  OSHA publishes no web changelog for its APIs. The only dated change history that exists is
  the Changelog section printed inside the ITA API documentation PDF, transcribed verbatim
  below. A second, unrelated changelog covers the DOL developer PORTAL (not the API) and
  stops in 2015; it is recorded at the bottom for completeness.
