v4.1.1

⚠️ Attention Required

  • Spring Boot's Gradle plugin no longer automatically configures gRPC when the Protobuf plugin is applied. This behavior caused problems for those using Protobuf without gRPC. To opt in to the configuration of gRPC, configure the protobuf extension with the grpc plugin using an empty block. The Spring Boot Gradle plugin will then automatically configure the use of protoc-gen-grpc-java as before. #50822
