Mesa 6.5 Release Notes Introduction ------------ Mesa uses an even/odd version number scheme like the Linux kernel. Odd numbered versions (such as 6.5) designate new developmental releases. Even numbered versions (such as 6.4) designate stable releases. New Features ------------ OpenGL Shading language support This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100, GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of the work was done by Michal Krol. There's probably a fair number of bugs since this is a pretty large, complicated body of code. The OpenGL 2.0 interface to these features will be implemented in a future version of Mesa, GL_EXT_timer_query Used to measure the time of OpenGL operations at high precision. Only supported in the software/Xlib driver at this time. GL_EXT_packed_depth_stencil Defines a new GL_DEPTH_STENCIL_EXT pixel format. GL_EXT_framebuffer_blit A simplified glCopyPixels-like feature for copying pixel rectangles. GL_ARB_half_float_pixel Adds a new half-precision floating point format for image transfers, such as for glDrawPixels, glReadPixels, glTexImage, etc. Removed Extensions ------------------ The following extensions have been removed: GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query. Known Issues ------------ Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL textures should work. Driver Interface Changes ------------------------ Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by the two-sided versions: Driver.Stencil*Separate(). Render-to-texture: The functions for rendering to textures have changed. To Do (someday) items --------------------- Switch to freeglut Increase MAX_DRAWBUFFERS Fix linux-glide target/driver. Fix lambda calculation for frag progs.
