Spring Cloud Hoxton RC2 Release

Spring Cloud Hoxton candidate release RC2 is now available. It can be downloaded from the Spring Milestone repository (a private repository is required if not uploaded to the central repository).

Major Changes in the Hoxton Release Series

Spring Cloud Hoxton RC2 is built on Spring Boot 2.2.1.RELEASE. For details on the issues addressed by Spring Boot 2.2.1, refer to the spring-boot/releases page.

Spring Cloud Vault

Upgraded to Spring Vault 2.2 GA (see spring-vault-2-2-goes-ga ).

Upgraded Netty to 4.1.43.Final.

Spring Cloud Circuitbreaker

A new property has been added to disable Resilience4J auto‑configuration:

spring.cloud.circuitbreaker.resilience4j.enabled=false

Spring Cloud Gateway

Supports Spring Cloud CircuitBreaker as a circuit‑breaker abstraction, intended to replace HystrixGatewayFilter.

Spring Cloud Config

By default, encrypted values in plain‑text files are not decrypted. To enable decryption for plain‑text files, set the following properties:

spring.cloud.config.server.encrypt.enabled=true

spring.cloud.config.server.encrypt.plainTextEncrypt=true

Only YAML, JSON, and .properties file extensions support decryption. If this feature is enabled and a request is made for an unsupported file extension, any encrypted values in the file will remain undecrypted.

Spring Cloud OpenFeign

Official support for Spring Cloud LoadBalancer has been added. See the Spring Cloud LoadBalancer documentation for details.

Spring Cloud Netflix

A property has been added to disable the auto‑configuration of Spring Cloud CircuitBreaker Hystrix:

spring.cloud.circuitbreaker.hystrix.enabled=false
