and repository names (commit 0e3c9f983ce3f1abb42ea7e97efaf7e0a0ae5478) to rename plotjuggler-ros to plotjuggler, eliminating naming drift. Impact: improved build reliability, reduced onboarding time, and simplified maintenance across Autoware repositories. Technologies demonstrated: Ansible configuration, repository management, build tooling integration, and ROS tooling alignment.

March 2025 monthly highlights focused on stable delivery and maintenance improvements across two repositories.

February 2025

1 Commits

Feb 1, 2025

February 2025 (Month: 2025-02) focused on stabilization of tier4/autoware_launch. No new features were delivered this month; instead, a critical rollback was performed to revert the V2I traffic light integration, removing V2I parameters from the traffic light configuration and effectively disabling V2I functionality. This rollback ensures production safety and deterministic behavior while enabling planning for future V2I work. The change is documented and ready for validation in upcoming cycles.

January 2025

7 Commits • 4 Features

Jan 1, 2025

January 2025 summary: Delivered automated release and governance tooling across multiple repositories (autoware.universe, autoware.core, tier4/autoware_launch), improved packaging consistency, and enhanced system observability. A critical versioning issue in autoware_string_stamped_overlay_rviz_plugin was fixed to ensure correct dependency tracking. These efforts reduce release toil, improve governance, and strengthen observability, enabling faster, more reliable releases and clearer ownership. Technologies demonstrated include GitHub Actions CI/CD, multi-package version management, automated changelog generation, and network observability enhancements.

December 2024

3 Commits • 1 Features

Dec 1, 2024

December 2024 monthly summary: Delivered major feature integration, targeted bug fixes, and dependency stabilization to establish a stable Autoware baseline across three core repositories. Achieved alignment around the 0.40.0 baseline with cross-repo coordination and improved release readiness.
