Check out the WP 4.7 release post for the full changelog.
One of the highlights of the release are the changes to the the WordPress Customizer, which was the first JS-driven WP Core feature. v4.7 brings improvements to this component with new edit shortcuts, direct page creation & custom CSS support.
After much debate, v4.7 includes REST API Content Endpoints for developers. The API opens up WordPress to mobile apps and other front end applications by making posts, terms & (limited) user data available in a standardized way.
