| 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: |
| |
| |
