Just this morning we were talking about the lack of activity within the RadeonHD and Nouveau drivers
, but as luck would have it, this afternoon the xf86-video-radeonhd 1.3.0 driver has been released. This is the first RadeonHD driver release since April.
Among the new features in the RadeonHD 1.3.0 driver include support for HDMI audio with the RS690 and R700 ASICs, basic power management support, EXA acceleration is enabled by default, fixed back-light handling, overhauled cursor handling, many bug fixes, and the start of some developer's documentation. Newly supported in this driver update are the support for RV740, M92, M93, and M97 GPUs.
The release announcement for the xf86-video-radeonhd 1.3.0 driver with source download links and the proper change-log can be found on the X.Org mailing list
