No GPU programming guide for Geforce 10 series?

I browsed the NVidia developer site(https://developer.nvidia.com) seeking for new version of GPU programming guide for Geforce 10x series such as “http://developer.download.nvidia.com/GPU_Programming_Guide/GPU_Programming_Guide_G80.pdf”.
But it doesn’t seem to be.
is the GPU programming guide for Geforce 8/9 still enough for now?
