=====

I think it’s a much better result compared with previous chaos(random staging, and many client lost and etc). I didn't plan to provide an overview of that period yet.

I am not very sure the progress of ci/coin team, see http://lists.qt-project.org/pipermail/development/2018-November/034244.html .

During this period, nobody contacted me to stage their change. So my staging is just based on the history of previous failures.
