UBR-1 on ROS2 Humble
The latest ROS2 release came out just a few weeks ago. ROS2 Humble targets Ubuntu 22.04 and is also a long term support (LTS) release, meaning that both the underlying Ubuntu operating system and the ROS2 release get a full 5 years of support.
Since installing operating systems on robots is often a pain, I only use the LTS releases and so I had to migrate from the previous LTS, ROS2 Foxy (on Ubuntu 20.04). Overall, there aren’t many changes to the low-level ROS2 APIs as things are getting more stable and mature. For some higher level packages, such as MoveIt2 and Navigation2, the story is a bit different.
