Moxi ubuntu packages

Trying to find available deb moxi packages (built from https://github.com/couchbase/moxi)

Looking for version 4.0.0 based on the tags/releases on the github repo, I’ve only found a deb for version 4.6.0 but unable to find debs for earlier versions.
https://packages.couchbase.com/releases/moxi/4.6.0/moxi-server_4.6.0-ubuntu14.04_amd64.deb

Are these listed anywhere? Do not see any moxi packages available on https://www.couchbase.com/downloads
