Hmm, either I failed at deleting, or someone/something pushed it. I’ve now deleted it again.
However, I don’t think it’s the cause of the issue in this topic.
That is very surprising. If you’re on tests-passed, it should be 3.4.0.beta1-dev right now!
In your /var/discourse/containers/app.yml file, have you customized the version: key at all?
