- Omit GL_ARB_texture_non_power_of_two from list of OpenGL 1.5 features
- fixed a few compilation issues on IRIX
- fixed a matrix classification bug (reported by Wes Bethel)
- we weren't reseting the vertex/fragment program error state
  before parsing (Dave Reveman)
- adjust texcoords for sampling texture rectangles (Dave Reveman)
- glGet*(GL_MAX_VERTEX_ATTRIBS_ARB) wasn't implemented
- repeated calls to glDeleteTexture(t) could lead to a crash
- fixed potential ref count bugs in VBOs and vertex/fragment programs

Changes 6.1:
New:
- Revamped Makefile system
- glXUseRotatedXFont() utility (see xdemos/xuserotfont.c)
- internal driver interface changes related to texture object
  allocation, vertex/fragment programs, BlendEquationSeparate, etc.
- option to walk triangle edges with double-precision floats
  (Justin Novosad of Discreet) (see config.h file)
- support for AUX buffers in software GLX driver
- updated glext.h to version 24 and glxext.h to version 6
- new MESA_GLX_FORCE_ALPHA and MESA_GLX_DEPTH_BITS env vars

- glFogCoord didn't always work properly
- ARB_fragment_program fog options didn't work
- frag prog TEX instruction no longer incorrectly divides s,t,r by q
- ARB frag prog TEX and TEXP instructions now use LOD=0
- glTexEnviv in display lists didn't work
- glRasterPos didn't do texgen or apply texture matrix
- GL_DOUBLE-valued vertex arrays were broken in some cases
- fixed texture rectangle edge/border sampling bugs
- sampling an incomplete texture in a fragment program would segfault
- glTexImage was missing a few error checks
- fixed some minor glGetTexParameter glitches
- GL_INTENSITY was mistakenly accepted as a  to glTexImage
- fragment program writes to RC/HC register were broken
- fixed a few glitches in GL_HP_occlusion_test extension
