# Release notes

For a detailed list of all changes, see the [Changelog](./changelog).
For details about versioning, see our [Versioning Policy](https://docs.activeviam.com/atoti-eos.html).

## 6.2.0

2026/07/27

### New Features

* The Atoti chat now uses dynamic tool discovery. Instead of sending every available tool with each request, the model searches a keyword index for matches. This reduces token usage and improves tool selection.
* The Atoti Java SDK now includes a `Dimension` API to control which cube attributes are exposed to the AI tools.
* Auto-Explain, which identifies the root causes behind measure variations, now has a Python API in the Atoti Python SDK. See [How to set up Auto-Explain in Python](../developer-guide/enable-ai-tools/auto-explain/setup-python).
* The Atoti Python SDK now offers `Session.chat` to start a chat session against a cube.
* The Atoti Python SDK now exposes the `AiConfig.disclaimer` attribute, letting the disclaimer shown with AI responses be customized. See [How to set up a custom disclaimer in Python](../developer-guide/enable-ai-tools/disclaimer/setup-python).

### Improvements

* The chat system prompt was improved to help the LLM navigate the UI.
* Fixed the Atoti MCP Server credentials page, which failed to load when the application ran under a custom context path.
