This change removes the separate getter and setter methods and is causing a lot of errors. To fix errors you'll now need to use the actual field name. Example: OLD: $reader->getTournament()->getRounds()[0]->getGames()[0]->getBlack()->getPlayer()->getName(); NEW: $reader->Tournament->Rounds[0]->Games[0]->Black->Player->Name;
