reworked the route concept; removed the idea of the localnet Renamed to reflect the actual meaning more clearly: s/online_routes/query_routes/g s/local_net_route/permanent_routes/g Removed local_nets, which are now represented by allowed_recipients in a permanent route. (See. examples/localnet.route) There is no more abiguity between `local' and `local net'. Run admin/config-transition on your config to learn how to update it.
