1 2 Mesa 6.0 release notes 3 4 January 16, 2004 5 6 PLEASE READ!!!! 7 8 9 10 Introduction 11 ------------ 12 13 Mesa uses an even/odd version number scheme like the Linux kernel. 14 Odd numbered versions (such as 5.1) designate new developmental releases. 15 Even numbered versions (such as 6.0) designate stable releases. 16 17 Mesa version 6.0 signifies two things: 18 19 1. A stabilization of the 5.1 development release 20 2. Implementation of the OpenGL 1.5 specification. When you query 21 glGetString(GL_VERSION) "1.5" will be returned (as long as the 22 driver supports all the required features). 23 24 25 Note that the Mesa major version number is incremented with the OpenGL 26 minor version number: 27 28 Mesa 1.x == OpenGL 1.0 29 Mesa 2.x == OpenGL 1.1 30 Mesa 3.x == OpenGL 1.2 31 Mesa 4.x == OpenGL 1.3 32 Mesa 5.x == OpenGL 1.4 33 Mesa 6.x == OpenGL 1.5 34 35 36 37 New Features 38 ------------ 39 40 Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as 41 extensions. These extensions were simply promoted to standard features: 42 43 GL_ARB_occlusion_query extension 44 GL_ARB_texture_non_power_of_two extension 45 GL_ARB_vertex_buffer_object extension 46 GL_EXT_shadow_funcs 47 48 49 50 Device Drivers 51 -------------- 52 53 Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on 54 the device driver. For example, if the driver enables all the ARB 55 extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) 56 will return "1.3". Otherwise, it'll return "1.2". 57 58 A number of Mesa's software drivers haven't been actively maintained for 59 some time. We rely on volunteers to maintain many of the drivers. 60 Here's the current status of all included drivers: 61 62 63 Driver Status 64 ---------------------- --------------------- 65 XMesa (Xlib) implements OpenGL 1.5 66 OSMesa (off-screen) implements OpenGL 1.5 67 FX (3dfx Voodoo1/2) implements OpenGL 1.3 68 SVGA implements OpenGL 1.3 69 Wind River UGL implements OpenGL 1.3 70 Windows/Win32 implements OpenGL 1.5 71 DJGPP implements OpenGL 1.5 72 GGI implements OpenGL 1.3 73 BeOS implements OpenGL 1.5 74 Allegro needs updating 75 D3D needs updating 76 77 78 79 80 Other Changes 81 ------------- 82 83 See the VERSIONS file for more details about bug fixes, etc. in Mesa 6.0. 84 85 86 ---------------------------------------------------------------------- 87
