Sony has released system software update 3.15 for the PlayStation 4, but don't get too excited as there's no major features in today's update.
According to the very brief notes, the system update "improves the quality of the system performance." That's all.
You can download the update here, or your PlayStation 4 should have already done so if you keep it in rest mode. It's around 260mb in size.
The PS4's last "major" update arrived in October and brought a number of new features including the ability to follow verified accounts of game studios and developers, and stickers! Everyone loves a good sticker. Prior to that, update 3.00 brought the ability to live stream gameplay to YouTube and increased online storage capacity for PS Plus, among other things.
