The update itself didn't introduce any major changes to the interface or functionality, but I appreciate the continued support from Sony to keep my console up-to-date and secure.
If you need to update your PS4 to firmware version 9.00, don't hesitate to do so. The process is straightforward, and you'll have a more secure and stable console as a result. As always, make sure to back up your data and ensure your console is connected to a stable internet connection before starting the update.
Overall, I'm happy with the update process, and I'd give it a solid 5/5 stars. Kudos to Sony for making it easy to keep my PS4 up-to-date!
