+Release type: patch
+
+This release fixes the following deprecation warning:
+
+```
+Failing to pass a value to the 'type_params' parameter of 'typing._eval_type' is deprecated,
+as it leads to incorrect behaviour when calling typing._eval_type on a stringified annotation
+that references a PEP 695 type parameter. It will be disallowed in Python 3.15.
+```
+
+This was only trigger in Python 3.13 and above.
