NVIDIA has published a new set of drivers for Linux, Solaris and FreeBSD. The main new change compared to R331.13 is the support of NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL):

Added support for NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL). This library provides a high performance, low latency interface to capture and optionally encode the composited framebuffer of an X screen. NvFBC and NvIFR are private APIs that are only available to approved partners for use in remote graphics scenarios. Please contact NVIDIA at GRIDteam@nvidia.com for more information.

R331.20 is an OpenGL 4.4 driver and exposes 292 GL extensions like R331.13.
