current_version: v1.73.0
current_version_date: '2026-09-11'

breaking_change_policy: 'The Buf CLI follows semver within 1.x. The BSR API it talks to is versioned separately
  by Protobuf package: v1 packages are stable and will not break, v1beta1/alpha may. registry-proto enforces
  this in CI with buf breaking WIRE_JSON.'

  it does publish is the Buf CLI release stream on GitHub, which is also what gates access to new BSR
  features. Entries below are the ten most recent releases, classified by the leading verb of each bullet.
