Nov 2025: Delivered Beluga 2.1.0 with Bazel build support, ROS 2 compatibility, likelihood sensor model enhancements, and documentation updates. Release committed as c0b2740cebb60aaa9912973a16bd9597689d4914 (#538), marking a substantial improvement in build reliability, ecosystem interoperability, and usability.

In Sep 2025, focused on streamlining the beluga project by dropping outdated ROS Noetic support, updating docs and build configurations, and aligning the pipeline with newer ROS releases. This reduces maintenance burden and sets the stage for future ROS migrations. No major bug fixes this month; improvements centered on deprecation, documentation, and build system alignment. Overall impact: cleaner surface area, faster onboarding for supported distros, and clearer direction for future releases.

June 2025: Delivered a critical fix in ros2/rviz to correct 3D mesh orientation during model import, aligning with ROS Y-Up convention and ensuring accurate visualization for glTF, glb, and VRM assets. This prevents misalignment in RViz and improves user confidence in asset previews.

March 2025: Delivered major CI improvements for Ekumen-OS beluga, introducing static analysis and code coverage enforcement in the weekly pipeline, and configured scheduled Codecov reporting for the humble ROS distribution. The changes enhance early quality validation, reduce regression risk, and provide clearer quality signals for weekly builds. No major bugs fixed this month; maintenance-focused changes strengthened CI reliability and release readiness across the beluga repo. Skills demonstrated include CI/CD automation, static analysis integration, code coverage tooling, and ROS ecosystem awareness.

December 2024 monthly summary for Ekumen-OS/beluga focusing on CI/CD stewardship and repository hygiene. Key features delivered include removing deprecated ROS 2 Iron Irwini support from CI pipelines and documentation, and implementing fork-aware CI gating to prevent weekly and docker CI runs on forks. Major bugs fixed include eliminating stale ROS 2 Iron CI images and configurations that could trigger failures, and correcting CI scheduling so fork runs are avoided. Overall impact includes reduced CI failures, lower maintenance burden, and compute resource savings, enabling faster feedback and more reliable releases. Technologies demonstrated include GitHub Actions workflow configuration, Docker image housekeeping, and documentation cleanup. Business value: improved reliability, cost efficiency, and smoother contributor experience.

October 2024: Focused on expanding library extensibility and improving contributor onboarding for Beluga. Delivered a comprehensive Beluga Extension Guide that details how to extend the library across motion models, sensor models, and estimation algorithms. The guide includes prerequisites, implementation considerations, and example code to accelerate community contributions. This work was supported by the dedicated commit adding the guide (08e682fe0795952ad01fc991979fe3056a27c29a).
