Spring Cloud Hoxton.RC2 Released

On behalf of the community, I am pleased to announce that the Release Candidate 2 (RC2) of the Spring Cloud Hoxton Release Train is available today. The release can be found in Spring Milestone repository. You can check out the Hoxton release notes for more information.

Notable Changes in the Hoxton Release Train

Spring Cloud Hoxton.RC2 is built upon Spring Bot 2.2.1.RELEASE.

Spring Cloud Vault

Spring Cloud Circuitbreaker

Spring Cloud Gateway

  • Added a filter which uses the new Spring Cloud CircuitBreaker library to provide circuit breakers to routes

Spring Cloud Config

Spring Cloud Sleuth

Spring Cloud Contract

Spring Cloud Stream

  • Add support to allow a single instance to consume from multiple partitions where non-native partitioning (e.g. RabbitMQ) requires an instance per partition
  • Backpressure Support in Reactive Consumers. Changed channel-to-publisher adapter logic to use EmitterProcessor which effectively transforms the Publisher to a back-pressure honoring one
  • Kafka binder - Provide a custom header mapper that is identical to the DefaultKafkaHeaderMapper in Spring Kafka. This is to address some interoperability issues between Spring Cloud Stream 3.0.x and 2.x apps
  • Kafka Streams binder - health indicator and metrics improvements
  • Rabbit binder - Support provisioning of Quorum queues - Add queue arguments to support provisioning quorum queues
  • Rabbit binder - Multiple partition support. Added support for partitioned multiplex
  • Enhancements in documentation

Spring Cloud Openfeign

Spring Cloud Netflix

  • Added property to disable Spring Cloud CircuitBreaker Hystrix auto-configuration
