Getting Node-RED 5 in FlowFuse Community Edition

I've just started playing around with FlowFuse CE and I noticed that it is still running Node-RED 4.1.13. Is there some way to get 5.0.4? I tried the recommended upgrade instructions by downloading the latest docker compose yml file and then doing 'docker pull flowfuse/node-red:latest' but the version remained at 4.1.13.

there is an image tagged [latest-5.0.x]
