+ Mesa 6.0 release notes
+
+ January 16, 2004
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 5.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+Mesa version 6.0 signifies two things:
+
+ 1. A stabilization of the 5.1 development release
+ 2. Implementation of the OpenGL 1.5 specification. When you query
+ glGetString(GL_VERSION) "1.5" will be returned (as long as the
+ driver supports all the required features).
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+ Mesa 1.x == OpenGL 1.0
+ Mesa 2.x == OpenGL 1.1
+ Mesa 3.x == OpenGL 1.2
+ Mesa 4.x == OpenGL 1.3
+ Mesa 5.x == OpenGL 1.4
+ Mesa 6.x == OpenGL 1.5
+
+
+
+New Features
+------------
+
+Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
+extensions. These extensions were simply promoted to standard features:
+
+ GL_ARB_occlusion_query extension
+ GL_ARB_texture_non_power_of_two extension
+ GL_ARB_vertex_buffer_object extension
+ GL_EXT_shadow_funcs
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on
+the device driver. For example, if the driver enables all the ARB
+extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION)
+will return "1.3". Otherwise, it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time. We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:
+
+
+Driver Status
+---------------------- ---------------------
+XMesa (Xlib) implements OpenGL 1.5
+OSMesa (off-screen) implements OpenGL 1.5
+FX (3dfx Voodoo1/2) implements OpenGL 1.3

+Wind River UGL implements OpenGL 1.3
+Windows/Win32 implements OpenGL 1.5
+DJGPP implements OpenGL 1.5
+GGI implements OpenGL 1.3
+BeOS implements OpenGL 1.5
+Allegro needs updating
+D3D needs updating
