# What's new

Notable new features and improvements in Chat Thing, newest first. This page lists the changes most likely to matter to you, not every fix and small improvement.

## September 2026

- **Book meetings with Cal.com.** Visitors can pick a time and book a meeting without leaving the chat. [Book meetings with Cal.com](https://chatthing.ai/docs/power-ups/book-meetings-cal-com)

- **Choose the voice for spoken answers.** Pick from a range of voices, and preview them, when your web chat reads answers aloud. [Website](https://chatthing.ai/docs/channels/website)

## August 2026

- **Link behaviour setting.** Choose whether links in your bot's answers open in a new tab or in the page the chat is embedded in. [Website](https://chatthing.ai/docs/channels/website)
