 # AMD AGS Library Changelog
 
+### v3.2.0 - 2016-02-12
+* Add ability to disable Crossfire
+  * This is in addition to the existing ability to enable the explicit Crossfire API
+  * Desired Crossfire mode is now passed in to `agsInit`
+  * Separate `SetCrossfireMode` function has been removed from the AGS API
+  * The `agsInit` function should now be called **prior to device creation**
+* Return library version number in the optional info parameter of `agsInit`
+* Build amd_ags DLLs such that they do not depend on any Microsoft Visual C++ redistributable packages
+
 ### v3.1.1 - 2016-01-28
 * Return null for the context when initialization fails
 * Add version number defines to `amd_ags.h`

+![AMD AGS Library](http://gpuopen-librariesandsdks.github.io/media/amd_logo_black.png)
 
 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 3.1 of the library includes support for querying graphics driver version info, GPU performance, Crossfire&trade; (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, as well as additional functionality supported in the AMD driver for DirectX 11.
