They demonstrated the engines re-lighting in space, which is significant. There had been some questions about this because the engine is of a design that is said to be very tricky to start, and the tank pressurization system of the rocket has the risk of water and CO2 ice forming in the methane tanks, which had caused several failures in past tests flights. So this is a pretty good milestone.
So we might start seeing test flights actually entering orbit soon. Possibly even carrying some real payloads soon.
