R600g "Soft" FP64 Shows Signs Of Life, Enabling Older GPUs To Have OpenGL 4 In 2018
Most pre-GCN AMD graphics cards are still limited to OpenGL 3.3 support at this time due to not supporting FP64. Only the HD 5800/6900 series on R600g currently have real double-precision floating-point support working right now so at present they are on OpenGL 4.3 rather than 3.3, but those other generations may be catching up soon thanks to the "soft" FP64 code.

AMDGPU DC Gets More Raven Ridge Improvements, Audio Fixes
Harry Wentland of AMD has sent out the latest batch of patches for the AMDGPU DC display code stack. Fortunately it lightens up the DRM driver by about six thousand lines thanks to removing some unused code.
Besides gutting out a chunk of unused code, the DC code has a few audio fixes (no word yet on supporting newer audio formats with DC), fixes on driver unload, a "bunch" of continued Raven Ridge display updates, and various other code clean-ups.
