+\r
+ Possible Impacts:\r
+\r
+ 1) Platform modules that reference PeiPiLibBuildPiFvInfoPpi and GetSectionFrom*Fv should reference the new\r
+ names defined.\r
+ 2) Platform DSC file that specifying library instance for PiLib should be updated to add one line (a example \r
+ is given below):\r
+ [LibraryClasses.common.DXE_DRIVER]\r
+ ...\r
+ DxePiLib|MdePkg/Library/DxePiLib/DxePiLib.inf\r
+ ...\r
+ 3) Platform DSC file including modules that make use of API from PeiPiLib.h should add the following line (a example \r

+ Class General Definitions: NULL_HANDLE definition is removed from UefiBaseType.h. If any modules referencs NULL_HANDLE, they should be updated to use NULL. \r
+ \r
+EDK_5869: Non-Compatible: qhuang8\r
+ Class General Definitions: Update the macro ALIGN_VARIALBE to drop the second parameter.\r
+ \r

+ Library API moved from HiiLib to UefiLib.\r
+ \r
+ Code Change:\r
+ Change HiiLibGetCurrentLanguage to GetCurrentLanguage and moved it from HiiLib to UefiLib.\r
+\r
+ Possible Impacts:\r
+ All module that reference HiiLibGetCurrentLanguage should be updated in the following step:\r
+ 0) Change HiiLibGetCurrentLanguage to GetCurrentLanguage.\r
+ 1) Add UefiLib to [LibraryClass] in INF if it is not included before.\r
+ 2) Remove HiiLib from [LibraryClass] if HiiLibGetCurrentLanguage is the only API from original HiiLib referenced by this module.\r
+ 3) Add UefiLib to [LibraryClasses.common.Module Type] for the affected module if UefiLib is not in the list.\r
+ \r
+EDK_5989: Non-Compatible: qwang12\r
+ Library API name changed:\r
+ In IfrSupportLib,\r
+ Rename BufToHexString to BufInReverseOrderToHexString \r

+\r
+Possible Impacts:\r
+ All module that reference BufToHexString or HexStringToBuf should be updated in the following step:\r

+ 2) Change HexStringToBuf to HexStringToBufInReverseOrder\r

+ Module type Include file is not included on default.\r
+ In Protocol/PPI/GUID/Libary header file, the "#include" of the module type header file such as <Base.h>, <PiPei.h>, <PiDxe.h> and \r
+ <Uefi.h> are removed. The module (DXE driver, UEFI Driver, PEIM) should include these files if required.\r
+\r
+Possible Impacts:\r
+ Customer's module (DXE driver, UEFI Driver, PEIM) may failed to build as module type header file such as <Base.h>, <PiPei.h>, <PiDxe.h>\r
+ <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\r
+ because of some undefined basic data type such as "EFI_GUID", module developer should include the module type header file accordingly.\r

+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.\r

+ a build break (mismatch of data type) may occur.\r
+ \r

+\r
+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
+\r
+Possible Impacts:\r
+ Customer's module that reference SafeFreePool need to updated. Otherwise\r
+ a build break may occur.\r

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

+ A bundle of library class/instance renames, moves and merges:\r
+ 1. Rename library class UsbLib to UefiUsbLib\r
+ 2. Rename library class ScsiLib to UefiScsiLib\r
+ 3. Rename library class PalCallLib to PalLib\r
+ 4. Rename library class DxePiLib to DxeSerivcesLib and drop the prefix "PiLib" to all its APIs.\r
+ 5. Merge library class PiPeiLib to PeiServicesLib and rename the PiLibInstallFvInfoPpi() to PeiServicesInstallFvInfoPpi()\r
+ 6. Move library class HiiLib to MdeModulePkg\r
+ 7. Move library class IfrSupportLib to MdeModulePkg\r
+ 8. Move library class FvbServiceLib to MdeModulePkg\r

+ 10. Move library instance UefiHiiLib to MdeModulePkg\r
+ 11. Move library instance UefiIfrSupportLib to MdeModulePkg\r
+\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

+ \r
+Possible Impacts:\r
+ Modules depending on UefiScsiLib for these macros should update the source to use new UefiLib macros\r
+ EFI_TIMER_PERIOD_MICROSECONDS(X), EFI_TIMER_PERIOD_MILLISECONDS(X) and EFI_TIMER_PERIOD_SECONDS(X) for managing Timer Events.\r
