+Summary of changes to \PEP 571
+==============================
+
+The following changes were made to this PEP based on feedback received after
+it was approved:
+
+* The maximum version symbol of ``libgcc_s`` was updated from ``GCC_4.3.0``
+  to ``GCC_4.5.0`` to address 32-bit Cent OS 6. This doesn't affect x86_64
+  because ``libgcc_s`` for x86_64 has no additional symbol from
+  ``GCC_4.3.0`` to ``GCC_4.5.0``.
