The new v1.1 specification for LoRaWAN has been released. There are quite a few changes, adding additional security and better roaming support. If you're developing end devices for our network, you might want to ensure you're aiming for the new 1.1 spec, to gain all of these benefits.
Don't worry though, we'll still support any LoRaWAN 1.0.x devices for a good while yet!
