+- **Marks are now renderable as components.** Previously the only supported way to render marks was by returning a `style` object. Now you can return a style object, a class name string, or a full React component. Because of this, the DOM will be renderered slightly differently than before, resulting in an extra `<span>` when rendering non-component marks. This won't affect you unless you were depending on the DOM output by Slate for some reason.
