| Mesa Versions |
| ============= |
| |
| Major Versions |
| -------------- |
| |
| This is a summary of the major versions of Mesa. Mesa's major version |
| number has been incremented whenever a new version of the OpenGL |
| specification is implemented. |
| |
| Version 12.x features |
| ^^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 12.x of Mesa implements the OpenGL 4.3 API, but not all drivers |
| support OpenGL 4.3. |
| |
| Initial support for Vulkan is also included. |
| |
| Version 11.x features |
| ^^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 11.x of Mesa implements the OpenGL 4.1 API, but not all drivers |
| support OpenGL 4.1. |
| |
| Version 10.x features |
| ^^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 10.x of Mesa implements the OpenGL 3.3 API, but not all drivers |
| support OpenGL 3.3. |
| |
| Version 9.x features |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 9.x of Mesa implements the OpenGL 3.1 API. While the driver for |
| Intel Sandy Bridge and Ivy Bridge is the only driver to support OpenGL |
| 3.1, many developers across the open-source community contributed |
| features required for OpenGL 3.1. The primary features added since the |
| Mesa 8.0 release are GL_ARB_texture_buffer_object and |
| GL_ARB_uniform_buffer_object. |
| |
| Version 9.0 of Mesa also included the first release of the Clover state |
| tracker for OpenCL. |
| |
| Version 8.x features |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 8.x of Mesa implements the OpenGL 3.0 API. The developers at |
| Intel deserve a lot of credit for implementing most of the OpenGL 3.0 |
| features in core Mesa, the GLSL compiler as well as the i965 driver. |
| |
| Version 7.x features |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 7.x of Mesa implements the OpenGL 2.1 API. The main feature of |
| OpenGL 2.x is the OpenGL Shading Language. |
| |
| Version 6.x features |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| Version 6.x of Mesa implements the OpenGL 1.5 API with the following |
| extensions incorporated as standard features: |
| |
| - GL_ARB_occlusion_query |
| - GL_ARB_vertex_buffer_object |
| - GL_EXT_shadow_funcs |
| |
| Also note that several OpenGL tokens were renamed in OpenGL 1.5 for the |
| sake of consistency. The old tokens are still available. |
