GLVND, of course, being the OpenGL Vendor Neutral Dispatch library. This is the NVIDIA-led effort that was also supported by upstream Mesa/X.Org developers for in effect a "new OpenGL Linux ABI" for allowing multiple Linux OpenGL drivers to happily co-exist on the same system. This makes things much easier than having different drivers overwriting the libGL files, complications with driver installation/uninstall, etc. It was long overdue but finally was seeing upstream support in 2016.
The latest Mesa supports a GLVND-based installation and the NVIDIA proprietary driver has also been supporting GLVND installation. The main driver lacking GLVND support to date is the AMDGPU-PRO driver.
Anyhow, as brought up in this Fedora devel thread, next week a Mesa update is coming to F25 that will switch it to using GLVND. It won't mean much of a difference if you just always use the out-of-the-box Mesa drivers on Fedora, but this is good news for those installing the NVIDIA Linux driver (and eventually, AMDGPU-PRO).
