+ Mesa 6.4 Release Notes
+
+ October 24, 2005
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.3) designate new developmental releases.
+Even numbered versions (such as 6.4) designate stable releases.
+
+
+6.4 is a bug-fix release. See the VERSIONS file for details.
+
+
+
+GLUT tarball
+------------
+
+Starting with 6.4, the GLUT library sources are distributed in a separate
+tarball. This was done at the request of Linux distro vendors who prefer
+to use freeglut.
+
+
+
+
+Driver Status
+---------------------- ----------------------
+DRI drivers varies with the driver
+XMesa (Xlib) implements OpenGL 1.5
+OSMesa (off-screen) implements OpenGL 1.5
+Windows/Win32 implements OpenGL 1.5
+Glide (3dfx Voodoo1/2) requires updates
+SVGA requires updates
+DJGPP requires updates
+GGI requires updates
+BeOS requires updates
+Allegro requires updates
+D3D requires updates
+
+The drivers which require updates mostly need to be updated to work
+with the new gl_renderbuffer / gl_framebuffer infrastructure introduced
+in Mesa 6.3.

- assorted DRI driver fixes
+6.4 October 24, 2005
+ New:
+ - Added a fast XOR line drawing function in Xlib driver
+ - Added support for GL_ARB_texture_mirrored_repeat to savage
+ driver (supported only on Savage4 hardware).
+ Changes:
+ - Mesa now packaged in three parts: Library, Demos and GLUT
+ Bug fixes:
+ - GLX_X_RENDERABLE token wasn't accepted by glXChooseFBConfig
+ - Some files were present multiple times in the 6.3.2 tarballs
+ - r200_vtxtmp_x86.S file was missing from 6.3.2 tarball (bug 4207)
+ - glxgears_fbconfig demo didn't work (bug 4237)
+ - fixed bug when bilinear sampling 2d textures with borders
+ - glXCreatePbuffer() could segfault instead of returning 0 (bug 4235)
+ - fixed undefined frexp and rand in X.org libGLcore.a (bug 4242)
+ - fixed a few problems with proxy color tables (bug 4270)
+ - fixed precision problem in Z clearing (bug 4395)
+ - glBitmap, glDraw/CopyPixels mistakenly generated selection hits
+ - fixed potential segfault caused by reading pixels outside
+ of renderbuffer bounds
+ - glGetTexLevelParameter didn't accept GL_TEXTURE_DEPTH_SIZE_ARB
+ - fixed memory corruption bug involving software alpha buffers
+ - glReadPixels clipped by window bounds was sometimes broken
+ - glDraw/CopyPixels of stencil data ignored the stencil write mask
+ - glReadPixels from a texture bound to a framebuffer object didn't work
+ - glIsRender/FramebufferEXT weren't totally correct
+ - fixed a number of point size attenuation/fade bugs
+ - fixed glFogCoord bug 4729
+ - GLX encoding for transpose matrix functions was broken
+ - fixed broken fragment program KIL and SWZ instructions
+ - fragment programs that wrote result.depth.z didn't work
+
+
6.5 month, day, 2005
New:
+ - GL_EXT_packed_depth_stencil extension
+ - GL_EXT_timer_query extension
- reflect demo improved to support multiple windows
- singlebuffer demo (shows no/little-flicker single-buffered rendering)
- r200: enable GL_ARB_texture_env_crossbar, separate the texture
sampling unit bits from the texture env combine enable bits
- - GL_EXT_timer_query extension
- r200: add support for GL_ATI_fragment_shader
- added fast XOR-mode line drawing optimization
- radeon: add support for all 3 tmus, GL_ARB_texture_cube_map

information.

<p>
-Mesa 5.x supports the OpenGL 1.4 specification.
+Mesa 6.x supports the OpenGL 1.5 specification.
</p>
<h2>1.2 Does Mesa support/use graphics hardware?</h2>
<p>
-Yes. Specifically, Mesa serves as the OpenGL core for the open-source
-
XFree86/DRI OpenGL drivers. See the <a href="http://dri.sf.net/">DRI
+Yes. Specifically, Mesa serves as the OpenGL core for the open-source DRI
+
drivers for XFree86/X.org. See the <a href="http://dri.sf.net/">DRI
website</a> for more information.

Still, Mesa serves at least these purposes:

<ul>
-<li>Mesa is used as the core of the open-source XFree86/DRI hardware drivers.
+<li>Mesa is used as the core of the open-source XFree86/X.org DRI

</li>
<li>Mesa is quite portable and allows OpenGL to be used on systems
that have no other OpenGL solution.
<h2>1.4 What's the difference between"Stand-Alone" Mesa and the DRI drivers?</h2>
<p>
<em>Stand-alone Mesa</em> is the original incarnation of Mesa.
-On systems running the X Window System, it does all its rendering through
-the Xlib API.
+On systems running the X Window System it does all its rendering through

<ul>
<li>The GLX API is supported, but it's really just an emulation of the
real thing.
<h2>1.5 How do I upgrade my DRI installation to use a new Mesa release?</h2>
<p>
-You don't! A copy of the Mesa source code lives inside the XFree86/DRI source
-tree and gets compiled into the individual DRI driver modules.
-If you try to install Mesa over an XFree86/DRI installation, you'll lose
-hardware rendering (because stand-alone Mesa's libGL.so is different than
-the XFree86 libGL.so).
-</p>
-<p>
-The DRI developers will incorporate the latest release of Mesa into the
-DRI drivers when the time is right.
-</p>
-<p>
-To upgrade, either look for a new release of <a href="http://www.xfree86.org"
-target="_parent">XFree86</a> or visit the
-<a href="http://dri.sf.net" target="_parent">DRI website</a> to see
-if there's newer drivers.
+This wasn't easy in the past.
+Now, the DRI drivers are included in the Mesa tree and can be compiled
+separately from the X server.
+Just follow the Mesa <a href="install.html">compilation instructions</a>.
</p>
</ul>
<p>
-Now, Mesa again uses a conventional Makefile system (as it did originally).
+Now Mesa again uses a conventional Makefile system (as it did originally).
Basically, each Makefile in the tree includes one of the configuration

The config files specify all the variables for a variety of popular systems.
