 ## 2.6
 
+-   **NEW**: Add official support for Python 3.13.
 -   **NEW**: Add support for `&` as scoping root per the CSS Nesting Module, Level 1. When `&` is used outside the
     context of nesting, it is treated as the scoping root (equivalent to `:scope`).
 -   **FIX**: Improve error message when an unrecognized pseudo-class is used.
