dgram is at 90% compatibility, and all of the methods listed in the advanced dgram methods issue[0] have been implemented in 1.2. The url package has currently only one unimplemented test out of 13. If you've had any issues with dgram in 1.2, open an issue in our repo and I'll take a look :)
Well, I can now actually _run_ Node-RED 4.0 and receive multicast UDP packets, so that's great. I will be testing it with more complex stuff soon, and let you know.
