# Blog comments, refunds API and agent browser in sandbox

*Version 1.240 – released 2026-04-02*

## Blog comments and categories

Blog posts now accept comments with a moderation queue, comment categories, and spam controls. Posts can also be grouped into categories, with matching API endpoints for listing and filtering.

## Refunds API

REST endpoints for listing, creating, and retrieving refunds, with a matching admin UI for managing them. Refund events trigger a customer-facing confirmation email with the expected arrival window.

## Agent browser in sandbox

Elliot's sandbox now ships with `agent-browser` – a headless browser the agent drives itself to verify changes in a real rendered page, instead of trusting static output.

## Also shipped
- **Cart recommendations commerce tool** – a new commerce tool Elliot can call to surface upsells and cross-sells based on current cart contents
- **Shopify product migration in Elliot** – import products from Shopify (and similar platforms) directly inside the Builder
