I bought my OWE a few days ago, and I have the latest rules in hand. I also bought one of these the year before. Other than the maximum of 20 segments overall, and the switch from M to L for economy fares, I don't see major changes. The old rules have the right info regarding limitation on USA transcons, Australia flights to Darwin and Perth, 2 stops in continent of origin, extra transit stop between continents in NA & Asia, etc.. Until someone points you at a copy online, if you have a question ask here.
