13 Mesa uses an even/odd version number scheme like the Linux kernel.
14 Odd numbered versions (such as 6.3) designate new developmental releases.
15 Even numbered versions (such as 6.2) designate stable releases.
22 GL_ARB_draw_buffers - allows a fragment program to write to a number of
23 separate color buffers, instead of just one.
25 GL_OES_read_format - allows one to query the fastest glReadPixels format
28 GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
30 GL_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.
34 DirectFB driver, contributed by Claudio Ciccani. See docs/README.directfb
39 Vertex/Fragment Program PRINT Instruction
40 -----------------------------------------
42 The GL_NV_vertex_program and GL_NV_fragment_program languages have been
43 extended with a PRINT instruction.
47 glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
48 --------------------------------------------------------------------
50 To match the behaviour of other OpenGL implementations, glDeleteTextures,
51 glDeletePrograms and glDeleteBuffers have been modified so that:
53 * The named texture/program/buffer ID is immediately freed for re-use.
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
59 Previously, the texture/program/buffer ID wasn't freed until the object
62 Note that textures, programs and buffers can be shared by several rendering
63 contexts so they can't be deleted until they're unbound in _all_ contexts.
67 GL_EXT_framebuffer_object changes
68 ---------------------------------
70 Implementing this extension involved changing a lot of code (for the better).
72 The gl_framebuffer object now a collection of gl_renderbuffer objects.
73 Renderbuffers may store colors, stencil indices, or depth values. The
74 gl_framebuffer and gl_renderbuffer types are object-oriented in design.
76 All the old RGB, color index, stencil and depth-related span functions for
77 reading/writing pixels from/to buffers has changed. Now, all pixels are
78 read/written through a set of common renderbuffer functions (methods).
80 Most device drivers have been updated for these changes, but some haven't.
87 Increase MAX_DRAWBUFFERS
88 driver hooks for BeginQuery/EndQuery
95 The main/get.c file is now generated with a Python script (get_gen.py).
