Changelog for package jsk_rosbag_tools

3.0.0 (2026-10-29)

• Merge pull request #1826 from k-okada/ros2-support Add ROS2 support to jsk_ros1_ros2_compat, dynamic_tf_publisher, jsk_topic_tools, jsk_tools, audio_video_recorder, jsk_data, image_view2, jsk_rosbag_tools
• [jsk_rosbag_tools] add ROS2 support Single package.xml/CMakeLists.txt branched on $ROS_VERSION (ROS1-original lines inside the if("$ENV{ROS_VERSION}" ...) blocks, including catkin_download(...), left at their original indentation to minimize diff against master). Adds rosbag_compat.py, a local rosbag1/rosbag2 (sqlite3-backed) compat shim, and rewrites bag_to_audio.py/compress.py/ extract.py/info.py/merge.py/video.py/tf_static_to_tf.py as single ROS1/ROS2 dual-support scripts on top of it.
