6.5.3 Release Notes / (in progress)
</H1>
14 Mesa
6.5.3 is a
6.5 follow-on development release with many internal changes.
18 <h2>MD5 checksums
</h2>
26 <li>OpenGL
2.0 support.
27 <li>Entirely new Shading Language code generator.
28 <li>Much faster software execution of vertex, fragment shaders.
29 <li>New vertex buffer object infrastructure (replaces old array_cache code).
30 <li>Updated glext.h file (version
39)
31 <li>Updated glxext.h file (version
18)
32 <li>GL_MAX_DRAWBUFFERS is now
4 (software rendering) so
33 "multiple render targets" are really supported.
38 <li>Fog was errantly applied when a fragment shader was enabled (bug
9346)
39 <li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug
9445)
40 <li>With
32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
41 <li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
42 <li>1D convolution state could effect
2D image transfers
43 <li>Overlapping glCopyPixels with negative Y zoom didn't work (bug
10521)
44 <li>Fixed a number of framebuffer/renderbuffer reference counting bugs
45 <li>Fixed a few bugs in software-emulated alpha planes
49 <h2>Internal code changes
</h2>
52 <li>Massive changes to the Shading Language compiler.
53 <li>The _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and
54 _TnlProgram fields have been moved.
55 <li>The ctx-
>Vertex/FragmentProgram._Current fields point to the program
56 in effect, whether it comes from a shader, user-program or generated
57 fixed-function program.
61 <h2>To Do (someday) items
</h2>
63 <li>Switch to freeglut
64 <li>Fix linux-glide target/driver.
65 <li>Improved lambda and derivative calculation for frag progs.
