  Cloud Native Buildpacks publishes no single prose changelog. Change is announced through dated
  GitHub Releases on four independent tracks — the specification repo (which cuts one release per
  API version), and the pack, lifecycle and kpack implementations. The spec track is the one that
  represents a contract change for integrators.
scheme: major.minor per API, cut as a tagged GitHub Release
current:
  buildpack_api: '0.12'
  platform_api: '0.15'
  distribution_api: '0.3'
  pack_cli: v0.40.9
  lifecycle: v0.21.18
  kpack: v0.18.0
tracks:
- name: Specification
  url: https://github.com/buildpacks/spec/releases
  cadence: irregular; driven by milestone completion and a super-majority core-team vote
- name: pack CLI
  url: https://github.com/buildpacks/pack/releases
- name: lifecycle
  url: https://github.com/buildpacks/lifecycle/releases
- name: kpack
  url: https://github.com/buildpacks-community/kpack/releases
entries:
- version: platform/0.15
  date: '2025-12-11'
  track: Specification
  title: Platform API 0.15
  breaking: unknown
  note: >-
    Platform API remains on major 0, so the spec's own additive-only guarantee for minor increments
    does not yet apply. Read the release notes before upgrading a platform.

gaps:
- >-
  No aggregate project changelog and no RSS/Atom feed of releases is advertised on buildpacks.io.
  An integrator has to watch four repositories independently.
- >-
  GitHub release notes for the spec tracks do not carry a machine-readable breaking-vs-additive flag;
  the Deprecations sections in buildpack.md and platform.md are the authoritative record.
