We recently upgraded from 4.x (not sure exactly which version) to 4.3.5, and now the affiliate link structure has changed. Where before we had /go/?r=XXX representing the affiliate's ID, we now have /go/affiliatename/ It SEEMS to still track old style links, but can someone please confirm that is the case?
Yes, it still track old style links (backwards compatibility) We changed format of affiliate link to make it more user friendly and do not reveal internal user_id.
