Seeing as I've answered a few questions on ROS Answers just by pointing to this issue, I think it makes sense to forward it to this list as well. Gijs -------- Forwarded Message -------- Subject: [ros-sig-robot-control] Critical bugfix: Avoid control_toolbox 1.13.1 Date: Fri, 22 May 2015 17:50:54 +0200 From: Adolfo Rodríguez Tsouroukdissian To: ros-sig-robot-control@googlegroups.com , ros-users All, If you use control_toolbox in indigo or jade, read on. A critical bug has been identified in the PID implementation of control_toolbox 1.13.1, and fixed in 1.13.2 [1]. This bugfix is important because if the bug is triggered, it can make hardware unstable. What to do: - Indigo users: Stay on 1.13.0 or lower, or wait for 1.13.2, which has just been released (it might take some days for the binaries to churn out). - Jade testers: Build from source, or wait for 1.13.2 to make it through. - Folks building from source: Avoid working on bc45790 [2], preferably pull the latest changes. - Hydro users are unaffected. As to how long the bug has been out there: 1.13.1 was released on April 30, 2015, but announcement of the indigo sync took place yesterday, on May 22. Best regards, and sorry for the inconvenience.
