Hi / Bonjour friends 👋

This month we invite you to test the **Beta** for the newest version of Carbone: **v4.0.0**. 🎉
After carefully listening to your feedback, we made Carbone more powerful than ever (and that's only the beginning). As always, we value future-proof and sustainability, the version is fully backward compatible with all of your templates. 

## What's new ?

* 📊 Dynamic charts for ODT and DOCX templates. Charts can be created natively from your text editor, or by inserting advance beautiful charts with [echarts](https://echarts.apache.org/examples/en/index.html) as images. **(Enterprise Edition Only)**
* ⚡️ Aggregator formatters for arrays:  `aggSum`, `aggAvg`, `aggMin`, `aggMax`, `aggCount` ! You don't have to pre-compute values anymore :D **(Enterprise Edition Only)**
* 🚩 Improved Syntax Errors
* 🦄 Bugs fixed

Usage examples and details are available on the [changelog](https://links.support.carbone.io/file/upload/operator/9e42f7a866c59800/v400-beta_h9yk5u.pdf).

**Enterprise Edition Services**: Carbone Render API, Carbone Studio or Carbone On-premise

## Access

The beta is available only through the Carbone Render API. When requesting the API, add the header `"carbone-version":"4-beta"`.
Don't use the Beta into your production environment.
