A new Neural networks API is baked in, for example, providing hardware acceleration of on-device machine learning. Apps can only make a notification alert sound once per second, improved targeting for low-RAM devices is built-in, and the Autofill framework gets support for custom descriptions that let developers mask credit card numbers, and only show the last four digits.
