Gran Turismo 5 has had something of an update. And it's a big one. The key details are as follows:Remote Racing – On the bottom left of the [GT Mode] - [Community] screen, [Remote Races] have been added. You can combine the "My Driver" of you and your friends to start a fully automatic B-Spec race, to gain rewards and experience.

There's more (see link at the bottom) but we really love:
" Game save speed has been optimised"
and...
"The HDD access warning message that was displayed at game startup has been disabled for faster startup."
and...
"Corrected an issue where the save data becomes unable to load when exceeding a certain file size."
