  Thanx runs TWO change surfaces and neither is an API changelog. docs.thanx.com/data/changelog
  is a dated changelog scoped to DATA EXPORT SCHEMA changes, and it carries the platform's only
  written compatibility contract (additive-only columns, retired columns emptied rather than
  dropped). thanx.launchnotes.io is a product-release feed for the merchant-facing product,
  organized by category and subscribable, with a public roadmap section. The REST APIs
  themselves have no dated changelog: version changes are announced to partners directly and
  the client pins with Accept-Version: v4.0.
