+    1. Clean up device path protocol header file, move device path utility macros to MdePkg\Include\DevicePathLib.h.
+    2. I remove "Efi" prefix for this utility function macro name. 
+    3. The upacked device path type is removed. Should use device path utility macro to access structure's member.
+
+Possible Impacts:
+    1. Customer's module that access device path node's structure need use DevicePathLib
+    2. Should not use unpacked type device path node, this type is retired.
+    3. If want to access private member in device path node, customer module need DuplicateDevicePath() at first to 
+       make sure node is in alignment.

 Possible Impacts:
 	All source codes that refer to EFI_KEY_OPTION.KeyOptions
 	must be changed to use EFI_KEY_OPTION.KeyData from UEFI specification.	
+
+EDK_7057:  Non-Compatible: qhuang8
+	Retired the following macros defined in MdePkg/Include/Uefi/UefiBaseType.h:
+	EFI_SIGNATURE_16, EFI_SIGNATURE_32, EFI_SIGNATURE_64, EFI_FIELD_OFFSET, EFI_MAX_BIT & EFI_MAX_ADDRESS
+	
+Possible impacts:
+	All EDKII native source code needs to update to use the equivelent macros (without "EFI_" prefix except for
+	EFI_FIELD_OFFSET) defined in MdePkg\Include\Base.h and MdePkg\Include\$(ARCH)\ProcessorBinding.h:
+	EFI_SIGNATURE_16 -> SIGNATURE_16
+	EFI_SIGNATURE_32 -> SIGNATURE_32
+	EFI_SIGNATURE_64 -> SIGNATURE_64
+	EFI_FIELD_OFFSET -> OFFSET_OF
+	EFI_MAX_BIT      -> MAX_BIT
+	EFI_MAX_ADDRESS  -> MAX_ADDRESS

+EDK_7467:  Non-Compatible: qhuang8
+	Remove the macro value TIME_OUT defined in MdePkg/Include/Uefi/UefiUsbLib.h and replace it with a new PCD entry:
+	gEfiMdePkgTokenSpaceGuid.PcdUsbTransferTimeoutValue  
+	
+Possible impacts:
+	All modules depending on macro TIME_OUT in MdePkg/Include/Uefi/UefiUsbLib.h should use PcdGet32 (PcdUsbTransferTimeoutValue)
+	for the USB transaction, include "PcdLib" in INF [LibraryClasses] section and add "#include <Library/PcdLib.h>" in module
+	source.

+
+	2 default values of status code PCDs updated in MdePkg.dec.
+
+	1) PcdStatusCodeValueBootServiceExit. Its value is changed from 0x3100019 to 0x3101019, which equals EFI_SOFTWARE_EFI_BOOT_SERVICE | EFI_SW_BS_PC_EXIT_BOOT_SERVICES.
+	2) PcdStatusCodeValuePeiHandoffToDxe. Its value is changed from 0x3031001 to 0x3021001, which equals EFI_SOFTWARE_PEI_CORE | EFI_SW_PEI_CORE_PC_HANDOFF_TO_NEXT. 
+
+Possible impacts:
+	Platforms which uses the default values of PCD (not overriding in DSC) would get updated report status code values for boot service exit and PEI hand-off.
+
+EDK_9385: Non-Compatible: xli24
+
+	Default value of PcdStatusCodeValueSetVirtualAddressMap updated in MdePkg.dec.
+	The value of PcdStatusCodeValueSetVirtualAddressMap is changed from 0x03101004 to 0x03111004, which equals EFI_SOFTWARE_EFI_RUNTIME_SERVICE | EFI_SW_RS_PC_SET_VIRTUAL_ADDRESS_MAP.
+
+
+Possible impacts:
+	Platforms which uses the default value of PCD (not overriding in DSC) would get updated report status code value for setting virtual address map.

+EDK_9394: Non-Compatible: qhuang8
+
+	GUID value of EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL_GUID and gEfiFirmwareVolumeBlockProtocolGuid has been changed to 
+        that of EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL_GUID defined in PI 1.2 spec.
+        	
+
+Possible impacts:
+	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.
+
+
+EDK_9817: Non-Compatible: qhuang8
+	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.
+	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. 
+
+Possible impacts:
+	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")
+	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). 
+	(There  should not be any runtime issues if the build issues have got solved in the source correctly.)
