Version 1.47.4
--------------

- New JavaScript feature: ES6 Promises. This release includes Lie [1], a small,
  self-contained Promise implementation, which is imported automatically to
  form the Promise global object [2]. In the future, Promises will be built into
  the SpiderMonkey engine and Lie will be removed, but any code using Promises
  will continue to work as before.
