Branch Changes - release/202311
Branch Changes - release/202405
===============================

202405 is a larger deviation than previous releases. As part of upstreaming changes to EDK2, the commits were reviewed, squashed, and some were dropped.
Due to these changes, there may be more work required to bring an existing platform up to 202405 compatibility.

Breaking Changes-dev
--------------------

- Incomplete
- SourceLevelDebugPkg has been dropped. Please reevaluate usage of this Package.
- MemoryBinOverrideLib and associated changes have been deprecated and dropped. Platforms should remove this library instance.
- MdeModulePkg/Application/MpServicesTest/MpServicesTest.inf has been dropped. Any reliance on this should move to using mu_plus's UefiTestingPkg/FunctionalSystemTests/MpManagement.
- NetworkPkg/SharedNetworkingPkg and NetworkPkg/SharedNetworkingPkg.fdf.inc have been dropped. Please include specific inf files in projects and directly build.
- PerformancePkg has been dropped. The functionality will be available under UefiTestingPkg in mu_plus.
- UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLibMu has been dropped. Please use UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib.
- MdeModulePkg/Library/PeiReportStatusCodeOnlyLib/PeiReportStatusCodeLib.inf has been dropped. Please use standard PeiReportStatusCodeLib.
- MuPreExitBootServices has been removed in favor of gEfiEventBeforeExitBootServicesGuid. gEfiEventBeforeExitBootServicesGuid can be signaled multiple times, so be sure to close the events that are being signaled when this is changed.
- AmdSvsmLib is now a required library for IA32/X64 platforms using UefiCpuPkg/Library/MpInitLib/DxeMpInitLib,UefiCpuPkg/Library/MpInitLib/PeiMpInitLib.
- MdePkg/Library/CompilerIntrinsics no longer contains strcmp functionality.

- The strcmp functionality moved to CryptoPkg/Library/BaseCryptLib/SysCall/CrtWrapper.c where it is available to the third-party crypto code that previously used the code from the library.
- NetworkPkg requires EFI_RNG_PROTOCOL and EFI_HASH2_PROTOCOL to be available. This is part of CVE-2023-45237.
- CryptoBinPkg requires the platform to supply EFI_RNG_PPI in the Pei phase, and EFI_RNG_PROTOCOL in the Dxe phase.
apop5 marked this conversation as resolved.
Show resolved Hide resolved
- RngPei can be used to produce the RNG PPI. See [SecurityPkg/RandomNumberGenerator/RngPei](https://github.com/microsoft/mu_tiano_plus/tree/release/202405/SecurityPkg/RandomNumberGenerator/RngPei) in Mu Tiano Plus.
- TOOL_CHAIN_TAG=GCC and TOOL_CHAIN_TAG=GCC5 are both supported. GCC will become the normal in a future release.
- ImageValidation will now run on all systems with a default configuration. This will verify generated images are ready for memory protections. Details available [Here](.pytool\Plugin\ImageValidation\ReadMe.md).
