  10 Introduction
  11 ------------
  12
  13 Mesa uses an even/odd version number scheme like the Linux kernel.
  14 Odd numbered versions (such as 6.1) designate new developmental releases.
  15 Even numbered versions (such as 6.0) designate stable releases.

  25 Driver / context changes
  26 ------------------------
  27
  28 The _mesa_create_context() and _mesa_initialize_context() function
  29 parameters have changed.  They now take a pointer to a struct
  30 dd_function_table.  Drivers can initialize this table by calling
  31 _mesa_init_driver_functions().  Drivers should then plug in the special
  32 functions they implement.  In particular, the ctx->Driver.NewTextureObject
  33 pointer _must_ be set so that the default texture objects created in
  34 _mesa_create/initialize_context() are correctly built.
  35
  36 The _mesa_init_driver_functions() function allows a lot of redundant code
  37 to be removed from the device drivers (such as initializing
  38 ctx->Driver.Accum to point to _swrast_Accum).  Adding new functions to
  39 the dd_function_table can be done with less hassle since the pointer can
  40 be initialized in _mesa_init_driver_functions() rather than in _all_ the
  41 drivers.

  45 Device Drivers
  46 --------------
  47
  48 Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
  49 depending on the device driver's capabilities.  For example, if the
  50 driver enables all the ARB extensions which are part of OpenGL 1.5
  51 then glGetString(GL_VERSION) will return "1.5".  Otherwise, it'll
  52 return "1.4" or the next lower version that implements all required
  53 functionality.
  54
  55 A number of Mesa's software drivers haven't been actively maintained for
  56 some time.  We rely on volunteers to maintain many of the drivers.
  57 Here's the current status of all included drivers:
