March 2026: Delivered MAVLink version bump to 2026.3.3-1 across ROS distributions in ros/rosdistro. Updated humble, jazzy, kilted, and rolling distribution.yaml and related packaging to include latest MAVLink features and fixes. This work aligns packaging across distributions, reducing drift and improving build stability. No major bug fixes were required this month; primary business value comes from keeping ROS 2 releases current and packaging-consistent, enabling downstream projects to rely on up-to-date MAVLink capabilities. Technologies demonstrated include YAML-based distribution management, Bloom packaging workflow, and cross-distro config maintenance, with visible impact on downstream CI and release readiness.
