CHANGES

08.06.03 Added GL_EXT_depth_bounds_test

01.06.03 Added GL_EXT_texture_rectangle

13.04.03 Fixed a typo in ARBvbo

24.03.03 I'm starting version numbering and protocolling the changes here from this release on. 
This version will be 1.01. The additions in this version will be 
ARB_vertex_buffer_object and hopefully cygwin support. Fixed a typo in a license.
