# Chat widget changelog

> Notable changes to the Circuit chat widget and its API, newest first.

Changes that could affect an existing installation are recorded here. The launcher URL is stable and assets update automatically. You do not need to change your script tag to receive updates.

## July 2026

**General availability of the launcher and iframe embed.** The embed widget is now the supported way to add Circuit chat to your website. Paste a single `<script>` tag from the agent's Chatbot settings page. The launcher (\~2 KB) fetches branding from the new `GET /chat-bot/config` endpoint and renders a bubble; clicking the bubble opens the chat SPA in an iframe. All configuration is managed in the Circuit admin UI and requires no script-tag changes to update.
