  10 Introduction
  11 ------------
  12
  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.

  19 New Features
  20 ------------
  21
  22 GL_ARB_draw_buffers - allows a fragment program to write to a number of
  23   separate color buffers, instead of just one.
  24
  25 GL_OES_read_format - allows one to query the fastest glReadPixels format
  26   and datatype.
  27
  28 GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
  29
  30 DirectFB driver, contributed by Claudio Ciccani.  See docs/README.directfb
  31 for details.

  35 Vertex/Fragment Program PRINT Instruction
  36 -----------------------------------------
  37
  38 The GL_NV_vertex_program and GL_NV_fragment_program languages have been
  39 extended with a PRINT instruction.

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

  74 Miscellaneous
  75 -------------
  76
  77 The main/get.c file is now generated with a Python script.
