Notable changes

New Features
Protobuf editions are fully supported. You can now use edition = "2023" in .proto files together with the proto-gen-go. Edition2023 does not introduce any new features but can be used to replace syntax "proto2/3". Future editions might introduce new features. See https://protobuf.dev/editions/overview/ for more details on protobuf editions.
