Mesa 7.2 Release Notes / 20 September 2008

+ +

+Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a +new development release. +

+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. +

+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. +

+DRM version 2.3.1 should be used with Mesa 7.2 +

New features

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

+ + +

Bug fixes

Fixed display list bug involving primitives split across lists (bug 17564) +
Fixed some issues with glBindAttribLocation() +
Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834) +
Assorted bug fixes for Ming build +
Fixed some vertex/pixel buffer object reference counting bugs +
Fixed depth/stencil bug in i915/945 driver +
Fixed some shader flow control bugs in i965 driver +
Fixed a few tdfx driver bugs which prevented driver from working +
Fixed multisample enable/disable bug +

+ +

Changes

Updated SGI header files with new license terms. +

+ + + +

To Do (someday) items

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

- fragops - emit fragment ops debug messages +
