One notable feature introduced in 5.50 (including library UI updates, enhancements to the quick menu, and customizable wallpapers) is playtime management, which allows family members to manage playtime for younger PS4 users.
Play Time Management allows adults that have guardian privileges on the system to set time limits on how long children can play the console.
The family manager/guardian can log into the account and set the playable hours. Notifications are sent to children while they're playing, giving them a heads-up on when they should save or quit because their playtime is set to end. What the latter includes is obvious, but the new parental settings let parents limit how much child accounts can play for day. With supersampling mode, games that render to a higher resolution when connected to a 4K TV will downscale to match the HDTV - allowing PS4 Pro owners to leverage the benefits of an image clarity boost even if they don't own a 4K TV. PS4 Pro users also get a new "supersampling mode" under settings to deliver better visuals for TVs with a 1080p resolution or less.
Two new tabs have been added to the library to make navigation easier. There's also a section where you can see which games you only "own" through PlayStation Plus. Some PS Now games will also let you listen to your own tunes while streaming a classic title from Sony's servers. As someone who participates in numerous betas, trials, and demos, my library is a mess - filled with applications I'll never use more than that initial period.
By popular demand, you can now import your own images via USB stick to use as custom wallpapers on PS4. Following this, Sony details several of the UI improvements coming in Update 5.50, starting with a "This PS4" tab that lists all applications installed on a PS4, and a tab with players' names/avatars showing all apps purchased with their PSN ID. The main new feature seems to be a slightly updated design, and a giant "NEW" on the front of the box, lest you forget for a few minutes that this was in fact an item fresh off the production line.
The mightily useful Quick Menu is also receiving some quality-of-life improvements, including the ability to quickly access specific friends in your custom list via the pulldown menu under the Friends tab. Once imported, you can even zoom, crop and preview them in-situ to help get the flawless look on your dashboard. When listening to Spotify on PlayStation Music, the Square buttons act as the shortcut for volume control. This is found under Settings Themes Select Theme Custom Select Image USB Storage Device.
Making this the third PS4 firmware in a row to tackle the notification menu, this update will allow you to delete old notifications, either individually or in bulk. Sony notes that, just like when playing a game locally on PS4, some background music may not always be available.
