Add new version to package.json:

• cash36-admin-frontend
• cash36-frontend
• cash36-compliance
• cash36-exchange

And rebuild dependencies and stubs (eventually set NPM_TOKEN=...2bb)

( cd cash36-admin-frontend; git pull; nvm use lts/dubnium; yarn; ) ( cd cash36-frontend; git pull; nvm use lts/dubnium; yarn; ) ( cd cash36-exchange; git pull; nvm use lts/dubnium; gradle build; gradle genToken36Controller genCash36Exchange ;gradle test ) ( cd cash36-compliance; git pull; nvm use lts/dubnium; gradle build; gradle genCash36Compliance genCash36Company; gradle test )

Push & merge to master to create new docker images, test local installation with cd cash36-docker docker-compose up
