InfernoJS v9.0.0

Breaking changes

inferno-create-class has been removed, use createComponentVNode, createElement APIs instead. If you were using createClass to wrap the class into observable you can do the same by extending inferno component.

observer(
  class MyCom extends Component {
    componentWillReact() {
      willReactCount++;
    }

    render() {
      return (
        <div id="x">
          {[foo.a.get(), foo.b.get(), foo.c.get()].join(',')}
        </div>
      );
    }
  },
);

Inferno v9 requires following features to be present in the executing runtime:

• Promise
• String.prototype.includes()
• String.prototype.startsWith()
• Array.prototype.includes()
• Object.spread()

options.componentComparator has been removed options.renderComplete has been removed, same result can be achieved by calling own function after render
