gRPC Support Moves Into Spring Boot 4.1 With New Starters

Spring Boot 4.1 GA, released June 10, 2026, now includes native gRPC starters under org.springframework.boot, replacing the deprecated spring-grpc artifacts. Property names have changed, such as spring.grpc.client.channels to spring.grpc.client.channel and address to target. The build configuration is simplified: dropping a .proto file into src/main/proto/ auto-generates code with no manual protobuf setup.
