Introducing Protobuf Editions - Matt Kulukundis & Mike Kruskal, Google
summary
Protobuf Editions introduces edition-scoped defaults and per-field features that let generated APIs evolve incrementally without changing wire format; features are intended as guaranteed behaviors, not suggestions. A C++ implementation is complete and edition 2023 shipped in 24.0 behind an experimental flag, Objective-C is done, and Java, Python, Ruby, PHP and Go ports are in progress for rollout this year. Tools include a wire decoder (protoscope) and an upgrader (prototeller / protoc-gen-edition under development) that automates safe proto edits.
