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: |
