There are separate support for ROS2 Topics, Actions and Services.

Release of jros2client v3

Major update is support of ROS2 CycloneDDS RMW.

Details:
Previously rtpstalk supported only RTPS versions 2.2 and 2.3. CycloneDDS 0.9.x (Papillons), which is included into ROS2 Humble, uses RTPS 2.1. Because jrosclient relies on rtpstalk for RTPS communication, it could not interact with ROS2 nodes running on CycloneDDS RMW. Major change in jrosclient v3, is update to new version of rtpstalk, which now supports RTPS 2.1 and consequently allows jrosclient to interact with ROS2 CycloneDDS RMW.
