Please remember that this is the first driver with the new codebase. If you're having bugs, there is a good chance that they get fixed in 8.42 or later. Don't post "AMD sucks" when you have one new bug. Why I am posting this? Because I bet some people will be posting "AMD doesn't care for community support - I have a new bug!!1111".
I would say it's 3.5h from now but Michael said it comes a bit earlier... let's see.
