summary: >-
  Upland maintains a Release Notes section in its developer documentation with eight dated entries.
  Entries are titled by month and day only — no year is printed on any of them and no publication
  date is exposed in the page metadata — so `date` is recorded as null and the label is preserved
  verbatim rather than a year being inferred.
scheme: dated release notes, no semantic version tags
current_version: 1.0.0
current_version_source: info.version in openapi/upland-developers-api-openapi.json

  The GitBook docs embed a spec file named developers-api-v.1.0.6.json whose own info.version is
  also 1.0.0. The 1.0.6 in the filename is not reflected anywhere machine-readable.
