0.24.0

This release adds ExperimentalAPIs to support Experimental/Beta APIs in RxJava, removes def onErrorResumeNext[U >: T](resumeSequence: Observable[U]): Observable[U]
to solve an ambiguity issue when using partial functions, and upgrades RxJava to 1.0.7.

ExperimentalAPIs

Now you can import rx.lang.scala.ExperimentalAPIs._ to use some unstable APIs which depends on Experimental/Beta APIs in RxJava. E.g.,

import rx.lang.scala.Observable
import rx.lang.scala.ExperimentalAPIs._

val o1: Observable[Int] = Observable.empty
val o2 = Observable.just(1, 3, 5)
val alternate = Observable.just(2, 4, 6)
o1.switchIfEmpty(alternate).foreach(println)
o2.switchIfEmpty(alternate).foreach(println)

See more examples in ExperimentalAPIExamples

Because the APIs in ExperimentalAPIs depends on unstable APIs in RxJava, if you would like to use a custom RxJava version,
it's better to check the compatibility in https://github.com/ReactiveX/RxScala#versioning

onErrorResumeNext

def onErrorResumeNext[U >: T](resumeSequence: Observable[U]): Observable[U] is removed to solve an ambiguity issue when
using partial functions.

Now you can use partial functions in onErrorResumeNext. E.g.,

val o = Observable { (subscriber: Subscriber[Int]) =>
  subscriber.onNext(1)
  subscriber.onNext(2)
  subscriber.onError(new IOException("Oops"))
}
o.onErrorResumeNext {
  case e: IOException => Observable.just(20, 21, 22)
  case _ => Observable.just(10, 11, 12)
}.subscribe(println(_))

0.23.0

This release upgrades RxJava from 1.0.0-rc.5 to 1.0.2 along with some enhancements and bug fixes.

Breaking Changes

• Breaking changes in RxJava. Read the RxJava Release Notes for more information.
• Remove Observable.compose and JavaConversions.toJavaTransformer because Scala has extension methods. It's much nicer than compose.
• Rewrite toMap in an idiomatic Scala way.
  • Add def to[M[_, _], K, V](keySelector: T => K, valueSelector: T => V)(implicit cbf: CanBuildFrom[Nothing, (K, V), M[K, V]]): Observable[M[K, V]].
  • Remove def toMap[K, V] (keySelector: T => K, valueSelector: T => V, mapFactory: () => Map[K, V]): Observable[Map[K, V]].
    In Scala, we can use CanBuildFrom to build a Map instead of mapFactory.
• Rewrite toMultimap in an idiomatic Scala way.
  • Change the return type from Observable[scala.collection.Map[K, Seq[T]]] to Observable[mutable.MultiMap[K, V]].
  • Change the method name toMultimap to toMultiMap to make it consistent to the return type.
  • Remove toMultimap(keySelector, valueSelector, mapFactory, bufferFactory). You can override MultiMap.makeSet to
    create your custom bufferFactory Instead.

See RxScalaDemo.toMapExample
and RxScalaDemo.toMultiMapExample
for examples of new toMap and toMultiMap.

0.21.1

The first release after splitting from RxJava into its own top level project RxScala.

This is the same code as version 0.20.x except:

• all deprecated methods and types are deleted
• now published to groupId io.reactivex instead of com.netflix.rxjava
• artifactId is now rxscala_2.10 and rxscala_2.11 instead of rxjava-scala

io.reactivex:rxscala_2.10:0.21.1
io.reactivex:rxscala_2.11:0.21.1

The artifacts can be found on maven Central at: http://repo1.maven.org/maven2/io/reactivex/rxscala_2.10 and http://repo1.maven.org/maven2/io/reactivex/rxscala_2.11
