Some of the new features coming to PS4 with the next major system software update, version 4.50 (codenamed Sasuke), include support for external hard disks along with a "Boost Mode" feature for the PS4 Pro.

Sony is refining the user interface of PS4 even further, and is adding features like external HDD support and custom wallpapers.

It's easy to upgrade the HDD that came with your PS4, but if you're still looking for more storage space on the console, Sony has got you covered. With this update, you have the option to store content to an external HDD. Just plug a USB 3.0 HDD into your PS4, and you now have more space on the console.

This is compatible with HDDs up to 8TB in size. You can download and install applications directly to your extra storage, and the saved contents are easily manageable through the settings menu.

The PS4's latest firmware update will also feature a "boost" mode, which applied to the PS4 Pro model. The feature will be available in the settings menu. When activated, it will let PS4 Pro run at a higher GPU and CPU clock speed in order to improve gameplay on some PS4 games that were released before the launch of PS4 Pro. This means that games that have a variable frame rate may benefit from a higher frame rate, and load times may be shorter in some games too.

Also, all the applications saved in the external HDD will appear in the Content Launcher of the Home Screen.

This update also adds the ability to set your favorite in-game screenshot as the background image for PS4's home screen. Drop-shadows on text, and the option to dim the Function Area, will help keep the system icons and texts on the home screen clearly visible even if the background image you selected is super bright.

In the last system update Sony overhauled the PS4 Quick Menu feature (the menu that appears after a long press of the PS button on DualShock 4).

This update brings additional improvements to make it even more accessible. Now the Quick Menu will cover even less of your gameplay screen, and you'll be able to access handy Party features via Online Friends, like creating new parties, inviting friends, and joining parties, without transitioning to the separate Party app. The goal is to keep you in the game - and not stuck in menus.

Before this update, the Notifications app had a variety of tabs on the left-hand side, like Game Alerts, Downloads, Uploads, and more. Sony has condensed all of the tabs to a single simplified list, making it easier to see all of your notifications all at-a-glance.

In addition, Sony is adding the ability to post directly into the Activity Feed, which appears in a variety of places across the console, including What's New. Under What's New, you'll see a new option to post things like text, screenshots, and gifs directly into your Activity Feed. You can also tag games or other users to make sure they don't miss your post.

Tying into this new feature, Live from PlayStation will show screenshots that users uploaded to PSN as a Public Activity, so you can show off your best gameplay moments not only to your friends, but to users around the globe.

Last but not least, if you're a fan of 3D movies, and you own PlayStation VR, this update adds the ability to view 3D movies in stereoscopic 3D directly on the PS VR headset.
