[JiaqiangZhang]

Thanks for the repo!

Description:

When I try to use rosbag-tools topic-remove, it crashes with the following error:

rosbags.rosbag2.errors.ReaderError: Rosbag2 version 9 not supported; please report issue.

Environment:

OS: WSL2 Ubuntu 24.04

ROS 2 distribution: Jazzy

Python: 3.12

rosbag-tools installed via pipx

Steps to reproduce:

Run rosbag-tools topic-remove <bagfile> -t /topic

The command fails with the error above.

Expected behavior:

The tool should work with rosbag2 version 9, or at least provide clearer guidance on supported versions.

Additional context:

It seems that rosbag2 version 9 is not yet supported by rosbag-tools. Could you clarify if support is planned, or suggest a workaround?
