Mesa 6.0 release notes January 16, 2004 PLEASE READ!!!! Introduction ------------ Mesa uses an even/odd version number scheme like the Linux kernel. Odd numbered versions (such as 5.1) designate new developmental releases. Even numbered versions (such as 6.0) designate stable releases. Mesa version 6.0 signifies two things: 1. A stabilization of the 5.1 development release 2. Implementation of the OpenGL 1.5 specification. When you query glGetString(GL_VERSION) "1.5" will be returned (as long as the driver supports all the required features). Note that the Mesa major version number is incremented with the OpenGL minor version number: Mesa 1.x == OpenGL 1.0 Mesa 2.x == OpenGL 1.1 Mesa 3.x == OpenGL 1.2 Mesa 4.x == OpenGL 1.3 Mesa 5.x == OpenGL 1.4 Mesa 6.x == OpenGL 1.5 New Features ------------ Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as extensions. These extensions were simply promoted to standard features: GL_ARB_occlusion_query extension GL_ARB_texture_non_power_of_two extension GL_ARB_vertex_buffer_object extension GL_EXT_shadow_funcs Device Drivers -------------- Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the device driver. For example, if the driver enables all the ARB extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise, it'll return "1.2". A number of Mesa's software drivers haven't been actively maintained for some time. We rely on volunteers to maintain many of the drivers. Here's the current status of all included drivers: Driver Status ---------------------- --------------------- XMesa (Xlib) implements OpenGL 1.5 OSMesa (off-screen) implements OpenGL 1.5 FX (3dfx Voodoo1/2) implements OpenGL 1.3 SVGA implements OpenGL 1.3 Wind River UGL implements OpenGL 1.3 Windows/Win32 implements OpenGL 1.5 DJGPP implements OpenGL 1.5 GGI implements OpenGL 1.3 BeOS implements OpenGL 1.5 Allegro needs updating D3D needs updating Other Changes ------------- See the VERSIONS file for more details about bug fixes, etc. in Mesa 6.0. ---------------------------------------------------------------------- $Id: RELNOTES-6.0,v 1.1.1.3 2004/08/12 23:43:28 anholt Exp $
