+Version 0.20.0-RC2 preview release adds support for backpressure to the `zip` operators, fixes bugs and removes the `Subscribe.onSetProducer` method.
+
+This means signature changes are now:
+
+A new type `Producer` has been added:
+
+```java
+public interface Producer {
+    public void request(long n);
+}
+```
+
+The `Subscriber` type now has these methods added:
+
+```java
+public abstract class Subscriber<T> implements Observer<T>, Subscription {
+	public void onStart();
+	protected final void request(long n);
+	public final void setProducer(Producer producer);
+}
+```
