@Ladicek @mkouba @manovotn asking for your review as I had to change something in ArC (more info in the commit message)

@Ladicek pinging you also because you might need to adjust the Gizmo 2 port if we merge this.

[Sanne]

Good catch, this would be important indeed

I think we are good to go now, as far as CI is concerned.
Once this is in, I'll make the necessary doc changes and also changes to our tooling.
