+<H1>Mesa 7.2 Release Notes / 20 September 2008</H1>
+
+<p>
+Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a
+new development release.
+</p>
+<p>
+Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by
+glGetString(GL_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 2.1.
+</p>
+<p>
+Note that this version of Mesa does not use the GEM memory manager.
+The master branch of git uses GEM.
+The prototype DRI2 code that was in 7.1 has also been removed.
+</p>
+<p>
+DRM version 2.3.1 should be used with Mesa 7.2
+</p>

+<li>i965 driver: added support for G41 chipset (Intel)

+
+<h2>Bug fixes</h2>
+<ul>
+<li>Fixed display list bug involving primitives split across lists (bug 17564)
+<li>Fixed some issues with glBindAttribLocation()
+<li>Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834)
+<li>Assorted bug fixes for Ming build
+<li>Fixed some vertex/pixel buffer object reference counting bugs
+<li>Fixed depth/stencil bug in i915/945 driver
+<li>Fixed some shader flow control bugs in i965 driver
+<li>Fixed a few tdfx driver bugs which prevented driver from working
+<li>Fixed multisample enable/disable bug
+</ul>
+
+<h2>Changes</h2>
+<ul>
+<li>Updated SGI header files with new license terms.
+</ul>
+
+
+
+<h2>To Do (someday) items</h2>
+<ul>
+<li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy().
+Probably do the same for malloc, calloc, etc.
+The wrappers were useful in the past for memory debugging but now we
+have valgrind.  Not worried about SunOS 4 support anymore either...
+<li>Switch to freeglut
+<li>Fix linux-glide target/driver.
+<li>Improved lambda and derivative calculation for frag progs.
