WhatsApp Support
Now you can send messages using WhatsApp instead of the default Messages app.
You do need to have the WhatsApp installed on your device to see this option. Also, the contact should be using the same phone number on WhatsApp for this to work.
Pointer Support for iPadOS 13.4
Starting in iPadOS 13.4, you can connect a trackpad or a mouse to your iPad, and use a pointer to navigate and manipulate the interface. With this update, we have added support for the pointer in Contacts Journal, so that most of the interface elements get a slight hover effect when the pointer passes over it, to show you where you can touch on screen.
