On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.8.0 has been released and is now available from Maven Central. This is the first "non-experimental" release, signified by the project moving to its new repository location in the https://github.com/spring-projects organization. Support will be provided for the only current 0.x release, and the normal cycle of extended support will start with the 1.0.0 release (expected around the same time as Spring Boot 4.0.0).
The main change in this release was to upgrade Spring Boot and also the gRPC Java and Protobuf libraries. Protobuf is now at version 4.
