API Change Log

This changelog contains the versions and dates of changes to the Naurt Final Destination API.

Naurt uses SemVer versioning with the addition of “-hf.x” for bug fixes of the same version. When a new major version is released, Naurt creates a new endpoint (e.g. final-destination/v2), and maintains support for the old version to ensure compatibility.
