# New fields on Shopify Function APIs

New fields have been added to all Shopify Functions APIs.

* The `sellingPlanAllocation` field is now available on `CartLine`.
* The `title` field is now available on `Product`, `CustomProduct`, and `ProductVariant`.
* The `inCollections` field on `Product` allows for checking membership in individual product collections.
* The `hasTags` field on `Product` and `Customer` allows for checking the presence of individual tags.
* The `isAuthenticated` field on `BuyerIdentity` identifies whether the customer is logged in.

For details on these fields, see the [API Reference documentation](https://shopify.dev/docs/api/functions) for Shopify Functions.
