Sony has announced that the PS4 firmware update 1.50 has now been released in preparation for Friday's North American release.
As well as addressing a few short fixes, the firmware update enables many of the console's promised features. These include, Remote Play, Second Screen, Content Sharing, Broadcasting/Spectating Gameplay, Play as you download and Party Chat.
Remote Play is one of the core features for the PS4, although it does require access to a PS Vita too. It enables you to play your PS4 games on the PS Vita, which is a huge selling point for the console.
Second Screen works with the PS Vita too, allowing you to use the Vita as an additional screen. Many games have been using this kind of technology with tablets, so adding support for the PS Vita is a bonus.
Party Chat is a feature that's been long requested. By using the headset bundled with the PS4, you'll be able to chat with up to 8 different people. You'll also be able to speak with people who're using a PS Vita.
You will be able to download this using the PS4's system network update, but there should also be a file contained on game discs that arrive around launch. Alternatively, you can upgrade via USB.
