May 2025 monthly highlights: Delivered critical maintenance and deprecation updates for the ROS Noetic distribution, consolidating packaging work across core packages (geometry2, ros_comm, rqt_nav_view, actionlib, nodelet_core, dynamic_reconfigure). Removed deprecated components (slic) and applied stability-driven reverts (voice_text), while updating distribution metadata to reflect end-of-life status. In ROS Noetic, a total of 12 commits across ros/rosdistro implemented version updates, removals, and end-of-life tagging. In ROS 2 documentation, fixed a build-time issue by clarifying CMake target_link_libraries scope keywords to prevent ament_cmake build errors. These actions improved build reliability, reduced maintenance risk, and clarified deprecation timelines for downstream users.
