[Ridhwanluthra]

I have personally found whycon markers to be great and was wondering if there is any plan to build support for future versions of ROS?

Hello. I'm not currently working on this project for some time now and cannot really commit to maintaining it for current versions. However, I'm willing to accept pull requests to address specific issues impeding its use on newer ROS versions.
