Spring Cloud Hoxton.RC2 Released

November 12, 2019

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

Issues

Spring Cloud Circuitbreaker

Added property to disable Resilience4J auto-configuration

Spring Cloud Gateway

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

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

Support for Spring Cloud LoadBalancer has been added
Issues

Spring Cloud Netflix

Added property to disable Spring Cloud CircuitBreaker Hystrix auto-configuration
