26<ul>
Briane3caa5f2007-04-18 09:07:56 -0600[diff] [blame^]27<li>OpenGL 2.0 and 2.1 API support.
Brianfdf513e2007-03-13 16:12:23 -0600[diff] [blame]28<li>Entirely new Shading Language code generator.
29<li>Much faster software execution of vertex, fragment shaders.
Briane3caa5f2007-04-18 09:07:56 -0600[diff] [blame^]30<li>New vertex buffer object (vbo) infrastructure
Briand2ffe4c2007-02-20 08:38:46 -0700[diff] [blame]31<li>Updated glext.h file (version 39)
Brian906fd232007-02-20 08:41:15 -0700[diff] [blame]32<li>Updated glxext.h file (version 18)
Brian23d31ef2007-03-21 11:57:30 -0600[diff] [blame]33<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
34 "multiple render targets" are really supported.
Brian6ec4a032006-12-16 11:09:14 -0700[diff] [blame]35</ul>

37<h2>Bug fixes</h2>
38<ul>
39<li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
Brian24cf67f2007-01-05 08:41:16 -0700[diff] [blame]40<li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
Brianade39f52007-01-06 12:58:28 -0700[diff] [blame]41<li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
Brianfdf513e2007-03-13 16:12:23 -0600[diff] [blame]42<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
Brian88db19a2007-03-21 09:45:58 -0600[diff] [blame]43<li>1D convolution state could effect 2D image transfers
Brian4d864b02007-04-04 09:33:12 -0600[diff] [blame]44<li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
45<li>Fixed a number of framebuffer/renderbuffer reference counting bugs
46<li>Fixed a few bugs in software-emulated alpha planes
Briane3caa5f2007-04-18 09:07:56 -0600[diff] [blame^]47<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
48<li>Assorted DRI driver bug fixes.

52<h2>Internal code changes</h2>
Brian6ec4a032006-12-16 11:09:14 -0700[diff] [blame]53<ul>
Briane3caa5f2007-04-18 09:07:56 -0600[diff] [blame^]54<li>Old array_cache module replaced by new vbo module. All geometry
55rendering is now cast in the form of vertex buffer objects.
56<li>Massive changes to the Shading Language compiler and related state.
57<li>Vertex/fragment shaders are compiled into GPU instructions and
58programs very similar to GL_ARB_vertex/fragment_program.
59<li>Vertex and fragment programs are executed with the same code now.
60<li>The SSE-optimized vertex program path has been removed since it didn't
61support more than 12 temp registers, didn't support branching/looping, etc.
