32<h2>New features</h2>
33<ul>
34<li>New DRI memory manager system.  Currently used by the i915tex driver.
35Other DRI drivers will be updated to use the new memory manager in coming
36months.
37<br>
38To use the new driver you'll need the most recent DRM library and drivers
39(version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
40<br>
41New features resulting from this work include:
42<ul>
43<li>EXT_framebuffer_objects, render to texture
44<li>ARB_pixel_buffer_objects
45<li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
46<li>Accelerated texture uploads from pixel buffer objects
47<li>Potentially texturing directly from the pixel buffer object (zero
48copy texturing).
49</ul>
50<li>New Intel i965 DRI driver
51<li>New <code>minstall</code> script to replace normal install program
52<li>Faster fragment program execution in software
53<li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
54    GLX_SGI_make_current_read</a> to the following drivers:
55    <ul>
56    <li>radeon</li>
57    <li>savage</li>
58    <li>mga</li>
59    <li>tdfx</li>
60    </ul>
61<li>Added support for ARB_occlusion_query to the tdfx driver (Ian
62Romanick).</li>
63</ul>
64
65<h2>Bug fixes</h2>
66<ul>
67<li>fixed invalid memory read while rendering textured points (bug 8320)
68<li>fixed problems with freebsd-dri configuration (bug 8344)
69<li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
70<li>OPTION NV_position_invariant didn't work in NV vertex programs
71<li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
72<li>Line clipping was broken in some circumstances
73<li>fragment.fogcoord register didn't always contain the correct value
74<li>RGBA logicops didn't work reliably in some DRI drivers
75<li>Fixed broken RGBA LogicOps in Intel DRI drivers
76<li>Fixed some fragment program bugs in Intel i915 DRI driver
77<li>Fixed glGetVertexAttribfvARB bug 8883
78<li>Implemented glGetUniform[fi]vARB() functions
79<li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
80<li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
81<li>Fixed broken "mgl" name mangling
82<li>Indirect rending was broken for glMap* functions (bug 8899)
83</ul>
84
85
86<h2>Internal code changes</h2>
87
88<ul>
89<li>The device driver functions ResizeBuffers and GetBufferSize have been
90decprecated.
91<li>OpenGL 2.0 and 2.1 support is nearly done.  We need to do quite a bit
92more testing of the shading language functions.
93</ul>
94
95
96<h2>To Do (someday) items</h2>
97<ul>
98<li>Switch to freeglut
99<li>Increase MAX_DRAWBUFFERS
100<li>Fix linux-glide target/driver.
101<li>Improved lambda and derivative calculation for frag progs.
102</ul>
