Notable Changes in the Hoxton Release Train
Github project.
Hoxton.SR5 is compatible with both Spring Boot 2.3.x and 2.2.x. Previous Hoxton releases are only compatible with Spring Boot 2.2.x.
Spring Cloud CLI was not released as part of Hoxton.SR5, look for a release with Hoxton.SR6.
Spring Cloud Contract
Support was added for Spring Cloud LoadBalancer.
Please see release notes for information on upgrades and a minor API change in the Spring Cloud Contract Gradle Plugin.
Spring Cloud Kubernetes
Labels were added to the health endpoint.
Spring Cloud Commons
Builders were added to configure Spring Cloud LoadBalancer as well as pre-configured loadBalancers. LoadBalancer caching mechanism was adjusted to support HealthCheckInstanceListSupplier.  Support was added for non-enumerable property sources. Support was added for a cached random property source so service instance ids with random values will not be redefined during a refresh event.
Please see release notes for information on changes in two property value defaults.
Spring Cloud Netflix
Eureka Client now uses the Eureka HTTP API during bootstrap so that instances are not registered then deregistered.
Spring Cloud Consul
Support was added for Consul metadata rather than metadata in tags.
Spring Cloud Config
Updated support for Vault Azure MSI authentication.
Spring Cloud Gateway
Added support for custom Host headers.
Spring Cloud Zookeeper
Added a CuratorFrameworkCustomizer to allow users to customize Curator after auto-configuration.
Spring Cloud Bus
@RemoteApplicationEventsScan results are now cumulative. RefreshRemoteApplicationEvent is only processed locally if targeted.
Spring Cloud Openfeign
Support was added for sorting Spring Data pagination. Support was added to disable parent context of individual feign clients. An ErrorDecoderFactory was added.
Spring Cloud Sleuth
The ExceptionLoggingFilter was disabled by default.
