That is the latest released version, and yes, it still works just fine.
You mentioned GatherMate, so I'll assume you're using that. You need some data in your GatherMate database, so either go fly around and populate it yourself, or import node data from GatherMate_Data. Once that's done, you should be able to create a route in Routes using data from GatherMate.
ahh ok, sorry for my noobishness lol, routes was one of my most valued addons in bc, just hoping i can get it to work for wrath :D kudos to the author its one of my top 3 addons right up there with atlas loot and xperl :D
i must be doing something wrong trying to get it to load the gathermate data base :/
hmm ill go check again
