+### Version 2.1.1 - June 21, 2017 ([Maven](http://search.maven.org/#artifactdetails%7Cio.reactivex.rxjava2%7Crxjava%7C2.1.1%7C))
+
+#### Notable changes
+
+The emitter API (such as `FlowableEmitter`, `SingleEmitter`, etc.) now features a new method, `tryOnError` that tries to emit the `Throwable` if the sequence is not cancelled/disposed. Unlike the regular `onError`, if the downstream is no longer willing to accept events, the method returns false and doesn't signal an `UndeliverableException`.
+
+#### API enhancements
+
+- [Pull 5344](https://github.com/ReactiveX/RxJava/pull/5344): Add `tryOnError` to `create/XEmitter` API.
+- [Pull 5386](https://github.com/ReactiveX/RxJava/pull/5386): Add `subscribeOn` overload to avoid same-pool deadlock with create.
