documentation of new functions

i would like to know how can i find the new name of the functions of new versions of opengl ?
For instance, with GL_EXT_multi_draw_arrays, what is its new name which is incorporate at opengl 1.4 ? where can i find with the others new names ?

Here’s the one-stop-shop for all your extension needs:

Usually you can just drop the EXT/ARB off the function names when extensions get added to the core.

But to be sure get this (Link from the main page):

In you case a seach for MultiDraw turned up on page 26 with the function definitions.

It also has an appendix listing all OpenGL extensions that were promoted to core with each version.
