10Introduction
11------------
12
13Mesa uses an even/odd version number scheme like the Linux kernel.
14Odd numbered versions (such as 5.1) designate new developmental releases.
15Even numbered versions (such as 6.0) designate stable releases.
16
17Mesa 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
25Note that the Mesa major version number is incremented with the OpenGL
26minor 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

37New Features
38------------
39
40Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
41extensions.  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

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