  Dated release history for Oracle REST Data Services, the component that publishes the OpenAPI
  contract in this repo. Oracle publishes no changelog for the Partitioning option itself — a
  database option changes with the Oracle Database release it ships in, and those changes are
  documented in the VLDB and Partitioning Guide per database version rather than as a dated feed.
