14Mesa 6.5.2 is a 6.5 follow-on development release mostly consisting of
15<a href="versions.html#6.5.1">bug fixes</a>.

25<h2>New features</h2>
26<ul>
27<li>New DRI memory manager system.  Currently used by the i915tex driver.
28Other DRI drivers will be updated to use the new memory manager in coming
29months.
30<br>
31To use the new driver you'll need the most recent DRM library and drivers
32(version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
33<br>
34New features resulting from this work include:
35<ul>
36<li>EXT_framebuffer_objects, render to texture
37<li>ARB_pixel_buffer_objects
38<li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
39<li>Accelerated texture uploads from pixel buffer objects
40<li>Potentially texturing directly from the pixel buffer object (zero 
41copy texturing).
42</ul>
43<li>New Intel i965 DRI driver
44<li>New <code>minstall</code> script to replace normal install program
45<li>Faster fragment program execution in software
46<li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
47    GLX_SGI_make_current_read</a> to the following drivers:</li>
48    <ul>
49    <li>radeon</li>
50    <li>savage</li>
51    <li>mga</li>

55<h2>Bug fixes</h2>
56<ul>
57<li>fixed invalid memory read while rendering textured points (bug 8320)
58<li>fixed problems with freebsd-dri configuration (bug 8344)
59<li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
60<li>OPTION NV_position_invariant didn't work in NV vertex programs
61<li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
62<li>Line clipping was broken in some circumstances
63<li>fragment.fogcoord register didn't always contain the correct value
64<li>RGBA logicops didn't work reliably in some DRI drivers
65<li>Fixed broken RGBA LogicOps in Intel DRI drivers
66<li>Fixed some fragment program bugs in Intel i915 DRI driver
67<li>Fixed glGetVertexAttribfvARB bug 8883
68<li>Implemented glGetUniform[fi]vARB() functions
69<li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
70<li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
71<li>Fixed broken "mgl" name mangling
72</ul>

75<h2>Internal code changes</h2>
76
77<ul>
78<li>The device driver functions ResizeBuffers and GetBufferSize have been
79decprecated.
80<li>OpenGL 2.0 and 2.1 support is nearly done.  We need to do quite a bit
81more testing of the shading language functions.
82</ul>
83
84
85<h2>To Do (someday) items</h2>
86<ul>
87<li>Switch to freeglut
88<li>Increase MAX_DRAWBUFFERS
89<li>Fix linux-glide target/driver.
90<li>Improved lambda and derivative calculation for frag progs.
91</ul>
