1.2.2 release preparations

[akarnokd]

Version 1.2.2 - November 3, 2016 (Maven)

Note that the interface Cancellable has been moved to rx.functions affecting CompletableEmitter and the experimental Observable.fromEmitter(Action1<AsyncEmitter<T>> emitter, AsyncEmitter.BackpressureMode backpressure) has been removed.

Another important clarification was added to the javadoc about using SingleSubscriber: due to the internal enhancements of Single, a SingleSubscriber is no longer wrapped into a Subscriber+SafeSubscriber which setup used to call unsubscribe on the SingleSubscriber yielding isUnsubscribed() == true when the source terminated. Therefore, when one extends the class SingleSubscriber, the unsubscribe() should be called manually to yield the given expecation mentioned before:

Subscritpion s = Single.just(1).subscribe(new SingleSubscriber<Integer>() {
    @Override public void onSuccess(Integer t) {
        System.out.println("Success");
        unsubscribe();
    }

    @Override public void onError(Throwable e) {
        e.printStackTrace();
        unsubscribe();
    }
});

assertTrue(s.isUnsubscribed());
