Helidon reactive programming library has been based on Java Flow API since version 2.0.0, June 2020. So not really the first... |

@tomas-langer But the usage documentation of helidon reactive is poor |

We are now working on documentation with highest priority. So with the new release of Helidon (coming quite soon) the documentation is going to be vastly extended and much better structured! |

Mutiny is well on its way towards version 2.0.
Be assured that as a user of Mutiny you won’t have to worry much about upgrading your code from
1.xto2.0. We are taking binary compatibility very seriously, and each Mutiny release comes with a list of justifications and migration tips for breaking changes if any.So far the main justification for moving to 2.0 has been the transition from Java 8 to Java 11 as a baseline. This is a proper breaking change in semantic versioning parlance, hence the shift of the major version.
But today we are proud to announce that we will make another move towards modern Java by being the first major reactive programming library dropping the dependency on the legacy Reactive Streams APIs, and transitioning to Java Flow (see java.util.concurrent.Flow).
Java Flow was introduced in Java 9 (already a long time ago!) and is isomorphic to the original Reactive Streams APIs. The Reactive Streams TCK (which verifies the correctness of the implementations) ships with a Java Flow variant. The Mutiny Zero project offers adapters between Java Flow and the legacy Reactive Streams APIs, so you will never be locked out as the Java reactive ecosystem should be transitioning towards modern Java.
