    💥 BREAKING CHANGES

    • 👻 Notification: Notification.prototype.exception is now Notification.prototype.error to match Rx4 semantics
    • Symbol.iterator: RxJS will no longer polyfill Symbol.iterator if Symbol does not exist. This may break code that inadvertently relies on this behavior
    • Object.assign: RxJS will no longer polyfill Object.assign. It does not require Object.assign to function, however, your code may be inadvertently relying on this polyfill.
    • 👍 AjaxObservable: Observable.ajax.getJSON() now only supports a single type parameter, getJSON<T>(url: string, headers?: Object): Observable<T>. The extra type parameter it accepted previously was superfluous.
    • 🚚 distinct: distinctKey has been removed. Use distinct
    • distinct: distinct operator has changed, first argument is an optional keySelector. The custom compare function is no longer supported.
