> [!IMPORTANT]
> **This is the `main` branch which contains v2 of the SDK (currently in development, pre-alpha).**
>
> We anticipate a stable v2 release in Q1 2026. Until then, **v1.x remains the recommended version** for production use. v1.x will continue to receive bug fixes and security updates for at least 6 months after v2 ships to give people time to upgrade.
>
> For v1 documentation and code, see the [`v1.x` branch](https://github.com/modelcontextprotocol/python-sdk/tree/v1.x).
