Overview

This release of the github.com/golang/protobuf module introduces a number of significant changes relative to the previous minor release. In particular, this module is now implemented in terms of the new google.golang.org/protobuf module, which is the next major revision of Go bindings for protocol buffers. From this point onwards, most of the development effort for Go protobufs will be dedicated to the new module, with minimal changes being made to this module.

See the release notes for the new module for specific implementation details that may affect this release.

Backwards compatibility

This release maintains backwards compatibility with previous releases of this module. Any observable changes in behavior are to fix bugs, change unspecified behavior, or to make behavior more compliant with the protobuf specification. The compatibility document provides us the freedom to make changes in these areas.

Notable changes

Wire serialization

Wire serialization is now implemented in terms of the new proto package by calling out to the relevant functionality in that package (e.g., proto.Marshal and proto.Unmarshal). There should be no observable changes in behavior other what is mentioned elsewhere in the release notes (e.g., behavior around errors or nil values).

JSON and text serialization

The JSON and text format implementations have been ported to use protobuf reflection under the hood instead of relying on Go reflection. This provides flexibility as they can operate on any concrete message type that properly implements the new proto.Message interface.

The implementations do not use the new protojson or prototext packages in order to maintain a higher degree of backwards compatibility. Our analysis unfortunately showed us that too many tests rely on their output being stable by performing byte-for-byte comparisons. Even though the compatibility promise gives us the freedom to change the output, we have chosen not to do so for pragmatic reasons. The implementations are now functionally frozen (bugs and all) and will not receive future improvements. Users are encouraged to migrate to the protojson or prototext packages instead.
