"This is also the first RadeonHD release that has DRI (Direct Rendering Infrastructure) support for the ATI R500 and RS600 series. Furthermore, there is the X-Video / TexturedVideo support, CP-based (Command Processor) 2D acceleration, EXA Render acceleration, support for scaled modes, RandR support for backlight controls, and various other fixes. This driver is a big step forward from the previous 1.2.1 release."
