-The AMD GPU Services (AGS) library provides software developers with the ability to query AMD GPU software and hardware state information that is not normally available through standard operating systems or graphic APIs. Version 4.0 of the library includes support for querying graphics driver version info, GPU performance, Crossfire™ (AMD's multi-GPU rendering technology) configuration info, and Eyefinity (AMD's multi-display rendering technology) configuration info. AGS also exposes the explicit Crossfire API extension and additional extensions supported in the AMD drivers for DirectX 11.

 In addition to the library itself, the AGS SDK includes several samples to demonstrate use of the library.
 
-**Note:** Shader extension support has been temporarily removed while we wait for an updated driver that fixes certain issues.

 ### Premake
 The Visual Studio projects in each sample's `build` directory were generated with Premake. To generate the project files yourself (for another version of Visual Studio, for example), open a command prompt in the sample's `premake` directory (where the premake5.lua script for that sample is located, not the top-level directory where the premake5 executable is located) and execute the following command:
