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

@@ -32,26 +64,33 @@ TBD

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 driver bug fixes. +

Fixed a number of bugs that prevented "depth-peeling" rendering from working.

Internal code changes

The _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and -_TnlProgram fields have been moved. -
The ctx->FragmentProgram._Active field has been removed. -
The ctx->Vertex/FragmentProgram._Current fields point to the program -in effect, whether it comes from a shader, user-program or generated -fixed-function program. -
The _UseTexEnvProgram field has been removed. +
Old array_cache module replaced by new vbo module. All geometry +rendering is now cast in the form of vertex buffer objects. +
Massive changes to the Shading Language compiler and related state. +
Vertex/fragment shaders are compiled into GPU instructions and +programs very similar to GL_ARB_vertex/fragment_program. +
Vertex and fragment programs are executed with the same code now. +
The SSE-optimized vertex program path has been removed since it didn't +support more than 12 temp registers, didn't support branching/looping, etc.

To Do (someday) items

Switch to freeglut -
Increase MAX_DRAWBUFFERS
Fix linux-glide target/driver.
Improved lambda and derivative calculation for frag progs.
