+       Remove the macro value TIME_OUT defined in MdePkg/Include/Uefi/UefiUsbLib.h and replace it with a new PCD entry:\r

+       \r
+Possible impacts:\r
+       All modules depending on macro TIME_OUT in MdePkg/Include/Uefi/UefiUsbLib.h should use PcdGet32 (PcdUsbTransferTimeoutValue)\r

+       2 default values of status code PCDs updated in MdePkg.dec.\r
+\r
+       1) PcdStatusCodeValueBootServiceExit. Its value is changed from 0x3100019 to 0x3101019, which equals EFI_SOFTWARE_EFI_BOOT_SERVICE | EFI_SW_BS_PC_EXIT_BOOT_SERVICES.\r

+Possible impacts:\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

+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
