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

| 18 | The main new feature of Mesa 7.5 is the |

| Brian Paul | ce01de5 | 2009-04-07 18:23:21 -0600 | [diff] [blame] | 20 | target="_parent">Gallium3D</a> infrastructure. |
| Brian Paul | d2ab930 | 2009-01-22 10:29:24 -0700 | [diff] [blame] | 21 | </p> |
| 22 | <p> |
| 23 | Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by |
| 24 | glGetString(GL_VERSION) depends on the particular driver being used. |
| 25 | Some drivers don't support all the features required in OpenGL 2.1. |

| 31 | <p> |
| 32 | Note that the Mesa project is no longer using odd/even version numbers |
| 33 | to indicate development/stable releases. |
| 34 | The so-called development releases have been fairly stable. |
| 35 | If you're especially concerned with stability you should probably look for |
| 36 | "point" releases such as 7.5.1 which will be a bug-fix release. |
