-### Version 2.0.0-RC1 - August 25, 2016 ###
-
-RxAndroid 2.0 has been rewritten from scratch to support RxJava 2.0.
-
-The library still offers the same APIs: a scheduler and stream cancelation callback that know about
-the main thread, a means of creating a scheduler from any `Looper`, and plugin support for the
-main thread scheduler. They just reside in a new package, `io.reactivex.android`, and may have
-slightly different names.
-
-For more information about RxJava 2.0 see
-[its RC1 release notes](https://github.com/ReactiveX/RxJava/releases/tag/v2.0.0-RC1)
+Schedulers created via `AndroidSchedulers.from` now deliver [async messages](https://developer.android.com/reference/android/os/Handler.html#createAsync(android.os.Looper)) by default.
+This is also true for `AndroidSchedulers.mainThread()`.
 
+For more information about RxJava 3.0 see [its release notes](https://github.com/ReactiveX/RxJava/releases/tag/v3.0.0).
