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