-> This library is currently in preparation for v0.5 with many breaking changes. For the documentation of the current crates.io v0.4.0, visit the [docs](https://docs.rs/ros_pointcloud2/0.4.0/ros_pointcloud2/). Since rclrs still needs a workaround, the version number must be changed to your desired version which supports rclrs (currently only v0.4.0) — regardless of the version number shown in this Readme.
