Sony has now released system update 4.50 for the PS4 console. The firmware is now available for you to download and comes with loads of new features.  The update itself is around 339MB and you should download it as soon as you see it. It should be available for every PS4 and PS4 Pro owner worldwide.  Arguably the best feature of this new update is that it allows console owners to now use an external hard drive. This is really helpful since every game now has mandatory installations and 500GB and 1TB aren't big enough.  External hard drives that are 250GB to 8TB are supported. Anything below or higher than these sizes will not work. It also has to be USB 3.0 for it to be compatible with your console.  Another cool feature is custom wallpaper. You can now customise your wallpaper with any screenshot you have saved from games you have played and more.  Other cool features include 3D Blu-ray movie playback for PlayStation VR owners and a Boost Mode on PS4 Pro. The Boost Mode increases the performance. To read about all the features, click here to see them all.
