Haven’t updated for the firmware for quite some time, but nothing notable new features have been introduced since 3.55, because SONY has been busy combating with hackers. But thanks to that we all get some free games.
3.55 and 3.56 are pure security patches to disable jailbreak.
3.60 adds online storage (manual) and controller save setting.
3.61 forces user the PSN login password after the infamous hacking which caused the network down for almost two month.
3.65 and 3.66 are security patches as well. 3.65 is not mandatory, while 3.66 is, not sure what new has been added.
