[quote="carlosjoserg, post:10, topic:4736"] For some reason, the bug fixed C3 was accepted in `kinetic` , but then cherry-picked/merged into `lunar` manually, that is, into a future release. [/quote] That is certainly not the normal flow. I am not sure of that is a real-world example (can you provide a link to a PR?) or just illustrating. I can't speak for all ROS repos but in `ros_comm` any PRs are only merged into the *latest* devel branch. The only very rare exception is if a patch is only necessary for an older distro but not the latest one. And then in a second step all changes on the latest devel branch are being considered for backport to the previous devel branch (and then from there to the second previous etc.). See https://github.com/ros/ros_comm/pull/1323 for an example of such a backport. So as far as I understand you proposal that is exactly what is happening in `ros_comm` with the only exception that the "single line of development" is not named `master` but after the latest ROS distro. I would suggest to continue this specific conversation in a separate topic / thread since it gets a little bit away form the scope of the original topic. --- [Visit Topic](https://discourse.ros.org/t/proposed-changes-to-the-ros-releases/4736/12) or reply to this email to respond.
