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.
