+## 25.2.0 (unreleased)
+
+- Add a `use_alias` parameter to {class}`cattrs.Converter`. 
+  {func}`cattrs.gen.make_dict_unstructure_fn_from_attrs`, {func}`cattrs.gen.make_dict_unstructure_fn`,
+  {func}`cattrs.gen.make_dict_structure_fn_from_attrs`, {func}`cattrs.gen.make_dict_structure_fn`
+  and {func}`cattrs.gen.typeddicts.make_dict_structure_fn` will use the value for the `use_alias` parameter from the given converter by default now.
+  If you're using these functions directly, the old behavior can be restored by passing in the desired value directly.

 ## 25.1.1 (2025-06-04)
 
 - Fixed `AttributeError: no attribute '__parameters__'` while structuring attrs classes that inherit from parametrized generic aliases from `collections.abc`.
