 - Introduce the `use_class_methods` strategy. Learn more [here](https://catt.rs/en/latest/strategies.html#using-class-specific-structure-and-unstructure-methods).

-- Implement the _union passthrough_ strategy, enabling much richer union handling for preconfigured converters. [Learn more here](https://catt.rs/en/stable/strategies.html#union-passthrough).
+- Implement the `union passthrough` strategy, enabling much richer union handling for preconfigured converters. [Learn more here](https://catt.rs/en/stable/strategies.html#union-passthrough).
 - The `omit` parameter of {py:func}`cattrs.override` is now of type `bool | None` (from `bool`).
   `None` is the new default and means to apply default _cattrs_ handling to the attribute, which is to omit the attribute if it's marked as `init=False`, and keep it otherwise.
 - Fix {py:func}`format_exception() <cattrs.v.format_exception>` parameter working for recursive calls to {py:func}`transform_error <cattrs.transform_error>`.
