Dear hakkers, we—the Akka committers—are proud to announce the THIRD RELEASE CANDIDATE for the upcoming release of Akka 2.4.2. The main change in the upcoming Akka 2.4.2 release is that it includes Streams & HTTP, with the akka-stream, akka-stream-testkit, akka-parsing, and akka-http-core modules no longer being marked “experimental” (i.e. the -experimental suffix has been removed from these artifact names while it remains on the others, most notable akka-http-experimental_2.11). In comparison to Streams & HTTP 2.0 the main changes are:
significant performance improvement for HTTP handling, now reaching roughly 75% of Spray’s performance—this is not the end of the performance work, we have only just begun replacement of all uses of the Unit type (represented as BoxedUnit in Java) with the more descriptive types akka.Done (for signaling successful completion) and akka.NotUsed (for materialization results of stages that do not produce a value) usage of Java 8 types in the Java DSLs: java.util.Optional instead of scala.Option and java.util.concurrent.CompletionStage instead of scala.concurrent.Future Especially the second and third point mean that porting code from Streams & HTTP 2.0.x to Akka 2.4.2 will require some mechanical source code changes, please refer to the migration guide (for Java <http://doc.akka.io/docs/akka/2.4.2-RC3/java/stream/migration-guide-2.0-2.4-java.html> or Scala <http://doc.akka.io/docs/akka/2.4.2-RC3/scala/stream/migration-guide-2.0-2.4-scala.html>) for the details. All changes since 2.4.2-RC2 can be found here <https://github.com/akka/akka/compare/v2.4.2-RC2...v2.4.2-RC3>. For the list of open tickets (mostly documentation) remaining for 2.4.2 please refer to the github milestone <https://github.com/akka/akka/milestones/2.4.2>. We intend to release version 2.4.2 as soon as we are confident that it is reasonably bug free and the documentation is top notch as well: we are aware that the getting started experience for Streams & HTTP is not perfect in places and there are some features that are entirely missing—stay tuned for updates and please let us know of anything you find to be suboptimal.
