PS4 Firmware Update 1.51
Within a week of the PS4 launch, it’s already getting it’s first firmware update. The PS4 FW update 1.51 will provide minor adjustments to the UI as well as a clearer definition of whether or not a game is downloading an update/patch to eliminate some confusion for users.
If you’re going to be at work all day, just leave your PS4 in standby mode and it will automatically download and install the update for you. It is launching in North America today. Not much else is known about specific tweaks to the UI, however the update is automatic and appears to be mandatory. As with the 1.50 update, it should not interfere with gameplay and should download right in the background.
