OpenGL 1.5 Specification Available for Download has posted a pdf document containing OpenGL 1.5 specifications. Full details can be found here.

"OpenGL version 1.5, released on 7/29/03, is the fifth revision since the original version 1.0. In addition to enhancments to the classical fixed-function GL pipeline in OpenGL 1.5, the OpenGL ARB also approved a related set of ARB extensions including the OpenGL Shading Language specification and the ARB shader objects, ARB vertex shader, and ARB fragment shader extensions through which high-level shading language programs can be loaded and used in place of the fixed function pipeline."


Commenting will be coming soon. In the meantime, feel free to create a discussion topic on the forums.
