Mesa 3.3 release notes
+ July 21, 2000
+
PLEASE READ!!!!
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.2.1) designate stable releases.
+
+Mesa 3.3 has a undergone many internal changes since version 3.2
+and features a lot of new extensions. 3.3 is expected to be pretty
+stable, but perhaps not as stable as 3.2 which has been used by
+thousands of users over the past months.
+
+Everyone is encouraged to try Mesa 3.3. Bugs should be reported to
+the Mesa bug database on www.sourceforge.net.
+
+
Header file / GLenum changes
----------------------------
The glapitemp.h template should be reusable for all sorts of OpenGL
projects.
+The new dispatch code has also optimized with x86 assembly code.
+This optimization eliminates copying the function arguments during
+dispatch.
+
+
New thread support
------------------
penalty for typical single-thread applications. See the glapi.c
file for details.
+The Xlib driver (XMesa) is now thread-safe as well. Be sure to
+call XInitThreads() in your app first. See the xdemos/glthreads.c
+demo for an example.

Make configuration changes
New extensions
--------------
-GL_EXT_transpose_matrix
- Adds glLoadTransposeMatrix() and glMultTransposeMatrix() functions.
- See http://reality.sgi.com/opengl/arb/extensions/ext_text/GL_EXT_transpose_matrix.txt
+GL_ARB_transpose_matrix
+ Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
+ functions.
+
+GL_ARB_texture_cube_map
+ For cube-based reflection mapping.
GL_EXT_texture_add_env
Adds GL_ADD texture environment mode.
GL_EXT_histogram
Compute histograms for glDraw/Read/CopyPixels.
+GL_EXT_blend_func_separate
+ This is the same as GL_INGR_blend_func_separate.
+
+GL_ARB_texture_cube_mapping
+ 6-face cube mapping, nicer than sphere mapping
+
+GL_EXT_texture_env_combine
+ For advanced texture environment effects.
+
+
+Documentation for all these functions can be found at
+http://oss.sgi.com/projects/ogl-sample/registry/
+
GLX_SGI_make_current_read functionality
+OpenGL Conformance
+------------------
+
+Mesa now passes all the OpenGL 1.1 conformance tests, except for
+antialiased lines. AA lines fail on some, but not all, the tests.
+In order to fix the remaining failures, a new AA line algorithm will
+be needed (which computes coverage values for end-point fragments).
+This will be done for Mesa 3.5/3.6.
+
+
+
+OpenGL 1.2 GL_ARB_imaging subset
+--------------------------------
+
+Mesa 3.3 implements all the features of GL_ARB_imaging except for
+image convolution. This will (hopefully) be done for Mesa 3.5/3.6.
