Duplicacy Web on Docker, not upgrading to v1.6

[truthsword]

I’m running the following docker-compose (volumes/registration omitted)

version: "3"
services:
  duplicacy-web:
    image: saspus/duplicacy-web:mini
    container_name: duplicacy-web
    environment:
      - DUPLICACY_WEB_VERSION=Stable

I understood (misunderstood?) that stopping the container and and restarting the compose file would force an update when using the “mini” image. Yet I am still on v1.5.0.

What am I overlooking? Thank you.
