I look at what the change log says. I do not understand all the details ;-). If you look at Routing, it says that that module will be restarted when the node fails to join the network (probably in x-amount of time). So instead of just trying to reconnect over and over again, it looks to me as if the Devs tested it and found out that a restart of that module was a better idea. David pointed out a few days ago that they started the network several times on the Droplets:
So these sort of details is what I’m looking for. It seems they tested the nodes, found out a way to improve making connections to the network by restarting a module. But just like you I don’t know the details about versions.
