We are planning to break ABI on message_filter I created this PR https://github.com/ros-perception/perception_pcl/pull/457 to fix the build job but I can see an issue in rosdistro. There are branches for `humble`, `iron` and `rolling (ros2 branch)` but all rosdistro distributions are pointing to the `ros2` branch - rolling https://github.com/ros-perception/perception_pcl/commits/humble/ - jazzy https://github.com/ros/rosdistro/blob/master/jazzy/distribution.yaml#L4417-L4421 - iron https://github.com/ros/rosdistro/blob/master/iron/distribution.yaml#L4381-L4385 - humble https://github.com/ros/rosdistro/blob/master/humble/distribution.yaml#L5637-L5641 But I also check that there are some activity at least on the `humble` branch. I would love to hear from the maintainers what to do here. - override `humble`, `iron` and `jazzy` with the actual `ros2` branch? and update rosdistro ? but this might destroy some work done for these old distros - create a new branch for humble iron and jazzy based on `ros2` and then continue working on ros2 - any other ideas ?
