 # RxJava Releases #
 
 Version 1.x can be found at https://github.com/ReactiveX/RxJava/blob/1.x/CHANGES.md
+
+### Version 2.0.0-RC1 - August 25, 2016 ([Maven](http://search.maven.org/#artifactdetails%7Cio.reactivex.rxjava2%7Crxjava%7C2.0.0-RC1%7C))
+
+RxJava 2.0 has been rewritten from scratch to be more performant, lower overhead (memory and cpu) and to natively implement the Reactive-Streams specification in its new `Flowable` type. The library still supports Java 6+ and is considered a **4th generation reactive library**.
+
+There have been hundreds of PRs and large amounts of changes compared to the 1.x version. The two are binary-incompatible but their distinct maven coordinates (`io.reactivex.rxjava2:rxjava:2.0.0-RC1`) allow them to co-exist. You can use the [rxjava2-interop](https://github.com/akarnokd/RxJava2Interop) library to convert between 1.x and 2.x types.
+
+Please refer to the [wiki page about the differences between the two major versions](https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0).
+
+Converting the companion libraries is an ongoing effort. For now, see the [rxjava2-extensions](https://github.com/akarnokd/RxJava2Extensions) project that contains the port of the [RxJavaMath](https://github.com/ReactiveX/RxJavaMath) features. Note that most companion libraries of RxJava are currently not set up properly for release (the signing keys are missing from the CI release process) and is unknown if and when they will have their own 2.x release branch.
+
+I'd like to thank for the contributions of the following community members (in LIFO commit-merge order):
+
+@davidmoten, @JakeWharton, @vanniktech, @dimitar-asenov, @artem-zinnatullin, @bobvanderlinden, @DmitriyZaitsev, @zsxwing, @bcorne, @stevegury, @benjchristensen, @stealthcode, @adam-arold and @abersnaze.
+
+A special thanks goes out to @smaldini, [Project-Reactor](https://github.com/reactor/reactor-core) lead at Pivotal. Our ongoing cooperation lead to the massive improvement of the RxJava 2.x architecture (originally designed in August 2015) by learning from and building upon the results of the [Reactive-Streams-Commons](https://github.com/reactor/reactive-streams-commons) research project.

 # RxJava: Reactive Extensions for the JVM

 RxJava is a Java VM implementation of [Reactive Extensions](http://reactivex.io): a library for composing asynchronous and event-based programs by using observable sequences.
 
 It extends the [observer pattern](http://en.wikipedia.org/wiki/Observer_pattern) to support sequences of data/events and adds operators that allow you to compose sequences together declaratively while abstracting away concerns about things like low-level threading, synchronization, thread-safety and concurrent data structures.
 
 #### Version 2.x
 
-Version 2.x and 1.x will live side-by-side for several years. They will have different group ids (`io.reactivex.rxjava2` vs `io.reactivex`) and namespaces (`io.reactivex` vs `rx`). 
+- single dependency: [Reactive-Streams](https://github.com/reactive-streams/reactive-streams-jvm)  
+- continued support for Java 6+ & [Android](https://github.com/ReactiveX/RxAndroid) 2.3+
+- performance gains through design changes learned through the 1.x cycle and through [Reactive-Streams-Commons](https://github.com/reactor/reactive-streams-commons) research project.
+- Java 8 lambda-friendly API
+- non-opinionated about source of concurrency (threads, pools, event loops, fibers, actors, etc)
+- async or synchronous execution
+- virtual time and schedulers for parameterized concurrency
 
-The purpose for 2.x is:
 
-- continued support for Java 6+ & [Android](https://github.com/ReactiveX/RxAndroid) 2.3+
-- [Reactive Streams](http://www.reactive-streams.org) compatibility
-- performance gains through design changes learned through the 1.x cycle
+Version 2.x and 1.x will live side-by-side for several years. They will have different group ids (`io.reactivex.rxjava2` vs `io.reactivex`) and namespaces (`io.reactivex` vs `rx`).
