 # RxJava Releases #
 
+### Version 0.16.0 ([Maven Central](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.netflix.rxjava%22%20AND%20v%3A%220.16.0%22)) ###
+
+
+This is a significant release with the following changes:
+
+- Refactor of Subjects and Subscriptions to non-blocking implementations 
+- Many bug fixes, new operators and behavior changes to match Rx.Net. 
+- Deprecation of some operators due to renaming or eliminating duplicates 
+- The `rx.concurrency` package has been renamed to `rx.schedulers`. Existing classes still remain in `rx.concurrency` but are deprecated. Use of `rx.concurrency` should be migrated to `rx.schedulers` as these deprecated classes will be removed in a future release. 
+- Breaking changes to Scala bindings. See [Release Notes](https://github.com/Netflix/RxJava/blob/master/language-adaptors/rxjava-scala/ReleaseNotes.md) for details.
+- New modules: rxjava-string, rxjava-async-util and rxjava-computation-expressions for operators deemed not applicable to the core library.
