Focus Areas
Please focus testing on the following areas:
• Please test general website compatibility.
• Subpixel rendering is now on by default for all web content. Websites or
in-app web views with extremely tight design constraints may render
differently.
• CSS object model getters will return fractional double values based on
subpixel layout and rendering metrics instead of rounded integral values. • Please test extension compatibility.
New WebKit Features
• WebGL. Safari support for WebGL allows developers to create 3D experiences that work natively without plug-ins.
• IndexedDB. The IndexedDB API allows web developers to store structured data for web applications that work online or require large amounts of data to be cached client side.
• JavaScript Promises. Safari enables JavaScript authors to work more naturally with asynchronous programming patterns.
• CSS Shapes and Compositing. Using CSS, websites can now easily flow text around images and geometry shapes, and perform image compositing operations on DOM elements.
