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 driver bug fixes. +
Fixed a number of bugs that prevented "depth-peeling" rendering from working. +

+ + +

Internal code changes

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 +
Fix linux-glide target/driver. +
Improved lambda and derivative calculation for frag progs. +

+ + +
