Mesa 6.0 release notes

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:
