Just curious about whether the major version upgrade on node-http-handler should result in a minor version change of the package... But since there are no changes in the exposed API, there is no need.

@rockaBe I think internally the entire smithy suite has upgraded to 2.x and the AWS SDK clients now require this new major version of smithy modules, that's all. For what it's worth, I didn't detect any exposed API changes either.
