Release Notes

v1.29.0

Compare Source

• Add support for yaml format. All commands that take image inputs, output images,
  or convert between message formats, now take yaml as a format, in addition to
  the existing binpb and txtpb formats. Some examples:
  • buf build -o image.yaml
  • buf ls-files image.yaml
  • buf convert --type foo.Bar --from input.binpb --to output.yaml
• The yaml and json formats now accept two new options: use_proto_names and
  use_enum_numbers. This affects output serialization. Some examples:
  • buf convert --type foo.Bar --from input.binpb --to output.yaml#use_proto_names=true
  • buf convert --type foo.Bar --from input.binpb --to -#format=yaml,use_enum_numbers=true
• Fix issue where buf format would inadvertently mangle files that used
  the expanded Any syntax
  in option values.
