On behalf of the community, I am pleased to announce that the General Availability (RELEASE) of the Spring Cloud Finchley Release Train is available today. The release can be found in Maven Central. You can check out the Finchley release notes for more information.

Lifecycle Announcements for Release Train Versions

The Camden release train has reached end-of-life status. The Dalston release train will reach end-of-life status in December 2018. The Edgware release train will follow the end-of-life cycle of the Spring Boot 1.5.x line.

Notable Changes in the Finchley Release Train

Spring Cloud Function and Spring Cloud Gateway are new additions to the Spring Cloud portfolio. The portfolio was also made compatible with Spring Boot 2.0.x which was a significant effort. Spring Cloud now has a minimum version of Java 8.

Spring Cloud Gateway

Spring Cloud Gateway is an API Gateway built on top of Spring Webflux and Reactor Netty. It is a next generation gateway and can be viewed as a replacement for Spring Cloud Netflix Zuul. It provides dynamic routing based on easy to define predicates. It also provides filters that are scoped to each route, examples include: path rewriting, circuit breaker, adding or removing headers, rate limiting and security. Routes can be defined using properties or using included support for DiscoveryClient (Eureka, Consul & Zookeeper).

Spring Cloud Function

Spring Cloud Function is a project with the following high-level goals:

  • Promote the implementation of business logic via functions.
  • Decouple the development lifecycle of business logic from any specific runtime target so that the same code can run as a web endpoint, a stream processor, or a task.
  • Support a uniform programming model across serverless providers, as well as the ability to run standalone (locally or in a PaaS).
  • Enable Spring Boot features (auto-configuration, dependency injection, metrics) on serverless providers.

Spring Cloud Sleuth

  • Removed the sleuth-stream #555 and zipkin-stream #727 dependencies. Spans via messaging can be only sent to Zipkin via native Zipkin dependencies.
  • spring.zipkin.sender.type=kafka needs to explicitly be set to send spans over Kafka #985, #1013
  • Added WebClient.Builder support #779
