 - Clang no longer considers the loss of ``__unaligned`` qualifier from objects as
   an invalid conversion during method function overload resolution.
+- Clang now properly handles out of line template specializations when there is
+  a non-template inner-class between the function and the class template
+  (`#65810 <https://github.com/llvm/llvm-project/issues/65810>`_).
