Starting from iOS 12.4 onwards all iPhone migrations will be much easier. Instead of restoring a backup from iTunes or iCloud, iOS is now able to wirelessly migrate data from your old device to your new iPhone during the setup process of your latest acquisition. The two terminals have to be connected to the same WiFi network for the data transfer to work.iOS 12.4 Extended Software Update Log

Many of us expected the Apple Card service to be included in this last major iOS 12 update. However, Apple seems to have decided to postpone it a bit more. The Apple Card is a credit card developed by Apple, primarily designed to be used in conjunction with Apple Pay on compatible devices like the iPhone and Apple Watch. However, the Apple Card won’t be used only for digital payments. You will also get a titanium-made physical card that you can use in the stores like any other credit card.
