Four months after Mesa 7.2 was released, Mesa 7.3 has now officially surfaced. Mesa 7.3 has been in testing since earlier this month with it having gone through three release candidates. The new features found in this latest version of the standard Open-Source OpenGL stack is proper support for GLSL 1.20 and the Intel DRI driver now supports the Graphics Execution Manager and Direct Rendering Infrastructure 2.
This is a brilliant open source project that has not IMO received the attention that it deserves over the years. It’s hard to believe that it’s been almost 14 years since 1.0.
A timeline of the project’s history is here: http://www.mesa3d.org/intro.htm
