Ok, I did the update last night and when it restarted it failed to connect to the network. I tried a few times and couldn't get on. So I went into network connections and tested the connection and it said failed. So I went into Internet connections and went through manually, just making sure everything was the same and hadn't changed. At the end it promps you to test the connection again. So I did and it worked. It also had added a speed test for upload and download speed.
Signed in and had one race with some noob from GB who was taking people out at the end of the straight at Fuji.
So it is probably better you don't go on ;P
