Due to the major update to version 1.5, I would like to know which version of the game the tournament will be played on. If it's the latest update, there are many changes, and I should withdraw from the tournament and just test the new version. I don't want to play in an unknown environment during a tournament. And lastly, what should I do if I've already updated? I accidentally clicked the update to the latest version today, and it started a massive installation. I assume there won't be a way to revert to the old version 1.4.2, right?
