2.2.3

This patch release fixes an issue with builds where the source code uses ES2015 features (like template literals) and the forceES5 flag is set to false, like:

let name = "John";
let time = "today";

export default `Hello ${name}, how are you ${time}?`

This was caused by the transpile package using an old version of estraverse that did not support AST nodes like TemplateLiteral.
