PlayStation 4 PS4 Firmware Update 4.06 Sony 1

PlayStation 4 firmware update v4.06 has put in a surprise appearance today, and rather than stabilising the system, it promises to improve the "quality" of your console. We're not entirely sure what that means, but okay. The update weighs in at 312.3MB, so it isn't exactly going to break through your bandwidth cap.

It is mandatory, however, so you'll need to have it installed if you want to play online. Remember, you can set your console to update in Rest Mode by following these instructions. Do let us know if you've noticed any improvements in the comments section, but this is likely to be under-the-hood stuff. Perhaps it's paving the way for PlayStation Network name changes?
