OpenGL 1.5 begins the path to having shaders.
OpenGL 2.0 finishes the path.
I don't think 2.0 is out yet however.
OpenGL version 2.0, released on September 7, 2004, is the sixth revision since the original version 1.0. Despite incrementing the major version number (to indicate support for high-level programmable shaders), version 2.0 is upward compatible with earlier versions, meaning that any program that runs with a 1.5, 1.4, 1.3, 1.2, 1.1, or 1.0 GL implementation will also run unchanged with a 2.0 GL implementation.
