I am not a DockerHub user myself, now that we have introduced branches to work on different version of the project:

(current state 21.06.2018)

• master for version 3.0.3-SNAPSHOT
• 3.1.x for version 3.1.0-SNAPSHOT
• 4.0.x for version 4.0.0-SNAPSHOT

See also: https://github.com/OpenAPITools/openapi-generator/wiki/Git-Branches

I am wondering how this works in DockerHub:
https://hub.docker.com/r/openapitools/openapi-generator-cli/tags/

"latest" tag seems to be the last built, regardless of the branch.

What would make sense?

• "latest" for latest from the master branch
• "latest_" in the other cases (for our protected branches like 3.1.x and 4.0.x - not for the working branches)
