| 10 | Introduction |
| 11 | ------------ |
| 12 | |
| 13 | Mesa uses an even/odd version number scheme like the Linux kernel. |
| 14 | Odd numbered versions (such as 6.1) designate new developmental releases. |
| 15 | Even numbered versions (such as 6.0) designate stable releases. |
| 16 | |
| 17 | |
| 18 | New Features |

| 21 | TBD |

| 25 | Driver / context changes |
| 26 | ------------------------ |
| 27 | |
| 28 | The _mesa_create_context() and _mesa_initialize_context() function |
| 29 | parameters have changed. They now take a pointer to a struct |
| 30 | dd_function_table. Drivers can initialize this table by calling |
| 31 | _mesa_init_driver_functions(). Drivers should then plug in the special |
| 32 | functions they implement. In particular, the ctx->Driver.NewTextureObject |
| 33 | pointer _must_ be set so that the default texture objects created in |
| 34 | _mesa_create/initialize_context() are correctly built. |
| 35 | |
| 36 | The _mesa_init_driver_functions() function allows a lot of redundant code |
| 37 | to be removed from the device drivers (such as initializing |
| 38 | ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to |
| 39 | the dd_function_table can be done with less hassle since the pointer can |
| 40 | be initialized in _mesa_init_driver_functions() rather than in _all_ the |
| 41 | drivers. |

| 47 | Device Drivers |
| 48 | -------------- |
| 49 | |
| 50 | Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on |
| 51 | the device driver. For example, if the driver enables all the ARB |
| 52 | extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) |
| 53 | will return "1.3". Otherwise, it'll return "1.2". |
| 54 | |
| 55 | A number of Mesa's software drivers haven't been actively maintained for |
| 56 | some time. We rely on volunteers to maintain many of the drivers. |
| 57 | Here's the current status of all included drivers: |
| 58 | |
| 59 | |
| 60 | Driver Status |
| 61 | ---------------------- --------------------- |
| 62 | XMesa (Xlib) implements OpenGL 1.5 |
| 63 | OSMesa (off-screen) implements OpenGL 1.5 |
| 64 | FX (3dfx Voodoo1/2) implements OpenGL 1.3 |
| 65 | SVGA implements OpenGL 1.3 |
| 66 | Wind River UGL implements OpenGL 1.3 |
| 67 | Windows/Win32 implements OpenGL 1.5 |
| 68 | DJGPP implements OpenGL 1.5 |
| 69 | GGI implements OpenGL 1.3 |
| 70 | BeOS implements OpenGL 1.5 |
| 71 | Allegro needs updating |
| 72 | D3D needs updating |
| 73 | |
