Rockstar has just announced that the first update for the recently released L.A. Noire has gone live on the PlayStation 3 and Xbox 360. It's been dubbed the title update, and is v1.00.
The game fixes several bugs, but there's nothing that major. One of the changes, for example, fixes a bug with the age verification on DLC in the in-game store. Stat tracking has also been improved.
L.A. Noire has been catching all the headlines for mostly the right reasons, although there were some cases of PS3s dying when playing the game - there's no real idea what's causing it though.
