I recently installed Bitcoin Core 32.0rc2 on one of my nodes and noticed that the reported P2P protocol version changed from 70016 to 70017.
I remember 70016 being used for quite a long time, so I was curious what exactly triggered the protocol version bump.
What changed in protocol version 70017 compared to 70016? Also, how does a 70017 node behave when connected to a peer that only supports 70016?
