When I tested upgrading from 4.2.2 to 5.0.0, I found that both 4.2.2 and 5.0.0 workers can mix together connecting to 5.0.0 ATC. But
fly shows both workers as version 2.1.
name containers platform tags team state version worker-PxVUvVtow 5 linux none none running 2.1 worker-wyaIogcem 13 linux none none running 2.1
Does worker has a separate versions than concourse?
