## API version: v2023-01-05

### Cross-API

* 💥 🔒 **Format and access control of File URLs**: All API responses now serialize file URLs differently. Each file URL now contains a signed access token, which remains valid for 6 hours after the API request was made. For details, see [File URLs](/downloading-files).

### Graph

*As of 2023-01-05, Graph is in closed beta. To learn more and request early access, see the [Graph product page](https://withpersona.com/product/graph).*

* 💥 **Format of Graph Query responses**: Graph Query responses now show computed stats for the query results instead of the raw result output.
