On behalf of the community, I am pleased to announce that the Service Release 3 (SR3) 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. All issues closed in this release across all projects can be found in the Spring Cloud Greenwich.SR3 project on GitHub

Notable Changes in the Greenwich Release Train

New Load Balancer Implementations

Spring Cloud Greenwich.M3 is the first release containing both blocking and non-blocking load balancer client implementations as an alternative to Netflix Ribbon which has entered maintenance mode.

To use the new BlockingLoadBalancerClient with a RestTemplate you will need to include org.springframework.cloud:spring-cloud-loadbalancer on your application’s classpath. The same dependency can be used in a reactive application when using @LoadBalanced WebClient.Builder - the only difference is that Spring Cloud will auto-configure a ReactorLoadBalancerExchangeFilterFunction instance. See the documentation for additional information. The new ReactorLoadBalancerExchangeFilterFunction can also be autowired and passed directly to WebClient.Builder (see the documentation). For all these features, Project Reactor-based RoundRobinLoadBalancer is used underneath.
