 			<Uefi.h> is removed from the Protocol/PPI/GUID/Libary header file. If the module can build before the update but failed after the update
 			because of some undefined basic data type such as "EFI_GUID", module developer should include the module type header file accordingly.

+Base on PI spec, GetPeiServicesTablePointer in PeiServicesTablePointer library is updated to return CONST EFI_PEI_SERVICES**. This is a incompatible changes. All file that reference this must be updated.
+
+Possible Impacts:
+			Customer's module that reference GetPeiServicesTablePointer in PeiServicesTablePointer library may need to updated. Otherwise
+			a build break (mismatch of data type) may occur.

+
+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. 
+
+It is recommended that module writer should keep track how a pointer is allocated and free it after use.
+
+Possible Impacts:
+			Customer's module that reference SafeFreePool need to updated. Otherwise
+			a build break may occur.

+	A bundle of library class/instance renames, moves and merges:
+	1.  Rename library class UsbLib to UefiUsbLib
+	2.  Rename library class ScsiLib to UefiScsiLib
+	3.  Rename library class PalCallLib to PalLib
+	4.  Rename library class DxePiLib to DxeSerivcesLib and drop the prefix "PiLib" to all its APIs.
+	5.  Merge library class PiPeiLib to PeiServicesLib and rename the PiLibInstallFvInfoPpi() to PeiServicesInstallFvInfoPpi()
+	6.  Move library class HiiLib to MdeModulePkg
+	7.  Move library class IfrSupportLib to MdeModulePkg
+	8.  Move library class FvbServiceLib to MdeModulePkg
+	9.  Rename library instance of BasePalCallLibNull to BasePalLibNull
+	10. Move library instance UefiHiiLib to MdeModulePkg
+	11. Move library instance UefiIfrSupportLib to MdeModulePkg
+
+Possible Impacts:
+	 Every change listed above is non-backward compatible for MdePkg and other packages. It is required to update module
+	 sources (*.c;*.h), module meta data files (*.inf) and update the platform DSC files to fix the build break.
+	 However, it is less likely to bring about functional issue for these updates.

+	Remove some macro in UefiScsiLib:
+	EFI_SCSI_STALL_1_MICROSECOND, EFI_SCSI_STALL_1_MILLISECOND, EFI_SCSI_STALL_1_SECOND & EFI_SCSI_STALL_SECONDS(a)  
+	
+Possible Impacts:
+	Modules depending on UefiScsiLib for these macros should update the source to use new UefiLib macros
+	EFI_TIMER_PERIOD_MICROSECONDS(X), EFI_TIMER_PERIOD_MILLISECONDS(X) and EFI_TIMER_PERIOD_SECONDS(X) for managing Timer Events.
+	Especailly, EFI_SCSI_STALL_SECONDS(a) is simply replaced by EFI_TIMER_PERIOD_SECONDS(a)
