# v3.3.1 — May 2026

> Category field and cleaned image flag

* Added `category` field to [`GET /v1/products/{product_id}`](/api-reference/v1/product-detail) and [`POST /v1/lookup`](/api-reference/v1/lookup-product) responses — includes the product's category slug and title
* Added `is_cleaned_image` flag to product image models — `true` when the image has a square aspect ratio and uniform background, ideal for product grids
