I have decided to create a thread with all or most of the upcoming 1.8 news. When you post on this thread make sure you know that the information is RELIABLE AND NOT FAKE. That means that if you find it on some random website that has nothing to do with gaming or minecraft, it could be fake.
Now the news:
In this picture you see a game-generated river. Notch has added rivers and will soon add game-generated waterfalls also. It looks really cool. He also added canyons and trench like things.
