Reactive Streams is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure.
Four months have passed since Reactive Streams 1.0.1 was released, and back then it was promised that after JDK9 had shipped, a compatibility/conversion library—to seamlessly convert between java.util.concurrent.Flow.* and the org.reactivestreams namespaces—would be coming in the next release.
Not only have we done that in 1.0.2—a TCK for implementations of the java.util.concurrent.Flow interfaces is also included in this release, so no more need to manually adapt your java.util.concurrent.Flow.* implementations to the Reactive Streams namespace in order to use the TCK anymore!
As all other 1.0.x releases of Reactive Streams, 1.0.2 is binary—and semantically—compatible with the previous releases. Also, all artifacts, documentation, and the specification is licensed under Creative Commons Zero (Public Domain).
Some of the highlights of the 1.0.2 release are: the Flow adapters, the Flow TCK, Automatic-Module-Names in all of the artifacts, improved TCK coverage, the RangePublisher example, and specification clarifications.
Akka Streams has already merged support and passed all TCK tests for Reactive Streams 1.0.2, and will release it shortly, in the upcoming Akka 2.5.9 release.
