Protobuf Editions are here: don't panic
Most Protobuf users should ignore Editions and continue using proto3. If you become an early adopter, we’ve been working closely with Google to ensure that Buf will support editions as soon as they’re generally available.
This introduces an alternative approach to syntax-based schema semantics choices and relies more heavily on finer-grained file, message, or field-level options to opt into or out of Protobuf language features on a case-by-case basis. It should be a boring change that gives plugin maintainers finer-grained control over how future versions of their Protobuf runtimes behave, improvements are made, and new features are introduced. As the ecosystem learns more about how these new capabilities meld with existing enterprise codebases and deployments, we'll continuously codify our recommendations and best practices into our linter and breaking change detection tooling to support you.
