While it's coming late, Mesa 10.0 (formerly known as Mesa 9.3) was released in the early hours of Sunday morning.

The 10.0 release was expected a few days back, but now it's finally happened via Intel's Ian Romanick with this brief announcement.

For more details on the exciting changes found in Mesa 10.0, see this feature overview. The main feature of Mesa 10.0 is the arrival of core Mesa supporting OpenGL 3.2 and 3.3, albeit only the Intel driver is fully taking advantage of the support but the Nouveau and Radeon drivers should be caught up soon.

Mesa 10.0 is certainly worth the upgrade as shown by this week's 21-way graphics card comparison, AMD APU benchmarks on Linux, etc.
