Spring Cloud Greenwich.RELEASE is now available

Releases | Ryan Baxter | January 23, 2019 | ...

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

End of Life (EOL) Reminder

The Edgware release train will reach EOL status on August 1st, 2019. You can read the formal announcement here.

The Spring Cloud Finchley release train is considered a major release and is tied to the Spring Boot 2.0.x release. Therefore, the Spring Cloud Finchley release train will reach EOL status when the Spring Boot 2.0.x release branch is marked EOL. An announcement about this will be made on this blog once a date has been determined.

The Spring Cloud Greenwich release train is considered a minor release and will continue support for the Spring Boot 2.x release branch.

Notable Changes in the Greenwich Release Train

Updates were made across all projects for Java 11 compatibility.

New Projects

There are two new projects included in the Greenwich Release train, Spring Cloud GCP (which provides integration with Google Cloud Platform), and Spring Cloud Kubernetes (which provides integration with Kubernetes).

Spring Cloud Netflix Projects Entering Maintenance Mode

Recently, Netflix announced that Hystrix is entering maintenance mode. Ribbon has been in a similar state since 2016. Although Hystrix and Ribbon are now in maintenance mode, they are still deployed at scale at Netflix.

The Hystrix Dashboard and Turbine have been superseded by Atlas. The last commits to these project are two years and four years ago respectively. Zuul 1 and Archaius 1 have both been superseded by later versions that are not backward compatible.

The following Spring Cloud Netflix modules and corresponding starters will be placed into maintenance mode:

  1. spring-cloud-netflix-archaius
  2. spring-cloud-netflix-hystrix-contract
  3. spring-cloud-netflix-hystrix-dashboard
  4. spring-cloud-netflix-hystrix-stream
  5. spring-cloud-netflix-hystrix
  6. spring-cloud-netflix-ribbon
  7. spring-cloud-netflix-turbine-stream
  8. spring-cloud-netflix-turbine
  9. spring-cloud-netflix-zuul

This does not include the Eureka or concurrency-limits modules.

What is Maintenance Mode?

Placing a module in maintenance mode means that the Spring Cloud team will no longer add new features to the module. We will fix blocker bugs and security issues, and we will also consider and review small pull requests from the community.

We intend to continue to support these modules for a period of at least a year from the general availability of the Greenwich release train.


We recommend the following as replacements for the functionality provided by these modules.

Current Replacement
Hystrix Resilience4j
Hystrix Dashboard / Turbine Micrometer + Monitoring System
Ribbon Spring Cloud Loadbalancer
Zuul 1 Spring Cloud Gateway
Archaius 1 Spring Boot external config + Spring Cloud Config

Look for a future blog post on Spring Cloud Loadbalancer and integration with a new Netflix project Concurrency Limits.
