@sivaGH3 we usually dont release for existing released versions as we follow semver[1]. Can you consume latest 1.x ?
@wbeckler do we do anything different with clients?

@saratvemulapalli , how to consume latest 1.x, what are the steps? thanks!

I think you'll have to build and consume a private jar for anything that's no longer supported, https://stackoverflow.com/questions/4955635/how-to-add-local-jar-files-to-a-maven-project. Does this work?
