| 11 | <H1>Mesa 7.5 Release Notes / date TBD</H1> |
| 12 | |
| 13 | <p> |
| 14 | Mesa 7.5 is a new development release. |
| Brian Paul | ce01de5 | 2009-04-07 18:23:21 -0600 | [diff] [blame] | 15 | People who are concerned with stability and reliability should stick |
| Brian Paul | e4e7ecc | 2009-04-30 17:17:31 -0600 | [diff] [blame] | 16 | with the 7.4.x branch or wait for Mesa 7.5.1. |

| 19 | The main new feature of Mesa 7.5 is the |
| 20 | <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D" |
| 21 | target="_parent">Gallium3D</a> infrastructure. |

| 24 | Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by |
| 25 | glGetString(GL_VERSION) depends on the particular driver being used. |
| 26 | Some drivers don't support all the features required in OpenGL 2.1. |

| Brian Paul | 675b1ca | 2009-04-30 17:11:20 -0600 | [diff] [blame] | 30 | for DRI hardware acceleration. |
| 31 | </p> |
| 32 | <p> |
| 33 | Note that the Mesa project is no longer using odd/even version numbers |
| 34 | to indicate development/stable releases. |
| 35 | The so-called development releases have been fairly stable. |
| 36 | If you're especially concerned with stability you should probably look for |
| 37 | "point" releases such as 7.5.1 which will be a bug-fix release. |

| Brian Paul | ce01de5 | 2009-04-07 18:23:21 -0600 | [diff] [blame] | 49 | <li>Gallium - this is the new architecture for OS-independent and |
| 50 | API-independent 3D drivers. |
| 51 | Gallium3D is intended for GPUs that fully support vertex/fragment shaders. |
| 52 | The Gallium3D drivers currently included are: |
| 53 | <ul> |
| 54 | <li>softpipe - a software/reference driver |
| 55 | <li>i915 - Intel 915/945 driver |
| 56 | <li><a href="cell.html">Cell</a> - IBM/Sony/Toshiba Cell processor driver |
| 57 | <li>nouveau - preliminary driver for NVIDIA GPUs (still under development) |
| 58 | <li>r300 - preliminary driver for R300 (still under development) |
| 59 | </ul> |
