Introducing Java Functions for Spring Cloud Stream Applications - Part 0

We are happy to announce the release of Spring Cloud Stream applications 2020.0.0-M2. This release is a complete overhaul of the legacy Spring Cloud Stream App Starters. Starting with this release, we are moving away from theme-oriented release train names (famous scientists in alphabetical order) to calendar based versioning. The current GA release is called Einstein, and we are pleased to introduce 2020.0.0-M2. We are also moving away from the app starters. Having reorganized, repackaged, and (in some cases) rewritten the underlying code, we now have a new Git repository: spring-cloud/stream-applications: Functions and Spring Cloud Stream Applications for data driven microservices.

Earlier this month, we released a first milestone of Reactor 2020.0.
This cycle, codename Europium, follows the Dysprosium one (which included reactor-core 3.3.x and reactor-netty 0.9.x).

It includes reactor-core 3.4.0 and reactor-netty 1.0.0.

In this blog post, we’ll cover a few highlights of the reactor-core milestone, and briefly mention what’s in store for M2.

For reactor-netty, we’ll link to a separate blog post here as soon as it is out.

Note also that there is a new versioning scheme in place, which has been adopted accross the Spring portfolio: see the reference guide and this blog post.

Over time the use of patterns in web applications grew in number and syntax with AntPathMatcher evolving to meet those needs but some pain points remain without a solution:
