   is a replacement for a template type parameter (previously reported a ``CXType_Unexposed``).
 - Introduced the new function ``clang_Type_getReplacementType`` which gets the type replacing
   the template type parameter when type kind is ``CXType_SubstTemplateTypeParm``.
+- Introduced the new function ``clang_Type_getFullyQualifiedName``, which gets the fully
+  qualified name of the given type, including qualification of all template parameters.
