Meteor 3.1: Documentation of roles integration

Just saw in the Meteor 3.1 change logs that the roles package has been integrated into the core. That’s amazing. However, I could not find any documentation on this. Is it just a 1:1 integration of the alanning:roles package, or were there made significant changes?

Ah, ok. Found it: Roles | Docs

Would be great to link it from the change log.

I am missing documentation about how the new core package differs from alanning:roles@4.0.0, though. Can it just be replaced without any modifications? The docs only mention upgrading from alanning:roles@3.6.
