# File attachments in chat, Notion-style blog editor and deployment tracking

*Version 1.222 – released 2026-02-09*

## File attachments in chat

Merchants and customers can attach files to chat messages – images, PDFs, documents (YNS-919). Attachments are scoped to the conversation and respect the store's retention policy.

## Notion-style blog editor

The admin blog editor switches to a block-based UI with slash commands, drag-to-reorder blocks, and inline embeds. Companion blog management API endpoints also land in this release.

## Deployment tracking

Elliot now shows real-time deployment status inline with the chat – building, deploying, promoted, or failed – powered by Vercel Platform Elements. Includes one-click promote to production and an option to prevent automatic production deployments.
