 ## Release Notes
 
+* As of the March 2022 release, legacy Xbox One XDK support requires the XDK April 2018 release or later. Upgrading to the Microsoft GDKX is strongly recommended.

 * In the June 2021 release or later, the VS 2019 projects of this library build the HLSL shaders with Shader Model 6 via DXC. Since the NuGet still builds using VS 2017, the build-in shaders in that version are currently Shader Model 5.1. See [this wiki page](https://github.com/microsoft/DirectXTK12/wiki/Shader-Model-6) for more information. The Microsoft GDK projects always use Shader Model 6.
 
 * Starting with the June 2020 release, this library makes use of [typed enum bitmask flags](https://walbourn.github.io/modern-c++-bitmask-types/) per the recommendation of the _C++ Standard_ section *17.5.2.1.3 Bitmask types*. This may have *breaking change* impacts to client code:
