0.27.0 (EOL)

End-of-Life (EOL) version

Adds Scala 2.13 support.

Note on compatibility:

• Binary compatibility with 0.26.5 for Scala 2.10 - 2.12
• The Scala major version Seq is used, so scala.collection.generic.Seq for 2.10-2.12 and scala.collection.immutable.Seq for 2.13
• Some methods which take an implicit CanBuildFrom[Nothing, ...] in the 2.10-2.12 version take an implicit Factory in the 2.13 version to follow the collection re-design.

0.26.5

The most notable change is adding SyncOnSubscribe and AsyncOnSubscribe support. Search them in RxScalaDemo for examples. RxJava and Scala are upgraded to the latest version as well. Check the following section for other changes.

0.26.2

This release upgrades RxJava to 1.1.6 and adds the new experimental ErrorDelayingObservable class.

What is the new ErrorDelayingObservable class?

ErrorDelayingObservable contains a variety of operators that support delaying errors. Sometimes when you compose multiple Observables together (e.g., flatMap, concat), you may want to refrain from propagating error notifications until all of the Observables have finished emitting items. In such cases, you can call Observable.delayError to get an ErrorDelayingObservable and use the ErrorDelayingObservable's methods to compose your Observables. Search for delayError in RxScalaDemo.scala for examples.

0.25.0

This release upgrades RxJava to 1.0.11 along with the following enhancements:

• Deprecate ExperimentalAPIs and use @Experimental/@Beta annotations directly. Unstable APIs wil be labeled Experimental/Beta in Scaladoc.
• Change error[T] to error: Observable[Nothing]
• Add TestSubscriber and its examples. Writing unit tests is much easier now. See TestSubscriberExample for examples.
• Add onBackpressureLatest and variants of flatMap and using.
• Add more experimental methods of Subject.
• Move examples to examples package: https://github.com/ReactiveX/RxScala/tree/0.x/examples/src/test/scala/examples
• Some document fixes

Migration from 0.24.1 to 0.25.0

Observable.error does not have a type parameter any more. Please remove the type parameter of Observable.error in your codes.
Sometimes removing the type parameter may break your codes. E.g.,

val x = Observable.error[Int](new RuntimeException("Oops")).toBlocking.single
println(x + 1)

It won't be compiled if Int is removed. For these cases, you can add the explicit type to the variable and make the compiler happy, such as

val x: Int = Observable.error(new RuntimeException("Oops")).toBlocking.single
println(x + 1)

ExperimentalAPIs is deprecated. It's not a breaking change, but we plan to remove ExperimentalAPIs in 0.26.0. If you are using ExperimentalAPIs,
please recompile your codes and fix them as per the deprecated messages provided by the compiler as soon as possible. Once ExperimentalAPIs is removed,
you won't get the deprecated messages.
