Change to licensing?

Since the last update (I think there was an update. I suddenly saw Event Driven and Integer modes.), I haven’t had to change my core device when moving back and forth from my home Macbook and my work computer. Was there a change to the number of core devices available? I only use Tidal on my work machine, so maybe I’m no longer required to be a core device to stream Tidal.

Are they running on the same network, meaning in a remote/core configuration? Or are they in different locations?
