+Possible Impacts:\r
+        Every change listed above is non-backward compatible for MdePkg and other packages. It is required to update module\r
+        sources (*.c;*.h), module meta data files (*.inf) and update the platform DSC files to fix the build break.\r
+        However, it is less likely to bring about functional issue for these updates.\r

+Possible Impacts:\r
+       Modules depending on UefiScsiLib for these macros should update the source to use new UefiLib macros\r
