RFC #42 is RFC 8342

My 42nd RFC has been published and it got the number RFC 8342. Despite the funny number, I believe this is one of the more important RFCs I have worked on since it tells us how to think about configurations and their relationship to operational state. A few more RFCs will appear during the coming weeks providing the technology extensions that allow us to use the new framework in practice. Work on this document started with a trip to Stockholm in May 2016 but the discussions have a much longer history and it feels good to have them settled and the document published.
