@stanleyyconsensys Is there any reason we wouldn’t simply update the previous one? Or were you concerned this might introduce a breaking change?

NVM, I see now that this isn’t the only change; the chainId is also being updated.

Yea, it is kind of a new network,
+
we try to avoid controller-utils breaking change, as it will introduce breaking change for many controllers
and soon we will introduce a new controller to store the information remotely
