+Remove SafeFreePool from MemoryAllocationLib as this API's name is misleading. Its implementation only check if a pointer is NULL. If a garbage pointer is passed in, the gBS->FreePool will still ASSERT in debug build and return error code. \r
+\r
+It is recommended that module writer should keep track how a pointer is allocated and free it after use.\r

+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
