I've read through the upgrade patch section and it looks good to me, if you already have a WIP PR for it could you also share it here so that people can take a look? I'm +1 on the KIP itself. But large KIPs like this there are always some devil hidden in the details, so I think it is better to have the implementation in parallel along with the design discussion :) Guozhang On Wed, Mar 7, 2018 at 2:12 PM, Matthias J.
