# Changelog (/data-api/changelog)

Release notes and versioning updates for the Fiskil Data API.



All changes to the Data API are listed here. For changes made before the new
versioning model, see the [Legacy Changelog](/data-api/changelog/legacy).

For how version selection works — the `X-Fiskil-Version` header, Console pinning, and what
counts as a breaking change — see [API Versioning](/data-api/guides/core-concepts/versioning).
