VMware has released Spring Cloud 2022.0.0, codenamed Kilburn, which includes updates to many Spring Cloud subprojects. Spring Cloud is based on Spring Framework 6 and Spring Boot 3, which were introduced in November 2022, and is compatible with Java 17 and Jakarta EE 9. GraalVM supports Ahead of Time (AOT) compilation and the creation of native images.
By configuring spring.cloud.loadbalancer.configurations as weighted, Spring Cloud Commons supports weighted load-balancing. Spring Security now supports OAuth2 as part of its OAuth integration.
As a replacement for Spring Cloud Sleuth, Spring Cloud Gateway now supports Micrometer for observability. The property CORS may be disabled
Spring Cloud Kubernetes now supports fabric8 6.2.0 and Kubernetes Java Client version 17. The Kubernetes-specific annotation, @ConditionalOnKubernetesEnabled, has been replaced with the more generic @ConditionalOnCloudPlatform Spring Boot annotation. Secrets and configmaps based on names and labels are now read separately to avoid potential issues. With the DiscoveryClient, service discovery can now be filtered by namespace to prevent exceptions when trying to access restricted namespaces.
Spring Cloud Contract does not support Pact out of the box, since Pact, a tool for contract testing, broke binary and functional compatibility, even with patch versions. You may use the migration guide to upgrade existing applications to the latest version of Spring Cloud Contract.
Spring Cloud OpenFeign has been declared feature complete, which means that no new features will be added, but security issues and bugs will be addressed, and minor pull requests from the community will be considered. Version 6.0 of the Spring Framework introduced the HTTP Interface, which will replace OpenFeign.
The Spring Cloud CLI, Spring Cloud Cloudfoundry, and Spring Cloud Sleuth have been removed from the release train.
