+### Version 1.3.0 - May 5, 2017 ([Maven](http://search.maven.org/#artifactdetails%7Cio.reactivex%7Crxjava%7C1.3.0%7C))
+
+#### Summary
+
+Version 1.3.0 is the next minor release of the 1.x series of RxJava containing many formerly experimental API components promoted to standard. Most notably the `Completable` base reactive type is now standard as well.
+
+Note that the experimental `rx.Observable.fromEmitter()` has been removed in favor for the now also standard `Observable.create(Action1<Emitter<T>> emitter, Emitter.BackpressureMode backpressure)`
+
+The planned lifecycle of the 1.x line is as follows:
+
+Date | Remark

+
+**Operators**
+

+- `CompositeException(Throwable...)` constructor
+- `Exceptions.throwOrReport` (4 overloads)
+- `BlockingObservable.subscribe` (6 overloads)
