Mesa 6.5.1 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.

Mesa 6.5.1 is a 6.5 follow-on development release mostly consisting of bug fixes (See the versions.html file)

New Features

• Intel i965 "broadwater" DRI driver
• GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex arrays in an object.
• GL_EXT_texture_sRGB - non-linearly mapped texture formats
• GL_EXT_gpu_program_parameters - addes a few new functions for setting multiple vertex/fragment program parameters with one call.

Internal code changes

A number of Mesa program-related structs were renamed. For example struct vertex_program is now struct gl_vertex_program. All the effected drivers have been updated.

Ian Romanick updated the GL API dispatch code in a number of ways. First, many old/unused extensions were removed. Second, the static entrypoints for some extensions were removed. This means GL function pointers will have to be used more often (e.g. use glXGetProcAddressARB()).

To Do (someday) items

• Switch to freeglut
• Increase MAX_DRAWBUFFERS
• Fix linux-glide target/driver.
• Fix lambda calculation for frag progs.
