Which version of spec/doc are you reading?

Hi, all, I’m new here.

There are many versions of OpenGL out there, which version is most widely used by real programmers? I heard Windows are still at 1.2 (or maybe 1.1), I’m wondering which version of the documentation and specification are people here reading?


Well, my WindowsME/Geforce2 MX400 machine, is using version 1.3.1 as lesson 24 of Nehe’s tutorials grab from the graphics information. But I use whatever information I can get my hands on but really concentrate on 1.2 based documentation.
