 changes in the [Openapi file](./rpc/openapi/openapi.yaml)**.

-npm i -g dredd
-make build-linux build-contract-tests-hooks
-make contract-tests

+**WARNING: contract tests are currently not available. They previously depended 
+on a local network setup that has been removed due to maintenance issues. The

+validate API changes.
