Shared library numbering
Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix)
shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx).
Bumping the shared library version to 2.x would cause linking problems
with existing OpenGL applications. Since OpenGL 2.x is backward
compatible with OpenGL 1.x the shared library version number doesn't
have to be incremented (which would indicate an incompatible ABI).
Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
for the same reason.
New features
- OpenGL 2.0 and 2.1 API support.
- Entirely new Shading Language code generator. See the
Shading Language page for more information.
- Much faster software execution of vertex, fragment shaders.
- New vertex buffer object (vbo) infrastructure
- Updated glext.h file (version 39)
- Updated glxext.h file (version 19)
- GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
"multiple render targets" are really supported.
Bug fixes
- Fog was errantly applied when a fragment shader was enabled (bug 9346)
- glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
- With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
- GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
- 1D convolution state could effect 2D image transfers
- Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
- Fixed a number of framebuffer/renderbuffer reference counting bugs
- Fixed a few bugs in software-emulated alpha planes
- Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
- Assorted DRI dr
