Bloody hell, it's a long and winding road to firmware 5.0 isn't it? Sony's released yet another smaller PlayStation 4 software update in the form of version 4.73, which you can download and install right now. Don't get too excited, though -- this one's all about improving that "quality of system performance".
Firmware version 4.73 weighs in at around 341MB, and it's mandatory, meaning that you'll need to grab it if you want to get online with your console.
Update 5.0, meanwhile, will be entering its closed beta phase at some point this month. Its features still haven't been confirmed, although rumours have suggested that it's going to be a big one. We find some of them difficult to believe, however.
