Spring Cloud 2020.0 GA Released: What's New and How to Upgrade?

Release Overview

On December 22, 2020, Spring Cloud 2020.0 GA was released. It aligns with Spring Boot 2.4.1 (not 2.4.0 due to configuration bugs).

Key Changes

Spring Cloud Commons : Bootstrap is disabled by default; configuration import now uses Spring Boot 2.4's spring.config.import with decryption support. To retain the old bootstrap, add the org.springframework.cloud:spring-cloud-starter-bootstrap dependency.

Spring Cloud LoadBalancer : Added server‑side statistics support.

Spring Cloud Security : Module removed and its code moved to the Spring Cloud Common module.

Spring Cloud OpenFeign : Added adaptation for Spring Cloud CircuitBreakers and support for LoadBalancer statistics.

Spring Cloud Gateway : Added LoadBalancer statistics support.

Spring Cloud Task : Added documentation for single‑step batch jobs.

Spring Cloud Kubernetes : Kubernetes client code moved to the spring-cloud-kubernetes-commons module.

Spring Cloud Netflix : Deprecated modules removed, including archaius, hystrix, ribbon, zuul, and related starters.
