note: >-
  ModRetro publishes no API changelog — the commerce API is a UCP/Shopify surface it does not
  version itself. What it does publish, in the open and with dates, is the Chromatic firmware
  changelog: a Keep-a-Changelog-shaped CHANGELOG.md plus tagged GitHub releases carrying the same
  notes, in the GPL-3.0 FPGA design repository. Recorded here as the provider's real dated
  changelog, explicitly scoped to firmware so nobody reads it as API release notes.
