10Introduction
11------------
12
13Mesa uses an even/odd version number scheme like the Linux kernel.
14Odd numbered versions (such as 6.3) designate new developmental releases.
15Even numbered versions (such as 6.2) designate stable releases.

19New Features
20------------
21
22GL_ARB_draw_buffers - allows a fragment program to write to a number of
23  separate color buffers, instead of just one.
24
25GL_OES_read_format - allows one to query the fastest glReadPixels format
26  and datatype.
27
28GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
29
30GL_EXT_framebuffer_object - allows render-to-texture and provides a
31  window-system indepedent Pbuffer facility
32  The Mesa CVS tree contains a couple tests of this extension.
33
34DirectFB driver, contributed by Claudio Ciccani.  See docs/README.directfb
35for details.

39Vertex/Fragment Program PRINT Instruction
40-----------------------------------------
41
42The GL_NV_vertex_program and GL_NV_fragment_program languages have been
43extended with a PRINT instruction.
44
45
46
47glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
48--------------------------------------------------------------------
49
50To match the behaviour of other OpenGL implementations, glDeleteTextures,
51glDeletePrograms and glDeleteBuffers have been modified so that:
52
53  * The named texture/program/buffer ID is immediately freed for re-use.
54
55  * The actual texture object, program or buffers isn't really deleted until
56    it is no longer bound in any rendering context (the reference count
57    is zero).
58
59Previously, the texture/program/buffer ID wasn't freed until the object
60was really deleted.
61
62Note that textures, programs and buffers can be shared by several rendering
63contexts so they can't be deleted until they're unbound in _all_ contexts.

82Miscellaneous
83-------------
