Changelog
Notable changes to the SuperBooks developer platform.
Changes to the public API, the SDKs, and this documentation. Newest first.
Breaking changes to the tool surface are announced here before they ship. Additive changes — new tools, new optional parameters — can land at any time, so write clients that ignore unrecognised response fields.
