To follow general best practices for Docker tagging, the latest tag for production images should no longer update when a new version is published: https://hub.docker.com/r/nanocurrency/nano/tags. This latest tag will be deleted from the Docker hub in the near future. However, the latest tag will be left available for the beta network tags to facilitate more passive contributions: https://hub.docker.com/r/nanocurrency/nano-beta/tags.
