  10 Introduction
  11 ------------
  12
  13 Mesa uses an even/odd version number scheme like the Linux kernel.
  14 Odd numbered versions (such as 5.1) designate new developmental releases.
  15 Even numbered versions (such as 6.0) designate stable releases.
  16
  17 Mesa version 6.0 signifies two things:
  18
  19   1. A stabilization of the 5.1 development release
  20   2. Implementation of the OpenGL 1.5 specification.  When you query
  21      glGetString(GL_VERSION) "1.5" will be returned (as long as the
  22      driver supports all the required features).
  23
  24
  25 Note that the Mesa major version number is incremented with the OpenGL
  26 minor version number:
  27
  28    Mesa 1.x  ==  OpenGL 1.0
  29    Mesa 2.x  ==  OpenGL 1.1
  30    Mesa 3.x  ==  OpenGL 1.2
  31    Mesa 4.x  ==  OpenGL 1.3
  32    Mesa 5.x  ==  OpenGL 1.4
  33    Mesa 6.x  ==  OpenGL 1.5
  34

  37 New Features
  38 ------------
  39
  40 Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
  41 extensions.  These extensions were simply promoted to standard features:
  42
  43    GL_ARB_occlusion_query extension
  44    GL_ARB_texture_non_power_of_two extension
  45    GL_ARB_vertex_buffer_object extension
  46    GL_EXT_shadow_funcs

  50 Device Drivers
  51 --------------
  52
  53 Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on
  54 the device driver.  For example, if the driver enables all the ARB
  55 extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION)
  56 will return "1.3".  Otherwise, it'll return "1.2".
  57
  58 A number of Mesa's software drivers haven't been actively maintained for
  59 some time.  We rely on volunteers to maintain many of the drivers.
  60 Here's the current status of all included drivers:
