title: Differences between RxJava1 and RxJava2
body: <p>I've been looking the documentations of RxJava1 <a href="https://github.com/ReactiveX/RxJava/releases">https://github.com/ReactiveX/RxJava/releases</a> and RxJava2 <a href="https://github.com/ReactiveX/RxJava/wiki/Reactive-Streams">https://github.com/ReactiveX/RxJava/wiki/Reactive-Streams</a> and seems like the unique different is that RxJava 2 has Java Stream.</p>
  
  <p>Any other different?.</p>
  
  <p>I've been working with Version 1.1.3 but I'm not sure if it's worth it move to RxJava2 since we're already using Java 8 streams in our code</p>
  
  <p>Regards.</p>
