3.0.0-RC2

Version 3.0.0-RC2 - August 20, 2019 (Maven)

Javadocs

Major change

After considering several factors, the components of RxJava 3 have been moved to a new base package to avoid class file conflicts due to having v2 and v3 in the same project. The new base package is io.reactivex.rxjava3 and the base types will live in io.reactivex.rxjava3.core:

Name	v2	v3
Base package	io.reactivex	io.reactivex.rxjava3
Flowable	io.reactivex.Flowable	io.reactivex.rxjava3.core.Flowable
PublishSubject	io.reactivex.subjects.PublishSubject	io.reactivex.rxjava3.subjects.PublishSubject
ConnectableObservable	io.reactivex.observables.ConnectableObservable	io.reactivex.rxjava3.observables.ConnectableObservable
Function	io.reactivex.functions.Function	io.reactivex.rxjava3.functions.Function
etc.

Flowables of the two versions can talk to each other without bridges because both implement the Reactive Streams' interfaces such as Publisher:

io.reactivex.Flowable.range(1, 10)
    .flatMap(v -> io.reactivex.rxjava3.core.Flowable.just(v * 10))
    .subscribeWith(new io.reactivex.rxjava3.subscribers.TestSubscriber<>())
    .assertResult(10, 20, 30, 40, 50, 60, 70, 80, 90, 100);

The other reactive types do not share such base interfaces (they have their own respective copies) and will require bridges, likely provided via 3rd party libraries as with v1->v2 or v1->v3 bridges.
