How does the Buddypress connector work?

I believe, based on what I read about recent updates, that the plugins are now part of the core code, so I’m asking in the Core category. I apologize is this is incorrect. I would, however, like to know what changes are made and how to use the Buddypress connector. I have activated it, but there don’t appear to be any changes, new options, additions or anything really.
Am I missing something?
