Minor fixes from RxJS v2.2.15 to include bug fixes and changes to Enumerable to make it ES6 compatible.
From Iterable
This release has a new function which makes it ES6 compatible with iterables. We now have Rx.Observable.fromIterable
method which takes in an iterable and converts it to observable sequence.
var set = new Set([1,2,3]);
var observable = Rx.Observable.fromIterable(set);
var subscription = observable.subscribe(console.log.bind(console));
// => 1
// => 2
// => 3
