On behalf of the community, I am pleased to announce that the Milestone 2 (M2) of the Spring Cloud 2023.0 Release Train is available today. The release can be found in Spring Milestone repository. You can check out the 2023.0 release notes for more information.

Notable Changes in the 2023.0.0-M2 Release Train

In this milestone, we have migrated the documentation of all the Spring Cloud projects to Antora.

See all issues and pull requests here.

Spring Cloud Commons

  • Refresh Scope on restart - a feature tailored to allow adapting to environment changes on JVM Checkpoint-Restart (PR 1266)

Spring Cloud Gateway

  • Specify clientRegistrationId in TokenRelay filter. (PR 2922) The gateway can be used to manage many ClientRegistrations, and each route can determine which client registration to use. This is incredibly useful in scenarios where there are (for example):
    • multiple authorization servers in use simultaneously.
    • multiple client authentication methods in use simultaneously.
    • some/all downstream services require a distinct clientId, aud claim, etc.
    • some/all downstream services require different token formats (e.g. JWT, opaque)

Spring Cloud OpenFeign

  • Upgraded to Feign 12.5 (PR_907)

Spring Cloud Task

  • Users now have the ability to query for task executions using the external execution id. (PR_863)

Spring Cloud Function

Spring Cloud Stream
