Hi Andinet,
Thanks for reaching out!
Yes, we are actively working on switching to Humble. For the latest updates to ROS Toolbox, see the latest prerelease in the coming month (link to prerelease download page).
By the way, I saw you mentioned the generated code contains reference to rclcpp::Duration. Just to make sure we have taken care of it, would you mind elaborate more about which functions are you generating code from? A reproducible function/script would be even better.
Thanks,
Josh
