title: API Release Notes
note: >-
  Lengow maintains a dated, categorised API release-note section inside its API documentation rather than
  a separate changelog site. Each entry names a category of change, the impacted API, the release date
  and a description. The published categories are: New feature, Structure change, Data change,
  Deprecation (functionality that will be deprecated) and Removal (functionality that will be removed
  soon) — so breaking-vs-additive intent is stated. Entries are grouped into "Current Release" and
  "Released". Dates are month-precision for recent entries and day-precision for older ones. Recent
  window captured below; the live page is the source of truth.
scheme: dated release notes, categorised by change type, per impacted API
current_version: v3.0 (orders/marketplaces/documents/reports); v1.0 catalogues API in BETA
