While not major updates, the xf86-video-ati 18.1.0 and xf86-video-amdgpu 18.1.0 releases bring several new features that should boost the performance of your AMD Radeon or ATI graphics cards on various GNU/Linux distributions. Both releases are compatible with X.Org Server versions 1.13 to 1.20, the latest available right now. Highlights of xf86-video-amdgpu 18.1.0 include support for advanced color management functionality and support for X11 colormaps and gamma correction when X.Org Server runs at depth 30. Both features can be used with the new AMDGPU DC (Display Code) feature implemented in Linux kernel 4.17 or later.
