Paper has been updated to bring faster and more precise inks for the Apple Pencil on the iPad Pro. The various tools have been optimized to be more responsive and quicker.
Using the Apple Pencil now seems to fully support pressure and angles much better. So, now, when you use a pen tool, the more pressure you apply, the heavier the ink flow. Also, when holding a pencil at an extreme angle, the shading feature works quite well.
The app now fully supports the new iPad Pro 9.7 inch model.
