I heared rumors that Spring XD lost development drive and focus at Spring shifts towards cloud services. Since I'm considering XD (the otehr one I consider is Apache Beam, though not yet mature enough imho), I'd like to get some facts / release plan for the future of XD instead of relying on rumors.
The Spring XD homepage has an announcement at the bottom of the page:
Announcement
Building upon Spring Boot and Spring Cloud capabilities, Spring XD is actively being redesigned as Spring Cloud Data Flow - a cloud native programming and operating model for composable message-driven microservices. For more information and the reasons behind this redesign, please refer to Spring Cloud Data Flow's launch blog.
Spring XD's 1.3 GA will be the last release in the 1.x line and with this release, 1.x will be officially in maintenance mode, addressing only bug fixes.
