AMGX current version

I am confused about current version of AMGX and download location.

If I follow https://developer.nvidia.com/amgx link, I end up on AMGX trial download page, which says
“Updated January 2015”, and has download links like https://developer.nvidia.com/rdp/assets/amgx-redhat-65-cuda-65, which downloads what seems to be 2014 version (2014.12.22_amgx_redhat-6.5_cuda-6.5.zip) with only headers and .so library.

Github https://github.com/NVIDIA/AMGX seems to have newer version. It is also available to anyone, whereas AMGX webpage allows downloads for Reg. Developers only.

Is Github the location to get the AMGX from?
