Reactive Streams 1.0.4 is here!

We—the Reactive Streams Special Interest Group—are happy to announce the immediate availability of Reactive Streams version 1.0.4.

In 1.0.4 we have re-licensed under MIT No Attribution (SPDX: MIT-0), improved the TCK, clarified different aspects of the specification, and proved that the Reactive Streams specification is robust and is successfully used by many various implementations.

As usual, 1.0.4 is binary, and semantically, compatible with the previous 1.0.x releases of Reactive Streams.
