Release date: 2019-12-19 Docker TAG: 1912090356xb1e1fe, 2019-12-19T02:50:10 UTC

The following updates describe the latest improvements in each software package, which uses the following version sequence: loopchain 2.4.20, iconservice 1.5.20, icon-rpc-server 1.4.9, rewardcalculator 1.2.0.

docker-compose pull
docker-compose down
docker-compose up -d
