 \r
 Possible impacts:\r
        Platforms which uses the default value of PCD (not overriding in DSC) would get updated report status code value for setting virtual address map.\r
+\r
+EDK_9394: Non-Compatible: qhuang8\r
+\r
+       GUID value of EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL_GUID and gEfiFirmwareVolumeBlockProtocolGuid has been changed to \r
+        that of EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL_GUID defined in PI 1.2 spec.\r
+               \r
+\r
+Possible impacts:\r
+       This is a source level compatible change, but not binary level. We might need to rebuild some old binary modules to work with newer version of MdePkg.\r
+\r
+\r
+EDK_9817: Non-Compatible: qhuang8\r
+       Scrub EFI_ATA_IDENTIFY_DATA and EFI_ATAPI_IDENTIFY_DATA to strict follow newest ATA spec (ATA-8). This is a build non-backward compatible changes for ATA-related modules.\r
+       The ATA5_IDENTIFY_DATA in MdePkg\IndustryStandards\Atapi.h is exactly the same as the original ATA_IDENTIFY_DATA for backward compatibility support to follow ATA-5 spec. \r
+\r
+Possible impacts:\r
+       We can fix the build breaks for some renaming issues (e.g. Word 49 in EFI_ATA_IDENTIFY_DATA renamed from "capabilities" to "capabilities_49")\r
+       For the fields that are "obsolete" in newest ATA spec, we can use type-cast to older ATA spec structure (e.g. ATA5_IDENTIFY_DATA). \r
+       (There  should not be any runtime issues if the build issues have got solved in the source correctly.)\r
